摘要
现行小口径高炮射表试验,采用多射角射击全弹道符合的方法,试验耗弹量大,周期长,符合计算数据处理量大而繁琐。小口径高炮射弹飞行时间短,有效射距离处于弹道初始段,弹道平直。试验结果和理论均证明,不同射角的阻力系数及符合系数在有效射距离段均无显著性差异。因此,可进行一个射角的射击试验获取弹丸自身阻力系数及符合系数,这样既可减少试验消耗,缩短试验周期,又可减少数据处理量。实践证明,应用一个射角与应用多个射角的射击试验编拟的射表是一致的。
This paper points out the problems of the whole ballistic fitting method based on multiple angles firing in the current small caliber antiaircraft gun firing table test,such as great projectile consumption,long test cycle,and plenty of tedious data processing in the fitting calculation.The small caliber antiaircraft gun projectile has many characteristics such as short flight time,effective shooting distance being in its initial stage,and flattened trajectory.And the test result and trajectory theory show that there are no distinguished differences either between drag coefficients or between fitting coefficients under different firing angles in the effective firing distance range of the small caliber antiaircraft gun.So,the drag coefficients and fitting coefficients can be obtained through the test of one angle firing,which can decrease ammunition consumption,shorten the period of test and enhance the test data processing efficiency.The consistency of the firing tables based on the tests of one angle firing and multiple angles firing is shown by practices.
