Abstract

Some embodiments provide a non-piston rotary engine that utilizes flywheel motion to generate power. In some embodiments, the non-piston rotary engine comprises a pair of flywheels and a plurality of rotor assemblies for generating mechanical energy. In some embodiments, each rotor assembly comprises a multi-vane compressor that rotates within a vane compressor housing. In some embodiments, each rotor assembly comprises a rotating combustion disk in a combustion housing. In some embodiments, the combustion housing comprises a plurality of combustion disk chambers for igniting the combustible gas and expelling exhaust fumes created after combustion, wherein combustible gas forced into each combustion disk chamber is combusted, causing the rotor to move in a direction to release exhaust from the combustion.

Claims (32)

1. A non-piston rotary engine comprising:

a first flywheel and a second flywheel;

a plurality of motors, where each motor of the plurality of motors comprising:

a rotating combustion disk including at least two recesses symmetrically disposed about the circumference of the rotating combustion disk;

a housing surrounding the rotating combustion disk to define at least one combustion chamber,

the housing further including at least one combustion port and at least one exhaust port, wherein combustible gas forced through the at least one combustion port into the at least one combustion chamber is combusted, causing the rotating combustion disk to rotate in a direction to release exhaust from the combustion through the at least one exhaust port; and

a gear connected to the rotating combustion disk;

wherein the gear of each of the plurality of motors engages both the first flywheel and the second flywheel such that movement of the rotating combustion disk of each of the plurality of motors causes the respective gear to rotate the first flywheel in an opposite direction from the second flywheel in order to balance power between the first flywheel and the second flywheel.

2. The non-piston rotary engine of claim 1 , wherein the gear of each one of the plurality of motors is a bevel gear comprising a gear rim.

3. The non-piston rotary engine of claim 1 , wherein the first flywheel and the second flywheel comprises an upper flywheel and a lower flywheel.

4. The non-piston rotary engine of claim 1 , wherein the housing comprises an upper combustion bracket and a lower combustion bracket.

5. The non-piston rotary engine of claim 4 , wherein the upper combustion bracket and the lower combustion bracket are connected by a pair of bolts.

6. The non-piston rotary engine of claim 4 , wherein the upper combustion bracket and the lower combustion bracket of each of the plurality of motors comprises a combustion channel through which the combustion chamber receives combustible gas and an exhaust channel into which the combustion chamber releases exhaust.

7. The non-piston rotary engine of claim 4 , wherein the combustion channel and the exhaust channel are on opposite sides of the upper combustion bracket and the lower combustion bracket.

8. The non-piston rotary engine of claim 6 , wherein the combustion channel of the upper combustion bracket is on a first side of the upper combustion bracket and the combustion channel of the lower combustion bracket is on a second side of the lower combustion bracket that is the opposite side of the first side of the upper combustion bracket.

9. The non-piston rotary engine of claim 6 , wherein the exhaust channel of the upper combustion bracket is on a second side of the upper combustion bracket and the exhaust channel of the lower combustion bracket is on a first side of the lower combustion bracket that is the opposite side of the second side of the upper combustion bracket.

10. The non-piston rotary engine of claim 1 , wherein the number of the plurality of motors can be increased to increase the amount of power generated by the non-piston rotary engine.

11. A non-piston rotary engine that generates power using a multi-vane compressor, said non-piston rotary engine comprising:

an upper flywheel and a lower flywheel that rotate in opposite directions to balance the power received from a plurality of motor assemblies;

each motor assembly of the plurality of motor assemblies comprising:

(i) the multi-vane compressor comprising a vane compressor housing, a rotating vane compressor disk, and a plurality of adjustable partition vanes for taking in and compressing combustible gas, and

(ii) a combustion housing comprising a rotating combustion disk and a plurality of combustion disk chambers symmetrically disposed about a circumference of the rotating combustion disk for igniting the compressed combustible gas from the multi-vane compressor and expelling exhaust fumes created after combustion, wherein compressed combustible gas forced into the plurality of combustion disk chambers is combusted, causing the rotating combustion disk to rotate in a direction to release exhaust from the combustion disk chamber and generate rotational energy;

wherein each motor assembly further includes a drive shaft that is connected to the rotating combustion disk and a geared rim; and

each of the geared rims is engaged with both the upper flywheel and the lower flywheel, so that the rotational energy is transferred from each of the plurality of motor assemblies to the upper flywheel and the lower flywheel.

12. The non-piston rotary engine of claim 11 , wherein the combustion housing comprises a spark plug chamber for igniting the compressed combustible gas and a set of exhaust ports for expelling the exhaust fumes.

13. The non-piston rotary engine of claim 12 , wherein the set of exhaust ports comprises an initial exhaust port adjacent to the spark plug chamber and final exhaust port in a sealed volume chamber opposite the spark plug chamber.

14. The non-piston rotary engine of claim 12 , wherein the rotating combustion disk in the combustion housing rotates the combustible gas to the spark plug chamber for combustion and for rotating the combusted gas to the set of exhaust ports.

15. The non-piston rotary engine of claim 11 , wherein the vane compressor housing and the combustion housing are separated by a middle plate.

16. The non-piston rotary engine of claim 15 , wherein the middle plate comprises a curved slot configured to allow the compressed combustable gas from the vane compressor housing to move into the combustion housing.

17. The non-piston rotary engine of claim 11 , wherein the vane compressor housing comprises a plurality of perforations along a perforated wall that allows gas to be sucked into an expanding volume created as the rotating vane compressor disk rotates.

18. The non-piston rotary engine of claim 17 , wherein the adjustable partition vanes adjust when the vane compressor disk rotates.

19. The non-piston rotary engine of claim 18 , wherein the adjustable partition vanes maintain contact with an inner surface of the vane compressor housing to seal off the volume of the compressed combustable gas as the vane compressor disk rotates.
