Abstract

The invention discloses a self-balancing pulse detonation engine which comprises an engine body. The engine body comprises an engine body, an air valve, a hinge, a connecting rod, an ejector rod, a spark plug, a piston, an air inlet pipe, a self-balancing air supplementing pipe and a fulcrum. The machine body comprises a cavity and a combustion chamber, the cavity is arranged on the left side of the machine body, and the combustion chamber is arranged on the right side of the machine body; a baffle is arranged between the cavity and the combustion chamber, an air inlet hole is formed in the baffle, one end of the air valve is arranged in the combustion chamber, and the other end of the air valve penetrates through the air inlet hole to be connected with the hinge. Under the condition that no external mechanism does work, the circulation process of the engine from air inlet to combustion and exhaust is conducted quickly, about 40-50 times of self balance can be achieved within one second, and more than one hundred of stable and effective air inlet, oil supply, high-speed injection and mixing, detonation and exhaust are completed in a reciprocating mode; according to the invention, air intake can be effectively and automatically balanced, and automatic high-frequency pulse deflagration is achieved.

Description

technical field [0001] The invention relates to the technical field of aerospace engines, in particular to a self-balancing pulse detonation engine. Background technique [0002] Compared with the traditional gas engine, the pulse detonation engine has the advantages of high cycle thermal efficiency, low fuel consumption rate, simple structure, light weight, high thrust-to-weight ratio, large specific impulse, and adjustable thrust. Although there are many advantages of pulse detonation engine oil, there are still many technical difficulties that need to be overcome, otherwise it will not be practically applied. The main performance is that the flow process in the engine is very complicated. In the harsh high temperature and high pressure environment, the frequency of detonation combustion must be higher than 100 Hz to generate a large enough specific impulse, and its efficiency may be better than that of a turbojet engine. . It is very difficult to refill and re-explode i...
