Description




BACKGROUND OF THE INVENTION




The present invention generally relates to a housing for a disk rotor propulsion turbine system. More specifically, the present invention relates to a housing for a disk rotor propulsion system having a generally wedge-shaped front end, an intake opening, and an outflow opening for use in a propulsion system as well as a method for using the same.




It is, of course, generally known to provide propulsion systems and housings that are designed to move a craft through a fluid medium. Moreover, it is generally known to provide pumps or engines that are designed for use with a plurality of disks stacked one atop another with minimal spacing therebetween. The disks, upon high speed rotation, provide an engine or motor with high power output using relatively low amounts of input energy.




Known disk rotor systems are generally used as pumps. The typical housing for a disk rotor system is generally cylindrically-shaped with an inflow opening along a longitudinal axis of the cylinder and an outflow tube that is perpendicular to the longitudinal axis of the cylinder. As the disks spin, centrifugal forces draw the material from the opening at the axis of the disks to a periphery of the disks. The outflow opening generally allows the material to be expelled from the housing. These pumps are generally stationary systems and are not designed or shaped to move through the material being pumped.




It is known, for example, in U.S. Pat. No. 4,768,920, to provide a housing having a generally cylindrical chamber formed by a pair of circular endwalls connected by a peripheral wall within which is mounted a disk rotor system. The housing includes an inlet into the chamber and an outlet from the periphery of the chamber. In operation, fluid, such as air or water, is introduced through the inlet port and directed into an axial opening of the system of disks. Rotation of the disks along with the viscosity of the fluid imparts a propulsive force thereto.




As fluid enters the disk system, fluid molecules attach to the disk surfaces to form a boundary layer. The boundary layer serves as a molecular buffer between the disk surface and the fluid contents. As the rotor is powered and the disks spin, the boundary layer attracts and drags along other layers of molecules through the centrifugal force. The dynamic force propels the fluid which is then expelled from the system of disks along the periphery of the disks through an output opening.




A need, therefore, exists for an improved housing for the disk rotor system to provide an efficient and low cost propulsion system capable of aerodynamic movement through a pumped medium.

DETAILED DESCRIPTION OF THE PRESENTLY PREFERRED EMBODIMENTS




The present invention generally relates to a housing for use in a device, such as a disk rotor propulsion system. Preferably, the propulsion system consists of a plurality of disks stacked one atop another and incorporated in the interior of the housing. The present invention further relates to a system that incorporates the housing of the present invention as well as a method of using the same.




Referring now to the drawings wherein like numerals refer to like parts,

FIG. 1

generally illustrates an embodiment of a housing


10


having a plurality of disks


12


incorporated therein. The plurality of disks


12


may be part of a propulsion system wherein the disks rotate at high speeds and a fluid such as air or water enters through an axial opening


14


in the center of the disks


12


and exits at a periphery


16


of the plurality of disks


12


. The structure of the plurality of disks and use thereof is well known in the art and is generally shown and described in U.S. Pat. No. 1,061,206 to Tesla, the disclosure of which is incorporated herein by reference in its entirety. The specific shape and design of the disks, however, is not limited to that shown in FIG.


1


.




The housing


10


has a wedge-shaped end


18


and a planar end


20


on opposite ends of the housing


10


. The wedge-shaped end


18


provides for streamlined motion as the housing


10


moves through a fluid, such as air or water.




Two sides


22


and


24


are provided on opposite sides of the housing


10


and generally define the specific shape of the housing


10


. The wedge-shaped end


18


has an edge


19


. At the first wedge-shaped end


18


, the two sides may have segments


25


,


27


that form an acute angle at the edge


19


of the wedge-shaped end


18


. The segments


25


,


27


may be disposed between the edge


19


and a point


26


. The two sides


22


,


24


may have additional segments


29


,


31


that extend substantially parallel to each other from the point


26


to a second point


28


. Further, segments


33


,


35


may be disposed between the second point


28


and the planar end


20


. The segments


33


,


35


may be angled slightly towards each other at the second point


28


. Top and bottom sides


30


,


32


may be disposed substantially parallel to each other and are perpendicular to the sides


22


and


24


. The edge


19


, the sides


22


,


24


, the top side


30


and the bottom side


32


define the shape of the housing


10


.




The housing


10


, however, is not necessarily limited to the specific construction heretofore described. Other shapes are contemplated and will be apparent to those skilled in the art.




An inflow opening


34


may be provided along the side


24


to allow a fluid, for example, to enter the housing


10


and flow through the propulsion system


12


. The opening


34


may be rectangularly shaped and provides a direct inlet to the axial opening


14


of the plurality of disks


12


. However, the shape of the inflow opening


34


is not necessarily limited to the shape set forth stated above. Differently shaped openings are contemplated by the present invention and will be apparent to those skilled in the art. A second opening (not shown) may be provided in the side


22


. The second opening may be identical to the first opening


34


but may be provided on an opposite side


22


of the housing


10


as compared to the first opening


34


. The second opening may also provide a direct inlet to the axial opening


14


of the plurality of disks


12


.




An outflow opening


36


may be provided in the planar end


20


to allow the fluid to exit the housing


10


. The outflow opening


36


may be rectangularly shaped; however, other shapes are contemplated that provide a direct outlet from the housing


10


.




Generally, as fluid enters the propulsion system


12


, a layer of fluid molecules attaches to a disk surface forming a boundary layer. The boundary layer serves as a molecular buffer between the disk and the fluid contents. As the plurality of disks rotate at high speed, the boundary attracts and drags along other layers of molecules through centrifugal force. The dynamic force propels the fluid between the disks


12


and out the periphery


16


of the plurality of disks


12


. The fluid is ejected forcefully from the housing


10


through the outflow opening


36


.




In use, the housing


10


may be submerged in a fluid, such as water. A motor or an engine


56


(generically shown in

FIGS. 2 and 3

) provides a drive to spin the plurality of disks


12


at high speed. Spinning the disks


12


at a high speed forcefully ejects fluid contained between the disks


12


out the periphery of the disks


16


and subsequently out of the housing


10


through the outflow opening


36


. More fluid may then be pulled through the intake opening


34


and subsequently forcefully ejected from the housing


10


through the opening


36


. This provides a propulsion to the housing


10


if the housing


10


is free-standing within the fluid. The wedge-shaped end


18


provides a streamlined shape so that the housing


10


may move efficiently through the fluid. Any such rotor or engine may be utilized to impart rotary motion to the plurality of disks


12


to cause the disks


12


to spin at a high speed.




Preferably the edge


19


, the sides


22


,


24


, the top side


30


, and the bottom side


32


form the outside walls of the interior compartment contained within the housing


10


that contains the plurality of disks. The housing


10


, however, may have a cavity


11


formed therein. The cavity


11


may be shaped in such a manner so as to provide a compartment for the plurality of disks


12


. The shape of the cavity


11


may provide a path for the forcefully ejected fluid to flow before exiting through the outflow opening


36


.





FIGS. 2 and 3

provide alternate embodiments


50


and


52


, respectively, of the present invention wherein the housing


10


is attached to a shaft


54


and a motor or engine


56


. The shaft


54


may be attached on the side


30


such that the axial opening


14


of the plurality of disks


12


are perpendicular to the drive shaft. Alternately, the housing


10


may be attached to the shaft


54


on the side


24


such that the axial opening


14


of the plurality of disks


12


may be disposed parallel to the shaft


54


. Other like positions for the shaft


54


may be utilized in this invention and will be apparent to those skilled in the art.




In use, the housing


10


with the plurality of disks


12


, the shaft


54


and the motor or engine


56


are provided attached to a craft (not shown), such as a boat or a submarine or other like vessel. Upon activation and rotation of the disks


12


within the housing


10


, fluid may be drawn within the housing


10


through the intake opening


34


and forcefully ejected through the outflow opening


36


. As the fluid is forcefully ejected from the housing


10


, the boat or submarine may be propelled through the fluid.




It should be understood that various changes and modifications to the presently preferred embodiments described herein will be apparent to those skilled in the art. Such changes and modifications may be made without departing from the spirit and scope of the present invention and without diminishing its attendant advantages. It is, therefore, intended that such changes and modifications be covered by the appended claims.
