时间冗余电子计转数引信设计

电子计转数引信由于不需要测弹丸的炮口初速，减少了整个引信装定系统的复杂程度，降低了制造成本。进一步分析、试验发现，利用地磁传感器作用原理的电子计转数引信的发射方向上有一个死区，在这一方向区域内发射炮弹，引信不能正常工作．该文在试验的基础上对死区进行了分析，并提出了解决方案，即时间冗余电子计转数引信。

DESIGN OF TIME REDUNDANCY ELECTRONIC TURNS-COUNTING FUZE

When using the electronic turns counting fuze to control the detonating point accurately, it needn't measure the muzzle velocity of the projectile, so the complication of the fuze setting system and the cost of manufacture of weapon can be reduced. The analysis and experiments indicate that there is an invisible field in the shooting direction of fuze which is based on the principle of terrestrial magnetic sensor, and in that direction, the fuze can't work well. The invisible field is analyzed and the solution using time redundancy electronic turns counting faze is given in this paper.
