摘要
枪炮发射时,枪炮口常常产生大量的炮口烟焰,电磁发射过程中还会产生大量的等离子体团,所以普通的弹丸测速方法不能直接在后效区内进行初速测量。为了有效克服枪炮口的强烈火焰环境,准确捕捉弹丸过靶信号,提出了使用X射线光幕靶在后效区内测弹丸飞离炮口瞬时速度的系统方案,阐述测速系统的结构图,并且给出测速系统各个模块的设计原理和功能,通过室内靶道实验,X射线可以有效的穿透炮口烟焰,捕捉弹丸过靶信号,验证实验系统具有可行性。
The muzzleoften produce a lot of smoke and flame with guns firing, the electromagnetic emission process will produce a large number of plasmoid,ordinary method of muzzle velocity can＇tmeasured directly in aftereffect period. In order to overcome the strong flame environment in the Muzzle, accurately capture the shot off target signa, This paper presents a systematic scheme for measuring the instantaneous velocity of projectile muzzle flying away from the aftereffect period using X-ray light screen target, and gives the designprinciple and function of each module,Through indoor ballistic range experiment, X ray can penetrate the muzzle smoke and flameand capture the trigger signal effectively,verify the feasibility of the system.
