Rotation-type pulse detonation engine

Abstract

The invention relates to a rotation-type pulse detonation engine. The cycle operation period of the rotation-type pulse detonation engine can be subdivided into the five processes of air suction, air exhaust, oil injection, ignition, detonation and jet. The rotation-type pulse detonation engine is mainly composed of an output shaft, an air cylinder, a rotor, a sealing pad and a bearing fixing plate. The output shaft and the rotor are assembled together through a spline. The output shaft, the sealing pad and the bearing fixing plate are installed together through bearings. The sealing pad, the bearing fixing plate and the air cylinder are fixed together. The output shaft with the rotor is located inside the air cylinder. Blades on the rotor divide the inside of the air cylinder into a plurality of fan-shaped body spaces evenly. The rotor, the sealing pad and the inner wall of the air cylinder form a closed detonation chamber which is also a fan-shaped body. The wall of the air cylinder is provided with air inlets, oil injection openings and lighting-up openings. The sealing pad is provided with jet openings, exhaust outlets and exhaust outlet adjusting devices. The detonation chamber is arranged in the spiral direction.

Description

technical field [0001] The present invention relates to a new type of conventional fuel engine. Background technique [0002] Since human beings have used the thermal power of conventional fuels, steam engines, two-stroke engines, four-stroke engines, rotary engines, turbojet engines, turbofan engines, and rocket engines have been invented. The pulse detonation engine is still in the research stage and has not yet been successfully developed. . The pulse detonation engine has the advantages of environmental protection, small size, high power, simple structure, easy production, fuel saving, etc. It is a dual-mode engine, namely the rocket engine mode and the air-breathing pulse detonation engine mode, used in the aerospace field . The auxiliary facilities of the traditional pulse detonation engine are complicated, and the current research progress is slow. The whole world has studied it for more than 70 years, but the research has not been successful, and may have entered a...

Problems solved by technology

For example, China invested tens of billions to establish a large aircraft project. The engine cannot be produced by itself. It has to be bought from Europe and the United States. Europe and the United States find various excuses to delay delivery, which hinders the development of China's large aircraft, and its future fate is still unknown; another example is China's advanced fighter jets. , large transport aircraft, and large ships have been repeatedly delayed due to lack of advanced engines

China has also invested a lot of manpower and material resources in research, but it is all imitation and follow-up, with little effect
