Abstract

The present invention relates to a recoil rotor engine which mainly comprises a wheel disk, wherein a combustion chamber is arranged in the wheel disk, and a center at one end of the wheel disk is provided with a fuel pipe which is communicated with the combustion chamber; the front end of the fuel pipe is a spray nozzle. The center at the other end of the wheel disk is provided with a coupling shaft. One end of the wheel disk, which is near the fuel pipe, is symmetrically provided with air inlet channels which are communicated with the combustion chamber in a circumferential direction, wherein the front end of each air inlet channel is a ram air inlet channel, and the back end is a curved pressure diffusion pipe. One end of the wheel disk, which is near the coupling shaft, is symmetrically provided with curved De Laval nozzles which are communicated with the combustion chamber in the circumferential direction. The present invention is designed by the working principle of ram compression air inlet and inverse jet driving, and uses the wheel disc structure which combines compression, combustion and air jet, so that the engine can obtain high efficiency and work capacity besides greatly simplifying structure and reducing cost, and can be applied to various fields of power machinery, gas power generation, etc.

Description

The Recoil rotor motor

Technical field

The present invention relates to heat engine, especially a kind of do not have Recoil rotor motor piston and blade, by the rotary cylinder continuous doing work.

Background technique

At present, internal-combustion engine commonly used mainly contains two big classes: internal-combustion piston engine and gas turbine, known internal-combustion piston engine mainly is made up of cylinder, piston, intake and exhaust mechanism and power-converting output mechanism, the piston internal-combustion engine efficiency is higher, but complex structure, life-span is lower, and dimensional weight is bigger, and power is lower; Known gas turbine mainly is made up of gas compressor, firing chamber, turbine, and gas turbine can continuous doing work, and power is bigger, but efficient is on the low side, and the impeller design processed complex is to the material requirements height, the turbine blade heat load is big, and this has just restricted the further raising of engine performance.In fact, through constantly development, no matter be internal-combustion piston engine or gas turbine, therefore its development potentiality limit that become presses for by using new approaches, new methods such as new principle, new structure and promotes its further development.

Summary of the invention

Purpose of the present invention just provide a kind of simple in structure, dimensional weight is little, structure good heat resistance, thermal efficiency height, can be by the big internal combustion type Recoil rotor motor of cylinder continuous doing work, acting ability of high speed rotating.

Recoil rotor motor of the present invention is by using punching press compress inlet air and the working principle design of regurgitating driving, compression is melted in employing, burning, jet is the wheeling disk structure of one, engine body structure is a wheel disc, the firing chamber is built in the wheel disc, fuel pipe is established in wheel disc one end center, fuel pipe communicates with the firing chamber, the fuel pipe front end is a nozzle, the other end center of wheel disc is a joining shaft, wheel disc along the circumferential direction is arranged with the intake duct that communicates with the firing chamber by fuel pipe one end, the intake duct front end is a ram air duct, the rear end is crooked diffuser pipe, wheel disc along the circumferential direction is arranged with the crooked laval nozzle that communicates with the firing chamber by joining shaft one end, and the entry end or the outlet end of intake duct are provided with closed loop, and closed loop links to each other with the startup operating handle.Wheel disc middle part circumference is provided with annular partition plate, mixes to prevent inlet and outlet, and to the ground dynamic power machine, separating device also can be designed to heat exchanger.Wheel disc is an overall structure, for easy to process, also can adopt the branch body structure, links to each other by bolt.Joining shaft and wheel disc can be connected as a single entity, and also can adopt the branch body structure.Wheel disc internal combustion locular wall and laval nozzle wall high-temperature area adopt stupalith.

Recoil rotor engine operation principle of the present invention is: engine body structure is the wheel disc of a high speed rotating, during startup, behind intake duct filling oxygenant, promote to start operating handle, make closed loop sealing intake duct, spray into fuel oil and igniting, enter the rocket motor working state, rotate by the tangential jet driving wheel disc acceleration of spout.When reaching working speed, oppositely promote operating handle, open intake duct, beginning punching press air inlet.Also can adopt electric motor starting, motor links to each other by clutch with joining shaft, and when adopting electric motor starting, starting operating handle and closed loop can cancel.When the wheel disc high speed rotating; its edge air-flow relative velocity reaches supersonic speed; carry out the punching press compress inlet air by ram air duct place shock wave; pass through crooked diffuser pipe again; make air-flow obtain higher pressure ratio and enter the firing chamber to burn with cyclone mode; fuel (fuel oil; combustion gas or coal dust etc.) spray into by the axle center fuel pipe; also can suck by the negative pressure at the rotatable gas center that is similar to tornado in the cylinder; carry out swirl flow combustion; owing to structural reason, can all adopt stupalith at chamber wall and jet pipe wall, one can allow higher temperature; improve the acting ability, two can be to the rotor thermal insulation protection.High-temperature high-pressure fuel gas after the burning sprays at a relatively high speed from the laval nozzle of bending, provide driving moment to wheel disc, a part offers intake resistance and inside and outside air-flow and the mechanical friction resistance of wheel disc to overcome intake duct, and another part is externally exported acting with the form of shaft work.

Recoil rotor motor beneficial effect of the present invention is: can make motor at a large amount of simplified structures, reduce cost in, obtain higher efficient and acting ability, promote its application in fields such as all kinds of dynamic power machines and fuel gas generations.
