摘要
高射弹丸的阻力特性测定较为繁杂费时。以空中炸点声光信号分别测定出弹丸的空炸时间和空炸回声传播时间,根据弹丸质心运动方程组和空炸回声传播时间计算公式,便得到了高射弹丸的阻力特性。这一方法简便易行,实例表明精度也可以满足工程应用要求。以此方法可以判定引信自毁时间射击试验所配用的弹丸弹道是否出现异常而需要剔除。采用简易声光测时系统并对射击条件和气象条件作出限定,可提高测定精度。
It is complicated to measure projectile＇s resistance feature. According to light signal and echo signal of explosion of projectile in air, projectile flight time and echo spreading time can be separately measured. At same time, by exterior ballistic theory about equation group of moving projectile＇,s centroid and by formula of echo spreading time, projectile＇s resistance feature can be got, This way is easy to be realized. By examples,it＇s precision can also satisfy project＇s demand. By this way,if projectile＇s trajectory becomes wrong, which is configured in shooting experiment about fuze＇ self-destroying time,we can judge whether or not to eliminate it. If using simple light and sound measuring system. and limiting shooting condition and weather condition, precision can also be improved.
