该文采用特征线法、正激波理论和牛顿碰撞理论相结合的一种计算方法,估算了脱壳穿甲弹弹托前腔压力,并将估算值用于确定风洞测压试验压力传感器量程,满足测压试验精度的要求.
In this paper, a method combining the characteristic line method, forward shock theory and Newton’s collision theory is used to estimate the pressure in the front cavity of the shell armor-piercing projectile shells, and the estimated value is used to determine the range of the pressure sensor in the wind tunnel pressure- Meet the requirements of pressure test accuracy.
