- rarefact ion wave gun 膨胀波火炮
- The newly developed rarefaction wave gun(RAVEN) can achieve low recoil momentum without decreasing the muzzle velocity of the projectile by means of delayed venting the breech. 膨胀波枪炮利用延时打开膛尾的方法实现了在不降低弹丸初速的前提下大幅度减小枪炮后坐的目的。
- Gun recoil force reduction technology mainly include out-of-battery, superlong and tandem superlong recoil,2D recoil, muzzle braking, rarefaction wave gun and electromagnetic rheologic fluid etc. 膨胀波火炮红外目标特征太明显,要求能精确控制火炮相关机构,需系统、全面地研究探索内弹道技术、火炮自动机技术等相关技术。
