本文推导出了确定尾翼脱壳穿甲弹膛外转速下限的公式:并从最有利的射击密集度出发,对该类弹丸膛内、外转速的取值进行了分析计算,同时通过靶场试验及理论分析,对国内外某些已定型的同类产品的转速取值提出了改进的意见. 文中推导出的确定弹丸转速下限的公式(6)亦同样适用于尾翼式火箭和尾翼式炮弹.
In this paper, the formula for determining the lower limit of the rotational speed outside the tail shell is derived. Based on the most favorable shooting density, the values of the inside and outside rotational speed of the projectile are analyzed and calculated. At the same time, through the shooting range test and theoretical analysis , And put forward some suggestions on how to revise the rotating speeds of some similar products at home and abroad.The formula (6) for determining the lower limit of the projectile speed deduced in this paper also applies to the tail-rocket and tail-fired projectile.
