不同海拔高度下的火炮发射极限速度研究

Research on Speed Limit of Gun Launching at Different Attitude

由经典内弹道理论可知,火炮的发射弹丸初速是存在极限的。根据火炮发射弹丸运动模型,推导了理想情况下的火炮弹丸极限速度公式,分析了不同海拔高度环境大气下的弹丸发射极限速度,研究了对火炮初速的影响程度,定量得到了海拔高度、压力比等参数对弹丸极限速度的影响规律,并得出了海拔环境对火炮初速是存在影响的。该问题的解决有助于为相关应用提供参考。

mAccording to interior ballistic theory, muzzle velocity of a gun has a limit. Based on projectile motion model, formula of speed limit under ideal condition was derived, calculation results of limit speed at different altitude were analyzed, and influential rules of a variety of parameters, such as altitude, pressure ratio etc. on speed limit in plateau environment at different altitude were represented quantitatively. The analysis shows that altitude environment has certain influence on muzzle velocity. These results are helpful for solving relative problems.
