Multi-functional Grenade Key Technologies

Rifle grenade is a super caliber projectile which is shot by the gun and the bullit, it is mainly used to kill personnel target and annihilate all kinds of field fortifications, such as light armored vehicles,blockhouses etc. Combining the research of development pattern of rifle grenade and aiming at the research of single function of rifle grenade, on the basis of especial operation performance of rifle grenade, a new rifle grenade gathering with armor penetration,fragment,incendiary,,extended-range is studied.Due to the application of rocket engine, rifle grenade's flying ballistics become more complicative which leads to many factors affecting the range. On the basis of the theory exterior ballistics of rockets, this paper builts the mathematical model of external ballistics of extended-range rifle grenade, discusses the relations of parameters satisfying the maxi-range requirements and firing distance, finally accomplish a 50% improvement in the range which is one of the characteristics of this paper; in order to increasing efficiency of rifle grenade, by empirical formula and numerical simulates, analyzing the matching problem of shaped charge and incendiary agent, the calculated result is approved by experiment. The configuration of extended-range rifle grenade is effective.
