Description
Technical field
It is more particularly to a kind of based on the lifting of liquid fuel mixing energetic material powder the invention belongs to technical field of engines
The punching engine of thrust.
Background technology
Punching engine be it is a kind of complete pressurized combustion using flowing the deceleration pressurization of high-speed air, so as to carry out
The jet engine of work.Punching engine is not required to carry oxidant, without rotatable parts such as compressor and turbines, with energy
Increase the potential advantages of aircraft load-carrying ability and cruising range.Punching engine is usual by air intake duct, combustion chamber and jet pipe, this
Three critical piece compositions.Head-on air is flowed during flight deceleration is compressed by air intake duct, the air after supercharging enters combustion
Burning room mixes with fuel carries out isobaric combustion, and the high-temperature fuel gas produced after burning are expanded after accelerating in jet pipe and spray, and generation is pushed away
Power.The distinctive performance advantage of punching engine, is more suitable for the requirement of aircraft high speed remote voyage.In high-speed flight, punching press
The thrust ratio turbojet that engine is produced is big, and economy is better than rocket engine.And current punching engine is suitable
It is 3 to 4 or so generally in flight Mach number with being limited in scope.The shortcoming that influence punching engine develops to flying speed higher
It is not enough its thrust.Mainly by both sides reason：One be engine suction process kinetic energy rejection it is big；Two is in engine
The combustion gas dissociation that high temperature is caused.In order to realize air suction type hypersonic flight, its thrust need to be greatly increased, and could break through its application
Barrier.
