弹药无法改装的地炮甲弹射表编拟方法

Design Method of Firing Table of Ground Artillery's HEAT when Cartridge Cannot be Refitted

针对无法精确测量弹丸飞行体质量和引信无法摘火2种情况下的地炮甲弹射表编拟问题,分别提出了取相同弹重等级的弹丸质量中间值作为该组弹丸质量进行试验,以及取较大射角进行阻力系数试验的方法,并结合某型破甲弹射表编拟试验数据进行了误差分析,结果表明:利用该方法编拟射表的精度满足使用要求。

For the problem of making the firing table of ground artillery High Explosive Anti-Tank( HEAT) shell in two situation that it is unable to accurately measure the projectile mass of flight body and fuse fails to be extirpated,a new method is put forward: taking the middle value of projectile mass of the same mass grade as projectile mass of this group for test,and making drag coefficient test in a big elevation. The error analysis is done using test data of firing table of a certain model HEAT shell. Results show that the firing table's precision by this method can meet application need.
