为解决非旋弹、微旋弹配用引信所采用的机电安全系统通用性差、环境适应性不强等缺点,在分析美海军鱼雷引信中所采用的基于微机电压力流量传感器的解除保险方式的基础上,研究了陆军引信安全系统利用弹丸速度与高度信息解除保险方案。对与弹丸速度和高度有一定关系的弹丸外流场压力的测量进行了深入分析,并对弹丸速度测量、高度测量原理做了理论研究。最后设计了弹丸感压孔设置方案,说明了这种引信安全系统理论可行。

To resolve the question of bad universality and bad adaptability of environment of electro-mechanical safety and arming of non-spinning and slight rotary projectile fuze, research was carried out on army projectile fuze arming by velocity and height information after a-nalysis of a MEMS pressure sensor based mode to relieve the safety and arming of torpedo of USA navy. The projectile flow field pressure measurement which having relationship with the projectile velocity and height was researched, and some theoretical study on the projectile velocity measurement and high measurement was done. Finally, the scheme of projectile pressure sensing hole was designed, showing the feasiblility of the safety system.
