FIELD OF THE INVENTION
The invention relates to vehicle technology and specifically to flying objects.
All the recent man-made vehicles start and accelerate, speed up or slow down, with the help of either external force, or reaction force, or jet, or their combination. The vehicles are passive in relation to those forces, because the forces are external. Using the external thrusts confines motion possibility of the vehicles, since the vehicles need complex structures and specific conditions for their motion. For example, aircraft needs large wings and expensive airports for lifting and landing; helicopter needs very large blades of its rotor in comparison with its body. Both of them cannot fly at very high altitude because of decreasing of the air density along the altitude of the atmosphere. Spaceship needs an expensive starting complex and cannot accelerate any more after running out of fuel for jet propulsion. Therefore, the maximum speed of the man-made spaceships is very small in comparison with the light speed. On the earth surface ship needs sufficiently deep water to move, submarine cannot dive down too deep because of water pressure, automobile needs motorways, train needs railways, etc. Consequently, the mankind's transport systems are very complicated, expensive, and constrained, and have low safety.
All the man-made vehicles are passive because their motion is based on Newton's laws of motion, in accordance with that the total of internal forces of each vehicle must be zero. However, the laws are stated only for solid bodies or systems of rigid particles and the total internal force may differ from zero for some bodies of other nature. For example, the sum of internal forces of a moving charged particle can differ from zero, although the sum is rather small. So far there has been virtually no exploration of any other body, which can generate a sufficiently large total internal force for practical application in vehicle technology.
Accordingly, the main objects and advantages of my invention are to provide vehicles with mechanisms which allow the vehicles to generate their own total internal force that is their self-action force for starting, accelerating, lifting, landing, and moving in any direction in the air, cosmos, and water (if it is sealed), and on any ground surface and water surface (if the lower part of its body is sealed). The vehicles will make the mankind's transport system much more flexible, simple, cheap, safe, and faster in both the earth's environment and universe.
The above and another objects, advantages and features of my invention will become apparent following examination of drawings and ensuing description herein:
In the present invention mobile objects including all types of vehicles are constructed on the base of the self-action principle of a solid-fluid body that has been discovered recently. Each of the mobile objects is presented as a solid-fluid body, which is a hermetically sealed solid chamber filled up with a fluid and containing a set of internal solid elements. The self-action principle states that a solid-fluid body except external forces is acted upon by a self-action force that equals to the sum of the time rate of change of the momentum of the whole fluid as a lump in free space and the total force due to the pressure and shear stress distributions of the fluid over the surfaces of its solid elements reduced by the force due to its body force. Therefore, in the case of absence of external forces each of the mobile objects can accelerate itself by using its self-action force. Since the self-action force is the total of internal forces of a solid-fluid body, the mobile object constructed on the base of the self-action principle can accelerate itself in any environment (in the atmosphere, water, cosmos, etc.) without the use of jets, reactive or external forces. The other advantage of the mobile object is that its self-action force can be increases as many times as desirable due to increasing the pressure of the fluid that is usually a pressurized air or gas.
In order to produce large self-action forces for the mobile objects force generators, which are aerodynamic lift devices mounted inside the hermetically sealed solid chamber of each mobile object, are invented on the base of the technique of support of the gas on its lower surfaces in relative equilibrium. Each force generator comprises a rotary shell having an open bottom, the means supporting the gas in relative equilibrium inside said rotary shell, and the stationary means closing the open bottom of said rotary shell. The rotary shell and the means supporting the gas in relative equilibrium inside the shell constitute the rotor of the force generator. The special arrangement and strict coordination of said rotor and said stationary means supports the gas on the lower surfaces of the force generator, i.e. the rotary shell together with the stationary means, in relative equilibrium, while the relative velocity of the gas on its upper surfaces is proportional to the angular velocity of the shaft of its rotor. As a result, the force generator produces the maximum difference between the pressures of the gas acting on its lower and upper surfaces, i.e. the maximum lift.
Referring now to the drawings, a mobile object constructed in accordance with one embodiment of the present invention is indicated generally at 40 in
In operation, rotor 54 and fan 58 are driven from engine 44 through gearbox 46. During rotation of rotor 54 the working gas in the space bounded by disk-stator 52 and rotor 54 rotates together with the rotor and sweeps over the upper surface of disk-stator 52 due to dividing walls 76 which skim the upper surface of disk-stator 52 to accompany the working gas. Whereby the working gas is supported in relative equilibrium inside rotor 54. Because of the centrifugal force some part of the working gas in the space bounded by disk-stator 52 and rotor 54 is exhausted through the clearance between the upper surface of disk-stator 52 and the circumference of open bottom 72 or the bottom edge of circumferential tube 68 of rotor 54. The exhausted gas is continuously compensated by the gas flows entering into the space bounded by disk-stator 52 and rotor 54 through fan duct 60 due to the operation of fan 58. The rotation of rotor 54 creates different relative gas flows over the surfaces of disk-stator 52 and rotor 54. The different relative gas flows, in turn, exert different pressures on the surfaces. As a result, the difference in pressure distribution over the lower and upper surfaces of disk-stator 52 and the difference in pressure distribution over the lower and upper surfaces of top disk 70 of rotor 54 exert forces on disk-stator 52 and rotor 54 respectively. The sum of the forces acts on mobile object 40 through the shaft, mechanical joints, fasteners, supporters, and structural frame of the mobile object in the upward direction along shaft 56 (from the lower surface to upper surface of the disk-stator or the top disk of the rotor). The sum of the forces generated by force generator 42 is the self-action force of mobile object 40, since it is the internal force of the mobile object. The detailed discovery of the self-action force of mobile object 40 generated by its force generator 42 is explained by considering the pressure distributions of the gas flows over the solid surfaces inside mobile object 40.
Those skilled in the art know that in accordance with Newton's laws of motion the total of internal forces of a solid body or a system of solid particles vanishes. In other words, the discovery of the self-action force of mobile object 40 cannot be explained in the scope of Newton's mechanics. Therefore, for the sake of the precise and well-grounded discovery of the self-action force of mobile object 40 a new mechanics must be founded. For assertion of the discovery of the self-action force of mobile object 40 the fundamentals of the mechanics of solid-fluid bodies have been established and applied to the analysis of mobile object 40. In the new mechanics mobile object 40 is considered as a whole mechanical system, which is called a solid-fluid body. The elaboration of the establishment is presented below.
Under a solid-fluid body we mean a hermetically sealed solid chamber filled up with a fluid and containing a set of internal solid elements. Suppose the solid-fluid body comprises N solid elements, among which its solid chamber is labeled as Ith solid element and its internal solid elements are labeled as 2nd to Nth solid elements. Then the momentum equation for the ith solid element can be written as
In Eq. (501) {right arrow over (F)}ij stands for the force on the ith solid element due to the jth solid element; {right arrow over (F)}i(p) and {right arrow over (F)}i(τ) are the forces on the ith solid element due to the pressure and shear stress distributions of the fluid respectively over the surface of the ith solid element; and {right arrow over (F)}i(e) is the total external force acting on the ith solid element.
Further, the momentum equation for the total fluid can be written in the integral form as follows
where ν(t) and S(t) are the volume and boundary surface of the fluid respectively. They are time functions due to motion of the internal solid elements. The first term in the left side is the time rate of change of the momentum of the fluid due to motion of the fluid with the velocity {right arrow over (ν)}0={right arrow over (ν)}+{right arrow over (V)}, in which {right arrow over (ν)} is the velocity of the whole solid-fluid body or the velocity of the solid chamber, {right arrow over (ν)}={right arrow over (ν)}1, and {right arrow over (V)} is the velocity of the fluid particles relative to the solid chamber. The second term in the left side is the flow of momentum out of the space containing the fluid. The first term in the right side of the equation is the complete pressure force over the entire surface of the fluid. The second term in the right side is the shearing force, i.e. complete reaction of all the solid elements against the shear stress distribution of the fluid over them. The third term is the total body force exerted on the fluid.
The first term in the left side can be written as
where the first term in the right side of Eq. (503) is the time rate of change of the momentum of the whole fluid as a lump in free space.
The surface of the fluid is confined to the surfaces of the solid elements. Therefore, the second term in the left side of Eq. (502) vanishes
Then summing the momentum Eq. (501) for all the solid elements with Eq. (502) for the fluid gives
Applying Newton's third law for interaction between the solid elements and their interaction with the fluid yields
Thus the momentum equation of the solid-fluid body must be written
In Eq. (509) the term in the left side, which is the time rate of change of the total of the momentums of all the elements of the solid-fluid body in free space, must be equal to the total force acting on the solid-fluid body to accelerate it in free space; the second and third terms in the right side represent the total of external forces acting on the solid-fluid body. Therefore, the first term in the right side must be a force that the solid-fluid body acts on itself due to unsteady flow fluctuations of the fluid. We denote this force by {right arrow over (F)}s, i.e.
Substituting Eq. (501) for the time rate of change of the momentum of each solid element in Eq. (509) gives
From Eqs. (510) and (511) we obtain
Then Eqs. (509) and (512) allow us to formulate the following
SELF_ACTION PRINCIPLE: A solid-fluid body except external forces is acted upon by a self-action force, {right arrow over (F)}s, equal to the sum of the time rate of change of the momentum of the whole fluid as a lump in free space and the total force due to the pressure and shear stress distributions of the fluid over the surfaces of its solid elements reduced by the force due to its body force, i.e.
We see that the self-action principle is equivalent to the momentum Eq. (509). Let us denote the relative velocity of ith solid element inside the solid-fluid body by {right arrow over (V)}i, that is {right arrow over (V)}i={right arrow over (ν)}i−{right arrow over (ν)} and call the value mi{right arrow over (V)}i its relative internal momentum. Then the momentum Eq. (509) can be written as
From Eqs. (512) and (514) we obtain the momentum equation of the solid-fluid body in the form
where
is the total mass of all the solid elements of the solid-fluid body.
In order to assert the existence of the self-action force it is sufficient to consider a simple example described below.
Suppose a solid-fluid body is a hermetically sealed cylindrical solid chamber filled up with a fluid. Its cross-section area and length are A and l respectively. The cylindrical chamber contains no internal solid element. The external force, {right arrow over (F)}1(e), acting upon the chamber and the body force, {right arrow over (f)}, of the fluid are constant and have the same direction along its generatrix that lies on x-axis. The body force is uniform and the fluid is incompressible.
It is obvious that the shear stress is absent, {right arrow over (F)}1(τ)=0. The pressure along x-axis, i.e. the generatrix of the cylindrical chamber, can be found from the equation of fluid in relative equilibrium, that is
where ρ is the density of the fluid and a is the component of the acceleration of the cylindrical chamber in the direction of x-axis. Integrating the equation along the generatrix from 0 to l gives
pl−p0=−lρa (517)
where p0 and pl are the pressures of the fluid at the two ends of the cylindrical chamber.
Then the total force in the direction of x-axis due to the pressure distribution over the surfaces of the cylindrical chamber is
{right arrow over (F)}1(p)=îA(pl−p0)=−Alρ{right arrow over (a)}=−m0{right arrow over (a)} (518)
where î is the unit vector of x-axis.
Putting the total force {right arrow over (F)}1(p) due to the pressure distribution over the surfaces of the cylindrical chamber and the body force {right arrow over (f)} of the fluid into Eq. (513) gives the self-action force of the cylindrical chamber in the direction of x-axis
Eq. (519) shows that the self-action force of the cylindrical chamber always exists except the case of absence of the fluid or its body force. By analogy, it is easy to find the self-action force of solid-fluid bodies containing no internal solid element and having other shapes of their solid chambers. The above class of solid-fluid bodies is the class of simplest ones, since they contain no internal solid element. For solid-fluid bodies containing internal solid elements their self-action force can be increased very strongly due to interaction between their internal solid elements and fluid. The examples of solid-fluid bodies containing internal solid elements are the mobile objects presented in this invention. The application of the self-action principle to analysis of their dynamics will be considered after establishment of the relationship of the self-action principle with Newton's laws of motion and the conservation law for momentum based on Newton's laws.
It is obvious that the existence of the self-action force has disproved Newton's second law for solid-fluid bodies, since the law ignores their self-action force. For illustration of the breakdown of Newton's second law we consider again the solid-fluid body of the above example, i.e. the cylindrical chamber. We now define the acceleration of the cylindrical chamber by using the momentum Eq. (515). The last term in the right side of Eq. (515) equals to zero, since the cylindrical chamber contains no internal solid element. Then putting the total force due to the pressure distribution of the fluid over the surfaces of the cylindrical chamber and the external force acting upon the chamber into Eq. (515) yields
m1{right arrow over (a)}=−m0{right arrow over (a)}+{right arrow over (F)}1(e) (520)
Hence we obtain
Formula (521) shows the true acceleration of the cylindrical chamber.
If the self-action force of the cylindrical chamber was ignored and its acceleration was defined by Newton's second law, its Newtonian acceleration, {right arrow over (a)}N, would be
Comparing the true acceleration {right arrow over (a)} of the cylindrical chamber with its Newtonian acceleration {right arrow over (a)}N we see that, in general, the Newtonian acceleration differs from the true acceleration except the case of absence of the fluid or its body force.
The breakdown of Newton's second law implies the breakdown of Newton's first law for solid-fluid bodies, since the first law is a consequence of the second one.
The breakdown of Newton's second law implies also the breakdown of Newton's third law for solid-fluid bodies, since under the action of an interactive force, {right arrow over (F)}±, between two solid-fluid bodies their resultant forces, {right arrow over (F)}1 and {right arrow over (F)}2, differ from each other due to the difference between their self-action forces, which depend on their structure, that is {right arrow over (F)}1={right arrow over (F)}+{right arrow over (F)}1s and {right arrow over (F)}2=−{right arrow over (F)}+{right arrow over (F)}2s imply {right arrow over (F)}1≠−{right arrow over (F)}2 if {right arrow over (F)}1s≠−{right arrow over (F)}2s. For illustration of the breakdown of Newton's third law we consider the interaction between two solid-fluid bodies, each of which is the cylindrical chamber described in the above example. We denote the masses of the fluid and cylindrical chamber of the first solid-fluid body by m10 and m11 respectively, and the second solid-fluid body by m20 and m21, respectively. Then their body forces are
Using formulae (519), (523), and (524) we obtain the self-action forces of the solid-fluid bodies
Formulae (525) and (526) show that in general {right arrow over (F)}1s≠−{right arrow over (F)}2s except the special case when
Thus we have seen that all Newton's laws of motion have been broken down for solid-fluid bodies, although the laws were applied to description of the dynamics of their solid elements and fluid particles in the conclusion of the momentum equation and self-action principle of a solid-fluid body. In other words, Newton's laws of motion are satisfied for individual solid elements and fluid particles of a solid-fluid body, but they are broken down in the whole solid-fluid body due to solid-fluid interaction. Therefore, it is necessary to correct Newton's laws of motion for the sake of unifying the fundamentals of mechanics.
When a solid-fluid body moves in free space, only its external momentum can be watched from the outer, whereas its internal can be not. Therefore, we must differ them from each other. Its external momentum is the value
Since {right arrow over (V)}i and {right arrow over (V)} are relative velocities of the internal solid elements and fluid particles inside the solid chamber respectively, the internal momentum of the solid-fluid body can be defined as the value
Then the momentum Eq. (514) can be written as
The momentum Eq. (530) differs from Newton's second law only in the presence of the internal momentum {right arrow over (p)}int. Therefore, Eq. (530) allows us to formulate the following
GENERALIZED NEWTON'S SECOND LAW: The time rate of change of the total of external and internal momentums of a solid-fluid body is directly proportional to the total of external forces acting on it and takes place in the direction of the total force.
We see that the self-action principle and generalized Newton's second law are equivalent, since both of them are equivalent to the momentum equation of the solid-fluid body.
If the external momentum {right arrow over (p)}ext is constant, then from Eq. (530) we have
Eq. (531) allows us to formulate the following
GENERALIZED NEWTON'S FIRST LAW: Every solid-fluid body continues in its state of rest or uniform motion in a straight line if the total of external forces acting on it equals to the time rate of change of its internal momentum.
We notice that the sense of the interactive force in Newton's third law remains correct for solid-fluid bodies only if Eq. (530) or the generalized Newton's second law is applied to their dynamics. Therefore, we can formulate the following
GENERALIZED NEWTON'S THIRD LAW: Whenever one solid-fluid body exerts a certain force on a second solid-fluid body, the second body exerts an equal and opposite force on the first and the time rate of change of the total of external and internal momentums of either body obeys the generalized Newton's second law.
We see that the above generalized Newton's laws of motion are consequences of the self-action principle or momentum equation of a solid-fluid body. We notice that the original Newton's laws of motion are special cases of the generalized ones when the fluid is absent in bodies or their total internal momentum is constant. Now the reason of the breakdown of the original Newton's laws of motion for solid-fluid bodies is clear. Isaac Newton in his famous Principia, published in 1687, stated the laws of motion only for (absolutely) solid bodies. The condition of the (absolutely) solid state of the bodies allowed Newton to consider them as material points and ignore their internal momentums. From the Newton's times up to now his laws have been applied to any body with the neglect of its internal momentums. The self-action principle has discovered the existence of the time rate of change of the internal momentums of solid-fluid bodies and naturally returned them to the fundamental laws of motion. Therefore, the self-action principle does not contradict Newton's laws of motion, but has naturally generalized them for a wider class of bodies by including the internal momentums of the bodies in the laws. In other words, the mechanics of solid-fluid bodies is a natural generalization of Newton's mechanics of solid bodies.
One of the important consequences of the original Newton's laws of motion is the conservation law for momentum. For solid-fluid bodies its counterpart can be obtained from Eq. (530). If the total of external forces vanishes from Eq. (530) we have
Eqs. (532) and (533) allow us to formulate the following
CONSERVATION LAW FOR MOMENTUM OF A SOLD_FLUID BODY: If the total of external forces is zero, the total of external and internal momentums of a solid-fluid body is conserved or the time rate of change of its external momentum is equal and opposite to the time rate of change of its internal momentum.
We again see that the conservation law for momentum of a solid body based on the original Newton's laws of motion is a special case of the conservation law for momentum of a solid-fluid body when its fluid is absent or its total internal momentum is constant. The conservation law for momentum of a solid-fluid body is also a consequence of the self-action principle or momentum equation of a solid-fluid body. Therefore, the self-action principle does not contradict the conservation law for momentum of a solid body based on the original Newton's laws of motion, but has naturally generalized it for a wider class of bodies by including the internal momentums of the bodies in the law.
We now can apply the self-action principle or its consequences to the correct analysis of mobile object 40. The symbols for the pressures used in the analysis are the same as shown in
It is obvious that the force due to the pressure and shear stress distributions over the side surface of generator chamber 48 vanishes. The forces due to the pressure distributions p5 and p6 over the internal and external side surfaces of circumferential tube 68 respectively also vanish due to their symmetry through the axis of shaft 56. Suppose when rotor 54 is at rest the pressure, p0, density, ρ0, temperature, T0, and total mass, m0, or volume, v0, of the gas in generator chamber 48 are known. We assume that when rotor 54 rotates with angular velocity ω the gas exhausted out of the rotor is compensated momentarily and the clearance between open bottom 72 and the upper surface of disk-stator 52 is such small that the gas inside rotor 54 can be considered almost as in relative equilibrium. In that case the pressure equation of the gas inside rotor 54 is
where the positive direction of r is taken outward from the axis of shaft 56. Solving Eq. (534) gives
Eq. (535) shows that the pressure inside rotor 54 depends not only on angular velocity ω, but also the pressure that is supported at the shaft inside rotor 54, i.e. P2(0).
The gas mass, mr, inside rotor 54 can be found by the integral
where Rr and h are the radius and height of the rotor respectively. The integral gives
In the above integral and hereafter we ignore the radius of the shaft because of its smallness. Therefore, the above integral is taken from zero, but not from the radius of the shaft.
When the rotor rotates, the gas mass, m, outside the rotor is
Then the average density of the gas outside the rotor is
where
is the volume of the gas.
If q is the coefficient of compensation of the gas inside rotor 54 at the shaft, the pressure p2(0) at the shaft is
p2(0)=qp=pρRT0 (539)
Solving the system of Eqs. (537)-(539) we obtain
Since m0=ρ0ν0, p0=ρ0RT0, and p=ρRT0, we have
We suppose that the upper surfaces of disk 70 and disk-stator 52 are such smooth that the gas flows over them can be considered as inviscid. The force due to the pressure distribution over the surfaces of the dividing walls must be zero, since the gas inside rotor 54 is in relative equilibrium. Then according to Eq. (513) the self-action force of mobile object 40 is
For calculation of the force {right arrow over (F)}(p
d{right arrow over (F)}(p
where {circumflex over (k)} is the unit vector of z-axis, which coincides with the axis of the shaft of the rotor.
We suppose the process is adiabatic, i.e. we do not provide or extract heat from the mobile object. Then we can use the energy equation and isentropic relationship for isentropic calorically perfect gas flows
where p and T0 are the pressure and temperature of the gas above the ring of radius r, and V1(r)=ωr. From Eqs. (544) and (545) we obtain
Substituting formula (546) for p1(r) in the right side of Eq. (543) gives
Summing the increments d{right arrow over (F)}(p
From the integrand of Eq. (548) we see that if
we can apply the binominal coefficients for the integrand. Taking the four fist coefficients gives
The integral yields
For the force acting on the infinitesimal ring of width dr and inner radius r of the lower surface of top disk 70 due to pressure p2 we have
d{right arrow over (F)}(p
Replacing p2(r) in Eq. (552) with expression (535) together with condition (539) gives
Then the total aerodynamic force acting on the lower surface of top disk 70 is defined by summing the increments d{right arrow over (F)}(p
The integral yields
{right arrow over (F)}(p
Further, the force acting on the infinitesimal ring of width dr and inner radius r of the upper surface of disk-stator 52 due to pressure p3 is
d{right arrow over (F)}(p
Since the disk-stator is fixed, the relative velocity of the gas over its upper surface can be defined as V3(r)=ωr2 Moreover, the pressure above the ring of radius r of its upper surface must be p2(r). Then by analogy to Eqs. (544)-(546) we obtain
Putting p2(r) from Eq. (535) and condition (539) into Eq. (557) gives
Substituting Eq. (558) into Eq. (556) gives
Summing the increments d{right arrow over (F)}(p
If condition (549) is satisfied the integrand of Eq. (560) can be expanded by applying the binominal coefficients, we obtain
Integrating the right side of Eq. (561) by parts we obtain
Finally, the force due to the pressure acting upon the lower surface of disk-stator 52 is
{right arrow over (F)}(p
We now determine the acceleration of mobile object 40 by putting the forces into Eq. (515). The last term in the right side of the equation vanishes because all the internal solid elements of the mobile object, i.e. their centers of mass, are stationary in relation to generator chamber 48. Then from Eq. (515) we obtain
where {right arrow over (F)}(e) is the total external force acting on the solid elements of the mobile object.
Substituting formula (565) for the acceleration a in Eq. (542) yields
In particular, when mobile object 40 is acted upon by a gravitational force, the body force of the gas, {right arrow over (f)}, equals to the acceleration of gravity, {right arrow over (f)}={right arrow over (g)}, and the total external force acting on its solid elements equals to their total mass multiplied by the acceleration, {right arrow over (F)}(e)=M{right arrow over (g)}. Then Eq. (565) becomes
and Eq. (566) becomes
Eq. (568) has proved that the self-action force of solid-fluid body 40 is defined by the pressure distributions over the lower and upper surfaces of top disk 70 and disk-stator 52. Moreover, since m0<<M, i.e. the mass of the gas is very small in comparison with the total mass of the solid elements, the term
in Eq. (568) can be neglected. Then from Eq. (568) we obtain the formula for calculation of the self-action force of solid-fluid body 40
where {right arrow over (F)}(p
For illustration we suppose that mobile object 40 is filled with air. Then we have γ=1.4 and Cp=1004.5 J/kg.K. Assume that the temperature and pressure of the air at rest in mobile object 40 are given by the values T0=188K and p0=1.01×105 N/m2, i.e. it equals to the pressure of the atmosphere at sea level. Putting the values of T0 and Cp into unequalness (549) yields the condition for validity of Eqs. (551) and (562) for {right arrow over (F)}(p
ΩRr<5800 (570)
where Ω is the angular velocity of rotor 54 in rounds per minute (r/min). The coefficient of compensation is chosen equal to unit, q=1. The volume of generator chamber 48 is 2 m2 and the height of rotor 54 is 0.5 m. The values of the self-action force of mobile object 40 calculated by formula (569) for some values of the angular velocity and radius of rotor 54 are presented in table A. In the table the angular velocity is measured in r/min, the radius in meters, and the self-action force in Newtons.
In table A we see that force generator 42 with a relatively small radius (not greater than 1 m) of its rotor and at a not very high angular velocity (not greater than 5000 r/min) can produce a very large lift. Those skilled in the art know that a lift device of other type (rotor of airfoil blades, lift disk, etc. . . . ) with the same sizes can produce a much smaller lift. The reason is that the increases in relative velocity of the gas on the lower and upper surfaces of a lift device of other type are almost the same when its radius or angular velocity increases. In contrary, when the radius or angular velocity of the force generator increases only the relative velocity on its upper surfaces increases, since the gas on its lower surfaces is in relative equilibrium. Therefore, the force generator produces the
maximum difference between the pressures of the gas acting on its lower and upper surfaces, i.e. maximum lift.
The values of the self-action force presented in table A were calculated for the fixed pressure at rest p0=1.01×105 N/m2 in generator chamber 48. Formulae (569), (548), (560), and (564) together with formula (541) show that the self-action force of mobile object 40 is proportional to the pressure p0. Therefore, the self-action force of mobile object 40 can be increased further due to increasing the pressure p0 in generator chamber 48.
For the test of the self-action force produced by mobile object 40 its experimental model with the force generator having the rotor of 0.2 m radius and 0.15 m height has been built. An electrical motor of 3 kW was used for driving rotor 54. The self-action force was measured at angular velocity 3000 r/min. The measurement of the self-action force was implemented by a weighing-scale that measured the weight of the mobile object at rest and at angular velocity 3000 r/min. The volume of the generator chamber was 0.1 m3, 0.2 m3, and 0.5 m3. For the first experiment some holes of the disk-stator were made for creation of the natural passages of air without any compensating gas means. The produced self-action force oscillated between 200 Newtons and 300 Newtons. The produced self-action force was almost the same for the volume 0.1 m3, 0.2 m3, and 0.5 m3 of the generator chamber. In the second experiment the volume of the generator chamber was 0.5 m3, the angular velocity of the rotor was 3000 r/min, different fans in a fan duct were used for the air compensation for the sake of reduction of the amplitude of oscillation of the self-action force. With the more suitable fans the produced self-action force oscillated slightly around 300 Newtons.
For testing the force generator alone, the generator chamber of the above experimental mobile object was removed. The lift of the force generator oscillated also slightly around 300 Newtons, that is it remains almost the same as in the case of the closure of the force generator in the generator chamber. For another test a force generator having a rotor of 0.5 m radius and 0.45 m height has been built. An electrical motor 1.3 kW was used for driving its rotor. The lift of the force generator was measured at angular velocity 1400 r/min. A compressor was used for the air compensation. The lift of the force generator oscillated slightly around the value 2670 Newtons.
So far we have considered the dynamics of the mobile object with one force generator. In general, each mobile object can include a plurality of the force generators. Then its self-action force is the total of the forces produced by all of its force generators. For example, if the mobile object comprises L force generators and the mass of the gas is ignored, its self-action force is
where {right arrow over (F)}sj is the force produced by jth force generator. Then the acceleration of the mobile object is
where M is the total mass of all the solid elements of the mobile object and {right arrow over (g)} is the gravitational acceleration.
If mobile object 40 operates in the atmosphere and the working gas is the air at the atmospheric pressure, the earth's atmosphere can serve as a generator chamber of mobile object 40. In that case shell 100 may be removed or the generator chamber needs not to be pressurized. In
From the above consideration of operation of mobile object 40 and mathematical analysis of its dynamics we notice that force generator 42 produces the maximum difference between the pressures of the gas acting on its lower and upper surfaces, i.e. maximum lift, due to the special mutual structure of rotor 54 and disk-stator 52, which support the gas in relative equilibrium inside the rotor and under the disk-stator. For supporting the gas in relative equilibrium rotor 54 includes the two basic physical features that distinguish from the rotors of other lift devices. The first distinguished physical feature of rotor 54 is the rotary shell that is constituted of circumferential tube 68 and top disk 70 and has open bottom 72. The second distinguished physical feature of rotor 54 is a plurality of dividing walls that constitute a means supporting the gas in relative equilibrium inside the rotary shell during rotation of the shaft of rotor 54 when open bottom 72 is closed by disk-stator 52. The disk-stator is a stationary means that closes open bottom 72 for implementation of two functions. The first function of disk-stator 52 is to constrain the gas in the rotary shell during rotation of the shaft of rotor 54. The second function of disk-stator 52 is to produce the maximum difference between the pressures of the gas acting on its lower and upper surfaces, i.e. to support the gas on its lower surface in relative equilibrium. Thus disk-stator 52 is another distinguished physical feature of force generator 42 and together with rotor 54 constitute a mutual pair in the meaning of their geometric structure. The basic feature of the geometric structure of the mutual pair of rotor 54 and stator 52 is the division of the space bounded by the rotor and disk-stator into separate sections such that the separate sections rotate together with rotor 54 and the uncovered lower edges of dividing walls 76 skim the upper surface of disk-stator 52. The mutual structure of rotor 54 and stator 52 makes the working gas in the space bounded by the rotor and stator rotate together with rotor 54 and sweep over the upper surface of disk-stator 52. In other words, in the mutual structure the rotor is an accompanying gas means for accompanying a gas volume sweep over a part of the surface of the disk-stator. Therefore, the geometric structure of the mutual pair of the rotor and disk-stator can be modified provided they have the basic feature of the geometric structure. For example, the mutual pair of rotor 54 and disk-stator 52 may be replaced by the mutual pair of a rotor 102 and a stator 104 illustrated in
From the illustrated above pairs of rotor and stator we notice that each pair of a rotor and a stator can be constructed by the following way. The rotor includes a shaft, a shell, and a plurality of dividing walls. The shaft has bearing supporters being secured to the generator frame. The dividing walls extend from the shaft and an upper part of the surface swept by the edges of the dividing walls due to their rotation about the axis of the shaft is covered by the shell (the upper part may include the full outer edges of the dividing wall and even a apart of the bottom edges). The shaft may be separate and the rotor has an assembling member for assembly of the shaft. The surface swept by the uncovered part of the edges of the dividing walls due to their rotation about the axis of the shaft forms an open rotary surface of the rotor. The stator is a rigid member and has a fitting surface, which is a part of the surface of the stator that fits the open rotary surface of the rotor. The stator is secured to the generator frame and located under the rotor. The clearance between the open rotary surface of the rotor and the fitting surface of the stator is such small that the space bounded by the rotor and stator is divided into separate sections rotating about the axis of the shaft and the uncovered part of the edges of the dividing walls skims the fitting surface of the stator to accompany the working gas filling the space bounded by the rotor and the stator during rotation of the rotor. Whereby the working gas filling the space bounded by the rotor and the stator rotates together with the rotor and sweeps over the fitting surface of the stator during rotation of the rotor. For example, in the mutual pair of rotor 102 and stator 104 illustrated in
In
We notice that if disk-stator 52 of force generator 42 of mobile object 40 of
In operation, rotor of blades 170 is driven from engine 182 through gearbox 184. Then the aerodynamic force or the lift created by rotor 170 can get a sufficiently large value due to the high pressure in generator chamber 172 and high angular velocity of rotor 170. That force acts on the whole body of mobile object 168 through the shaft, mechanical joints, fasteners, supporters, and structural frame of the mobile object. Thus mobile object 168 generates its self-action force that also does not depend on the outer environment surrounding the mobile object. Mobile object 168 distinguishes from conventional helicopters by the independence of its self-action force from outer environment and the possibility of the operation of rotor 170 at high pressure that allows reducing the size of its blades and increasing its angular velocity.
We now apply the self-action principle presented earlier to the correct analysis of the dynamics of mobile object 168.
Since the gas is compressible we write its equation in relative equilibrium in the form
The solution of the equation is
where p1 is the pressure of the gas on the floor of generator chamber 172. If p0 is the density of the gas at rest, then due to the conservation of mass we have
where l is the average height of generator chamber 172. From Eq. (575) we have
Substituting formula (576) for p1 in Eq. (574) yields
From Eq. (577) we obtain the difference in pressure between the ceiling and floor
p2−p1=−lρ0a (578)
Then the force due to the pressure distributions over the ceiling and floor is
{right arrow over (F)}(p
It is obvious that the total force due to the pressure and shear stress distributions over the walls of mobile object 168 vanishes. The force due to the pressure and shear stress distributions over the surfaces of blades of rotor 170 is its aerodynamic lift, {right arrow over (L)}R. Then according to Eq. (513) the self-action force of mobile object 168 is
{right arrow over (F)}s=m0{right arrow over (a)}+{right arrow over (F)}(p
The last term in the right side of Eq. (515) vanishes, since the center of mass of rotor 170 is at rest in relation to generator chamber 172. Therefore, putting the corresponding forces into Eq. (515) gives
M{right arrow over (a)}={right arrow over (F)}(p
where {right arrow over (F)}(e) is the total external force acting on all the solid elements of the mobile object.
From Eq. (581) we obtain the acceleration of mobile object 168
In particular, when mobile object 168 is acted upon by a gravitational force, the body force of the gas, {right arrow over (f)}, equals to the acceleration of gravity, {right arrow over (f)}={right arrow over (g)}, and the total external force is {right arrow over (F)}(e)=M{right arrow over (g)}. Then Eqs. (580) and (582) become
Formula (583) shows that the self-action force of mobile object 168 is almost equal to the lift {right arrow over (L)}R of rotor 170, since the mass m0 of the gas is very small in comparison with the mass of the mobile object and the gravitational force acting on the gas is very small in comparison with the lift of the rotor.
For testing the self-action force of mobile object 168, the cross-section of the blades of rotor 170 was chosen such that the lift of rotor 170 was created only by the difference between the pressures of the gas acting on the lower and upper surfaces of the blades and the volume of the gas flowing downward during rotation of the rotor was as small as possible. With such cross-section of the blades, the self-action force of mobile object 168 was almost equal to the lift of rotor 170 when the height of generator chamber 172 was greater than three times of the radius of the rotor. When the height of generator chamber 172 decreased, the self-action force of mobile object 168 also decreased and was less than the lift of rotor 170.
Formulae (583) and (584) show that the self-action force and acceleration of mobile object 168 are fully defined by the lift {right arrow over (L)}R of rotor 170 in the case of absence of gravitational force. Those skilled in the art know that the lift of a lift device increases when the pressure of the working gas increases. Therefore, the self-action force of mobile object 168 can be increased as many times as desirable by increasing the pressure of the gas inside generator chamber 172.
Mobile object 40 can accompany a body or a vehicle. Then the motion direction of the vehicle can be controlled by controlling the direction of the shaft of the force generator of the mobile object. In order to cancel the reactive moment of the rotor of the force generator it is desirable to install in the generator chamber two identical force generators rotating in opposite directions. The value of the force generated by each force generator can be controlled by controlling the angular velocity of its rotor due to regulating the angular velocity of its driving engine and a brake (not shown) for braking its rotor in necessary situations. In general, each vehicle can be equipped with a plurality of the force generators and a space inside the vehicle can be used as a generator chamber of its force generators.
In operation, force generators 192 and 194 are driven from engines 196 and 198 through mechanical transmission means 197 and 199 respectively. The angular velocity of engines 196 and 198, therefore and force generators 192 and 194, are controlled by a control system (not shown) mounted in the cockpit (not shown) of aircraft 190. During take-off force generators 192 and 194 lift aircraft 190 to a necessary height before starting its horizontal motion. During flying force generators 192 and 194 may be at rest or used to increase the height of the fly if it is necessary. During landing the force generators are controlled to provide a smooth vertical landing.
Mobile object 188 may be also equipped with force generators mounted horizontally (with horizontal orientation of their axes) for propulsion. In
The use of force generators for lifting and landing of a conventional aircraft allows not only to increase its safety in flying, but also to remove its wings. If the wings of aircraft 190 are removed, mobile object 188 can fly at any altitude that does not depend on its speed. In that case either a conventional propulsion mechanism (not shown) or force generators 200 and 202 are used for propulsion.
Mobile object 188 is an aircraft of the combination of the force generator's technology with the conventional technology.
In operation, force generators 212, 214, 216, 218, 220, and 222 are driven from engines 228, 230, 232, 234, 236, and 238 through mechanical transmission means 229, 231, 233, 235, 237, and 239 respectively. The angular velocities of engines 228, 230, 232, 234, 236, and 238, therefore and force generators 212, 214, 216, 218, 220, and 222 are controlled by a control system (not shown) mounted in a cockpit 242 of aircraft 210. Force generators 212, 214, 216, and 218 are used for lifting and landing. Force generators 220 and 222 are used for propulsion. Mobile object 208 yaws by controlling horizontally mounted force generators 220 and 222. Controlling the difference between the forces generated by force generator 220 and force generator 222 creates a necessary moment to yaw mobile object 208 to the right or to the left. Mobile object 208 can also yaw by controlling rudder 240. Mobile object 208 pitches by controlling vertically mounted force generators 212, 214, 216, and 218. Controlling the difference between the total force generated by fore force generators 212 and 214 and the total force generated by backward force generators 216 and 218 creates a necessary moment to pitch mobile object 208 upwards or downwards. Mobile object 208 rolls by controlling vertically mounted force generators 212, 214, 216, and 218. Controlling the difference between the total force generated by right force generators 212 and 216 and the total force generated by left force generators 214 and 218 creates a necessary moment to roll mobile object 208 to the right or the left. Since the air density does not influence on the operation of the force generators, mobile object 208 can fly at any altitude.
A mobile object being a conventional vehicle such as an automobile, a train, a ship, or a submarine can be also equipped with the force generators like the conventionalaircrafts equipped with the force generators illustrated in
In operation, force generators 272, 274, 276, and 278 are driven from engines 284, 290, 296, and 302 through mechanical transmission means 288, 294, 300, and 306 respectively or electrical motors 286, 292, 298, and 304 through mechanical transmission means 288, 294, 300, and 306 respectively. Force generators 280 and 282 are driven from engine 308 or electrical motor 310 through mechanical transmission means 312. The angular velocities of engines 284, 290, 296, 302, and 308 or electrical motor 286, 292, 298, 304, and 310, therefore and force generators 272, 274, 276, 278, 280, and 282 are controlled by control unit 344. Force generators 272, 274, 276, and 278 lift mobile object 244 in the direction of the vertical axis of the mobile object. Force generators 280 and 282 thrust mobile object 244 in a direction perpendicular to the vertical axis of the mobile object. The instant direction of the thrusting force of force generators 280 and 282 is defined by the instant turning angle of turntable 320, which is controlled by control motor 322. Then mobile object 244 can implement any translation motion in space by combination of the lifting and thrusting forces. Mobile object 244 maneuvers by controlling the forces generated by force generators 272, 274, 276, 278, 280, and 282 to create necessary moments. Mobile object 244 rolls about the axis of symmetry between the pair of force generators 272 and 274 and the pair of force generators 276 and 278 by creation of the difference between the total force generated by force generators 272 and 274 and the total force generated by force generators 276 and 278. Mobile object 244 rolls about the axis of symmetry between the pair of force generators 272 and 278 and the pair of force generators 274 and 276 by creation of the difference between the total force generated by force generators 272 and 278 and the total force generated by force generators 274 and 276. Mobile object 244 rolls about the axis of symmetry between force generators 272 and 276 by creation of the difference between the force generated by force generator 272 and the force generated by force generator 276. Mobile object 244 rolls about the axis of symmetry between force generators 274 and 278 by creation of the difference between the force generated by force generator 274 and the force generated by force generator 278. Thus mobile object 244 can implement almost any maneuver in any direction in space by controlling force generators 272, 274, 276, 278, 280, and 282, and turntable 320. When mobile object 244 flies at very high altitude or in cosmos, solar energy converted to electrical energy by photovoltaic panels 270 can be used for powering electrical motors 286, 292, 298, 304, and 310. Particularly, in cosmos mobile object 244 can continue accelerate by using solar energy or universe energy up to desirable velocity and the fuel on board can be saved for emergencies. Since the value and direction of the self-action force can be controlled and do not depend on the air density, mobile object 244 can come out to the cosmos and return into the atmosphere smoothly.
Mobile object 244 shown in
If a mobile object equipped with the force generators flies at a low altitude near the earth surface and its volume is desired to be as small as possible for a given passenger space, the number of the equipped force generators may be reduced by adding other members.
In operation, force generators 370 and 372 are driven from engines 374 and 378 through mechanical transmission means 376 and 380 respectively. Hydraulic jacks 390 and 392 raise or lower the edge of rectangular frame 382 jointed with their tops to give a desirable angle of the axes of force generators 370 and 372 relative to the horizontal plane. Then the total force created by force generators 370 and 372 is resolved into the vertical component and horizontal component. The vertical component is the lift of mobile object 346 and the horizontal component is the propulsion of the mobile object. Thus mobile object 346 can lift, hover in the air, and fly forward or backward by controlling the operation of force generators 370 and 372 and hydraulic jacks 390 and 392. Mobile object 346 yaws by controlling rudder 354. Mobile object 346 rolls by creating a difference between the lifting forces generated by force generators 370 and 372. If a lower part of the skin of body 348 is sealed, mobile object 346 can sail on water surface. Mobile object 346 runs on the ground by wheels 368. Thus mobile object 346 can take-off, hover in the mid-air, fly forward and backward, land, run on the ground, and sail on the water surface.
For increasing flying speed mobile object 346 may be further equipped with an additional propulsion mechanism that may be a horizontally mounted force generator (not shown) or a conventional propulsion mechanism (not shown).
From the foregoing, it will be seen that the present invention provides a new generation of vehicles. The distinguished advantage of the new vehicles is their ability to generate self-action forces, which do not depend on outer environment surrounding them. The advantage is achieved by equipping the vehicles with a plurality of force generators, which are principal components of the invention. The independence from outer environment makes the vehicles universal, much more flexible, and safer, and the infrastructure for their exploitation simpler and cheaper. The advantages of the force generators as propulsion mechanisms are their ability to be enclosed in any vehicle and generate very large forces from any source of energy, since any source of energy can be converted into rotational. The enclosure of the force generators makes the motion of the vehicles much more quiet than that of the conventional ones due to ability of damping noisy down to minimum.
An aircraft equipped with the force generators can take-off and land vertically, hover in space, fly at any altitude being independent of speed of flying, and implement flexible maneuvers. The vertical take-off and landing makes the aviation transport systems much more flexible, simpler, safer, and cheaper.
A flying car equipped with the force generators can take-off and land vertically, hover in the mid-air, fly forward and backward, implement flexible maneuvers, run on the ground, and sail on the water surface. The size of the flying car can be made sufficiently small as an automobile. Therefore, the application of the flying car can solve the jam problem of the traffic system on the ground.
A flying saucer equipped with the force generators is a universal vehicle in the earth's atmosphere and in the cosmos. The flying saucer can accelerate in any direction, implement very complicated maneuvers, come out to the cosmos and return in to the atmosphere smoothly.
A spaceship, which may be the above flying saucer, can continue accelerate in cosmos up to desirable velocity by using the solar or universe energy.
An automobile, a train, and a ship equipped with the force generators can carry heavier loads or move faster.
A submarine equipped with the force generators can dive deeper and maneuver easier in the depth.
A town in cosmos can be constructed as large as desirable by using a large number of force generators.
Flying robots for different purposes can be made by using the force generator's technology.
Accordingly, the main objects and advantages of my invention are to provide vehicles with mechanisms which allow the vehicles to generate their self-action forces for starting, accelerating, lifting, landing, and moving in any direction in the air, cosmos, and water (if it is sealed) and on any ground surface and water surface (if the lower part of its body is sealed). The vehicles will make the mankind's transport system much more flexible, simple, cheap, and faster in both the earth's environment and universe.
