Timing control of impulse self balancing latch opening of expansion wave gun

Abstract Aiming at the problem of accurate latch opening control expansion wave gun automatic gun, mathematical model time is established, travel curve projectile and wave, velocity are studied, occurrence close to simulated analyzed; The time-space evolution relationship between local sound velocity, gas simulated; average pressure chamber resultant force two launch modes compared analyzed. After moves for 2.7ms, significantly reduced; dynamic inertial established; changes initial recoil under different times studied. test shows that distance greatly reduced when decreases very weakly, which simulation calculation accurate.
