| 摘 要： | 为研究水下枪械弹丸出枪口的运动速度变化规律,提出了一种膛口速度测试的新方法:在距枪口3 m内,采用一对标准线圈靶,在多个位置点对弹丸进行多次重复测量,并以各位置点的平均速度进行拟合,再反推到枪口,得到枪口速度及弹丸在距枪口3 m内的速度变化规律.该方法避免了常规多个线圈靶同时测量时由于各线圈靶的动态特性不一致而造成的测...

| Abstract: | In order to research the variation regularity of muzzle velocity of the underwater gun bullets,a new measurement method was put forward.A pair of standard coil targets were used to repeatedly measure velocity of bullets at different position within the range of 3 m from muzzle,and the average velocity of different position is used to fit curve.The muzzle velocity and the moving regularity of underwater bullets within the range of 3 m from muzzle were obtained.The dynamic characteristics inconsistency of eve... |
