Description
Technical field
Quickly stop working field the invention belongs to solid propellant, and in particular to solid propellant is quick under a kind of condition of high voltage
Blanket and method.
Background technology
Solid engine is widely answered because of its intrinsic advantage in strategy, Tactical Weapon System
With, in order to further increase the mobility and penetration ability of missile weapon system, solid engines not only require to improve controllability,
And require the ability repeatedly started.It realizes solid engines adjustable thrust and repeatedly starts and just need to study flame-out hair
Motivation technology application, and high-performance solid engine depends on its High Voltage operating mode, i.e. combustion chamber operational pressure to carry at present
Height, engine/motor specific impulse performance improve, these just reduce solid propellant Pressure Exponent, thermal stability improves and high-pressure combustion
It can challenge.The flame-out process of decompression belongs to rough burning process, can be to solid by the research burnt to pressure reduction
The combustion mechanism of propellant, especially rough burning mechanism have deeper understanding.
Patent of invention CN201010531622.9 discloses a kind of quick blanket of solid propellant, the device mainly by
Combustion chamber, pressure sensor, photoelectric sensor, priming supply, high-voltage switch gear solenoid valve, gas cylinder and mating computer are adopted
Collecting system etc. at.Punching press is carried out to combustion chamber by booster pump and gas cylinder, it is made to maintain relatively stable initial pressure, igniting
Power supply is connected with high-voltage switch gear solenoid valve, and propellant is lighted while solenoid valve is opened and quickly stops working.By pressure sensor and mating
System records acquisition chamber pressure change curve in real time, and photoelectric sensor judges whether propellant successfully stops working.But the device
There are problems that：Combustion chamber initial pressure is improved by booster pump, high pressure (30Mpa or more from now on cannot be met by being limited in scope
Test)；Cause package unit heavy with gas cylinder booster pump, is required for inflating again before measuring every time and builds pressure, it is complicated for operation,
Increase testing cost.
Existing decompression blanket is mainly used for the quick flame-out of gun propellant, obtains the combustion face of gun propellant combustion transient state
