基于薄/厚识别开关的引信自适应延期方法

Fuze Adaptive Delay Time Control Based on Target Thickness Recognition Switch

针对引信采用固定延期起爆方式的攻坚弹的炸点难以适应不同厚薄目标的问题,提出了基于薄厚目标识别开关的攻坚引信自适应延期方法,该方法利用薄厚目标识别开关对薄厚目标的反应不同给出两种不同的信号,延期起爆时间调整电路据此给出两种不同延期时间。仿真表明:基于薄厚目标识别开关的攻坚引信自适应延期方法对厚度200 mm以下,400 mm以上的混凝土目标能够进行自适应起爆控制。

The fuze of fixed time delay detonation of hard structure ammunition can not adapt to different thickness of the targets.To solve the problem,an self-adaptive delay time control method based on target thickness recognition switch was presented for hard structure ammunition fuze.Two signals of different thickness of the targets could be given by the target thickness recognition switch and the corresponding delay time was put out by delay control circuit.Simulation results showed that the designed device could distinguish the thickness of concrete targets at 200 mm less and 400 mm over,and adaptively control the time delay detonation point effectively.
