The disclosure relates generally to rotary-winged vehicle systems and devices, and more specifically to rotary-winged systems with engines or engine components mounted within rotor blades of the rotary-winged system.
The 1930's and 40's were a very significant era for aerospace, e.g. Juan De La Cierva had already demonstrated his Autogyro and in the 1930's Harold Pitcairn brought it into commercial production. In August 1939 the first jet engine aircraft flew in Germany and a month later Igor Sikorsky flew the first helicopter.
As exciting as the developments were, each had its own fundamental limitations and significant research has not resolved these limitations. An autogyro is a rotary winged aircraft where the rotor is not powered directly. It cannot produce lift unless its rotor is first brought to speed by some drive mechanism that is then disconnected, and the craft is moving forwards or downwards. A helicopter has an engine inside the body of the vehicle which rotates the rotor through a shaft. The drive system often requires complex gearing. The pitch of the rotor blade can alter as it travels through the air allowing the helicopter take off vertically and maneuver in all directions. However, this in turn increases complexity and requires some method to counter torque, the force turning the body of the helicopter in the opposite direction to the rotor. Various systems exist such as having two counter rotating rotors but the commonest is having a tail rotor the pilot controls through a foot control.
Helicopters may be very difficult to fly and require significant training. Failure of the tail rotor is catastrophic. Even though it can take off vertically, a helicopter must achieve a certain height or forward velocity to “autogyro” in the event of engine failure. For this reason, many helicopter fatalities occur in the first 30 feet.
The development of the jet engine has driven significant improvements in materials, but fuel efficiency is still hampered by the different “ideal” speeds of the intake compressor and the exhaust turbine. Some of the energy in the thrust coming from the combustion chamber must be captured to drive the shaft that turns the compressor. To do so efficiently, the turbine must be rotating extremely fast as the air passing it is travelling close to the speed of sound but the compressor, linked directly by a shaft, would ideally rotate much slower so as to be able to compress and slow the incoming air. Due to the high temperatures and extreme RPM, only recently has a gearing system been developed to counter this. It reportedly increases the fuel efficiency by 15% but it two has significant limitations described in greater detail below.
There are other types of jet engines, but the RAMjet must first be travelling close to the speed of sound to operate and pulse jets, though simple in design, produce little thrust. Further discussion below relates to improvement of turbo jet engines only.
Conventional jet engines can be design-limited in function and geometries. For example, conventional turbine jet engines drive a compressor by way of a turbine shaft connected to a turbine, thereby creating compressors of cylindrical shape. Also, conventional jet engines physically couple the air intake portions with the exhaust portions, resulting in a cylindrical shape for most components, such as the combustion chamber. In addition, the rotational speed of the shaft and the centrifugal force created by the high RPM of both turbine and compressor require significant mechanical structure and this increases the weight of the engine.
Some rotary winged aircraft use jet engines to provide the necessary drive. The jet engines do not drive the rotor by providing direct thrust as they do in a fixed wing aircraft but are used to drive a second turbine that is connected to reduction gearing connected to the rotor.
What is needed are rotary-winged systems that provide improved performance and safety by incorporating designs that eliminate the need for torque control and employ alternate turbine jet engine designs. The disclosure provides a solution through mounting of one or more engine components within rotor blades of a rotary-winged system. In one embodiment, engines are mounted within the rotor blades, with exhaust ports positioned at the rotor blade tips. In another embodiment the jet engines are located on a cross bar connected to the rotor shaft. In another embodiment, the design includes an electrical generation system at the central spindle, this incorporates counter rotating rotors to compensate for the torque that may be created. In another embodiment, the engine of a rotary-winged vehicle includes a centrifugal compressor co-axially mounted with a spindle of the rotor blades. In one aspect, the compressor of one or more engines is decoupled from the engine turbine and electrically driven. In one aspect, the rotary-winged vehicle may be operated autonomously.

Reference will now be made in detail to representative embodiments. The following descriptions are not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined, for example, by the appended claims.
A perspective view of a conventional rotary-winged vehicle 10 of the prior art is provided as
In contrast, the disclosure presents embodiments of rotary-winged systems wherein one or more engine components, or complete engines, are mounted within an interior of rotor blades of a rotary-winged system. Such configurations provide a number of advantages which will be discussed below. The embodiments of the disclosure and associated features will be described with respect to
In one embodiment, engines are mounted within the rotor blades, with exhaust ports positioned at the rotor blade tips. In another embodiment, the engine of a rotary-winged vehicle includes a centrifugal compressor co-axially mounted with a spindle of the rotor blades. In one aspect, the compressor of one or more engines is decoupled from the engine turbine and electrically driven. In one aspect, the rotary-winged vehicle may be operated autonomously.
With attention to
The rotary-winged system 200 of
The prior art includes RAMjet engines, pulse jet engines, and various rocket engines at the tips of the rotor of a rotary wing craft. Such designs may eliminate the torque generated by the hub or in vehicle engines. The lack of torque is advantageous because, e.g., it eliminates the need for a tail rotor or other similar anti torque system. Many of the problems associated with rotary wing aircraft, including difficulty to control, relatively high noise, hazard to nearby individuals and mechanical failure, relate to the need for a tail rotor.
However, many existing designs to eliminate the tail rotor are limited by the increased drag associated with the tip engines, often preventing the rotor to autogyro and creating a significant safety concern. Other existing designs describe the use of an in-rotor pulse jet engine and “pressure jet” variants as an alternative to tip engines. However, none of the existing designs have ever been demonstrated as viable flight options. Pulse jets, and related variations, though very simple and light weight in design, produce too little thrust to create sufficient rotation and thus provide insufficient lift.
The disclosure uses modern micro turbo jet engines that can produce sufficient thrust without increasing the drag significantly. In one embodiment, the intake for the jet engine is directed toward the hub of the rotor, and the thrust vectors out of a shrouded exhaust, thus providing the necessary rotation but not increasing rotor drag. In another embodiment, the turbine and the shaft components are not present, thrust is vectored out from the rotor tip, and the rotation of the rotor drives a hub-based generator or mechanical drive that drives the compressor directly or electrically.

One or more rotor blades 210 comprise an engine 230 mounted within an interior of a rotor blade 210. In the cut-away depiction of a rotary-winged system 200 in
In the configuration of
In another embodiment, a four-bladed system 200 comprises a total of two engines 230, one at a rotor blade 210 at the 90-degree position and a second engine 230 at the opposite rotor blade 210 at the 270-degree position (i.e. the 9 o'clock position). The configurations of these two rotor blades 210, i.e. the rotor blades at the 90 degree and at the 270-degree position, would be identical and create a symmetrical arrangement.
Each rotor blade 210 that houses or contains an engine 230 comprises an air intake port 215 comprising an array or set of voids 216 or apertures configures to receive a fluid such as air. In the configuration depicted in
Engine 230 comprises a compressor 234, combustion chamber 235, set of stators 236, a turbine 237 engaged with a turbine shaft 238, and nozzle 233. In one embodiment, other than the relatively small size of the engine 230, the engine 230 of
The rotary-winged vehicle system 300 comprises a power generator 350, such as an electric power generator. The power generator 350, among other things, provides power to the compressor 334. Such a configuration may be termed an electrically-decoupled turbine engine design. In the configuration of
Note that an electrically-decoupled turbine engine design allows non-traditional designs for the combustion chamber because the combustion chamber is no longer driven by a rotating shaft (which results in combustion chambers of traditionally cylindrical shape). In contrast, an electrically-decoupled turbine engine design is not design driven to be of cylindrical shape, and thus may be optimized for other parameters, resulting in essentially any shape in addition to a cylindrical shape. In addition, such separation of intake, compressor, combustion chamber of varied geometry and variable location of the exhaust thrust can be applied to fixed wing as well as rotary wing designs.
Conventional centrifugal and co-axial turbo jet designs use a single shaft connecting the rear turbine to the forward compressor element. This shaft transfers a portion of the thrust captured by the rear turbine and converts the energy into rotary motion to drive the compressor. The intake air is compressed and sent to the combustion chamber to provide increased efficiency of combustion fundamental to the engines function.
Typically, approximately 25% of the energy in the exhaust thrust is captured and used to drive the compression phase. However, due to differences in the velocity of airflow at the intake and the exhaust and the possible range of velocities, it has been very difficult if not impossible to design a system where both the rear turbine and front compressor are functioning optimally when rotating at identical speed, and thus the potential maximum efficiency is compromised. One design, by McCune as described in, e.g., U.S. Pat. No. 9,752,511 (“McCune”), is to modify the straight shaft with a gearing system to permit the turbine and compressor to operate at different rotational speeds while still directly driven. The design is reported to have improved efficiency by as much as 15%. However, this design is still limited in that increasing and decreasing thrust still requires the shaft driven compressor and turbine to spin up or spin down in response to increased or decreased thrust from the combustion chamber and is subject to significant inertia. It is also somewhat constrained by the air-fuel ratio entering the combustion chamber in that as fuel is increased, there is a period where the fuel mixture is rich until the compressor spins up and additional air flows into the combustion chamber. It is therefore possible to flood the engine with fuel and potentially cause the engine to fail or flame out, limiting the rate at which thrust can be increased. McCune is incorporated by reference for all purposes.
In the rotary-winged vehicle system 300 of
In yet another embodiment, there is no turbine connected to a generator and the electrical power is generated by a multiplicity of other sources, including but not limited to the movement of the vehicle itself, a rotor powered by the jet thrust, or a separately fueled power source.

With attention to
The rotary-winged system 400 further comprises an electric motor 461 and an electrical generator 450, both coaxially mounted about a central spindle shaft 421. The electrical generator 450 generates electricity by way of the rotation of the shaft 421, and supplies electricity to the electric motor 461; which in turn powers the centrifugal compressor 462. The centrifugal compressor 462 provides compressed air to the combustion chamber 435, which in turn expels thrust through exhaust 439. In the embodiment of
The rotary-winged system 400 of
Returning to
The centrifugal compressor 462 is located centrally at a rotor hub area and is driven by electric motor 461. The centrifugal compressor 462 is located coaxially to the centrally located motor 461 and generator 450, the generator 450 itself connected radially to the set of rotor blade 410. Compressed air from the centrifugal compressor 462 is piped down, via fluid pipe 413, to and along one or several of the rotor blades 410 to a combustion chamber 435. The compressed air is received by a fluid pipe contained within a rotor blade 410, the fluid pipe 413 disposed within an interior of the rotor blade 410. The compressed air is mixed with fuel, liquid or gas, which is burned to produce thrust out exhaust pipe 439. The combustion chamber 435 is located at a distal (or radially far) point of the rotor bland 410 (i.e., at the rotor tip 412) and positioned such that the exhaust thrust causes the rotor to rotate about the central shaft 421 and thus generate lift.
The exhaust port 439 directs, with aid of one or more exhaust port vanes 441, the generated thrust out from the rotor blade 410. Generally, the thrust is nominally directed in the same plane as the rotor blades and at right angles to the axis of the rotor blades 410. However, the one or more exhaust port vanes 441 may vector the thrust out of this nominal direction. For example, the thrust may be directed slightly downward for additional vertical thrust of the rotary winged system 400.
In one embodiment, one or more of the exhaust port vanes 441 are configurable by way of a control system 610 (see
The electrical generator 450 is coupled to the electric motor 461. The electric motor 461 rotates the centrifugal compressor 462. The electric motor 461 may be connected to the spindle shaft 421 and/or to the rotor blades 412. The collector-diffuser 463 directs and slows the compressed air from the centrifugal compressor 462 to the inside of each of the rotor blades 410.
In one embodiment, a portion of the compressed air generated by the centrifugal compressor 462 may be siphoned off to perfuse ultra-low resistance air bearings or provide cooling to the hub based electric motor 400. Furthermore, in one embodiment, the rotation of the rotor blades 410, as attached to the motor 463 and/or generator 450, may be used to generate electrical power to variously charge storage batteries or to power attached devices. Alternatively, or additionally, the power from the storage batteries may be used to drive the hub-based motor to rotate the rotor blades and to create lift, in addition to or instead of the gas-powered jet engine components.
Each of the rotary-winged vehicle system 400 and 500 may create lift using electric power for a certain period of time, then hydrocarbon power (e.g. gasoline, diesel, propane) to create lift for powered flight for another period of time. Also, the embodiment may also recharge storage batteries or power electrical instruments or devices (e.g. pumps, floodlights, winches). It should be noted that each of the rotary-winged vehicle system 400 and 500 would require some means for counter-torque given the torque generated by, e.g., the power generating system 450. The counter-torque may be provided by any of several techniques, to include a conventional tail rotor, a rotor blade system mounted above or below that depicted in
It should be noted that in some embodiments of the disclosed rotary-winged vehicle systems, the input elements to an engine are physically separate from the exhaust/thrust elements, enabling a larger design space for both engine design and rotary-winged vehicle system design. This is because conventional rotary-winged vehicle systems comprise engines in which the engine input elements (e.g. the input nozzle and air intake sections are positioned in a front cylindrical portion of an essentially continuous cylindrically-shaped engine, with the exhaust/thrust portion at the rear of the cylinder.
In one embodiment, an auxiliary engine, such as a traditional Auxiliary Power Unit (APU) of conventional commercial airliners, is used to power a compressor of an engine (rather than by a turbine shaft engaged by a turbine).
For example, the control system 610 may interact with and control an electric power source to selectively power a rotary-winged system for a selected period of time, then switch to another power source, e.g. burning of a traditional hydrocarbon. The control system 610 may also control recharging of storage batteries or power electrical instruments or devices.
As further examples, the control system 610 may interact with and control engine parameters, such as combustion chamber temperature, pressure, etc. The control system 610 may also control the amount or degree of exposure or size of the voids 216 of
Also, the control system 610 may be configured to operate the rotary-winged system embodiments fully autonomously, i.e. without a human aboard the system.
In some embodiments, the rotary-winged vehicle may be configured to hover with need of forward speed, a capability particularly beneficial for safety during emergency flight conditions.
The above embodiments may, in combination or separately, may utilize computer software and/or computer hardware (to include, for example, computer-readable mediums) for any of several functions such as automated control and state estimation, and furthermore may utilize one or more GUIs for human interaction with modules or elements or components.
