Description
Technical field
The present invention relates to one kind can loading type multiple-pulse solid propellant rocket, belong to Solid rocket propulsion field.
Background technique
Solid propellant rocket structure is simple, easy to use, and safety is good, high reliablity, no matter in strategy, tactical missile
Above or in space industry, it all played an important role.But compared with liquid-propellant rocket engine, solid propellant rocket
Flexibility is also lacked in terms of controllability, to affect using and developing for it.For this purpose, the states such as the U.S., Japan are from the seventies
Start just to can repeatedly start and provide the multiple-pulse of interval thrust not rocket engine has carried out comprehensive and systematic research admittedly
And exploitation.
Solid propellant rocket can be neatly distributed by the aircraft of dynamical system of multiple-pulse solid propellant rocket
Energy makes the farther distance of aircraft flight；Simultaneously for from closely to remote various ranges, it can also pass through and adjust the pulse spacing
Reach optimum performance.In addition, aircraft can terminal velocity and latter end thruster vector control with higher, can use so smaller
Missile wing and tail vane realize maneuvering flight, strengthen the concealment and penetration ability in flight period.
In order to which above-mentioned advantage is better achieved, the development trend of pulse solid rocket engine is that pulse number is more more
(for example being greater than 5), rather than the domestic dipulse or three pulses mainly studied now.The method of traditional increase pulse number
Be add more pulse units in a combustion chamber, but this certainly will increase the structure size and quality of combustion chamber, while by
In the increase of free volume, it will also result in pulse unit ignition difficulties, it is unreliable to work.In addition, the thrust of each pulse unit
All be it is preset, size is also unmodifiable during the work time.
Summary of the invention
The object of the present invention is to provide one kind can loading type multiple-pulse solid propellant rocket, the device by powder charge storage with
Combustion chamber separates, and no less than 5 subpulses may be implemented, so that pulsed motor energy management, range increase, aircraft end machine
The advantages such as dynamic enhancing are more prominent；Device does not increase the size of combustion chamber, lights a fire relatively reliable yet；Additionally by control filling dress
The number of medicine, can be with the size of flexible modulation thrust.
The purpose of the present invention is what is be achieved through the following technical solutions.
One kind can loading type multiple-pulse solid propellant rocket, comprising: medicine storage device and improves combustion chamber；
The improvement combustion chamber is that chamber cap opens up through-hole before the combustion chamber in multiple-pulse solid propellant rocket, for filling
