Description
Technical field
It is more particularly to a kind of to be pushed away based on combustion chamber penetrating energetic material powder lifting the invention belongs to technical field of engines
The punching engine of power.
Background technology
Punching engine is a kind of using pressurized combustion is completed to flow 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 aircraft load-carrying ability and the potential advantages of cruising range.Punching engine generally by air intake duct, combustion chamber and jet pipe, this
Three critical piece compositions.During flight, deceleration is compressed by air intake duct to flow head-on air, the air after supercharging enters combustion
Burn room and progress isobaric combustion is mixed with fuel, the high-temperature fuel gas produced after burning expanded in jet pipe and sprayed after acceleration, 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 higher flying speed
It is that its thrust is not enough.Mainly by both sides reason：One be engine suction process kinetic energy rejection it is big；Two be 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.
