摘要
该文以研究脱壳穿甲弹的中间弹道问题为主线,较详细地综述了高速脱壳穿甲弹穿越膛口中间弹道区时所受到的各种扰动因素、以及脱壳穿甲弹飞行姿态的测试技术和观察手段。扰动因素包括脱壳穿甲弹膛内运动时形成的起始偏角、在射流区受到的气动力干扰、脱壳过程的机械干扰及膛口装置的干扰。文末介绍了脱壳穿甲弹弹托的优化设计问题。
This paper mainly aims to research the intermediate ballistic ofsabot discarding projectiles. It summarizes in more detail all kinds of distur-bance when the projectile goes through the muzzle region, and sums up themeasuring techniques and observing methods of flight attitude of the projec-tile,including the initial angle at which the projectile moves in bore,aerody-namic and mechanical disturbances in sabot discard process,and muzzle brake's disturbance. This paper also introduces in the end the optimum design methodof the sabot discarding projectile.
