Anti-electromagnetic Interference Method ofElectromechanical Penetration Fuze

针对机电侵彻引信解除隔离后受到电磁干扰引起早炸的问题,提出一种机电侵彻引信目标基短路抗电磁干扰方法。该方法设计了一种目标基短路机构,开展了起爆电路参数匹配性计算并改进了软件起爆策略。利用仿真和试验对该方法的有效性进行验证,结果表明,短路机构可适应飞行和着靶环境,发火电容受电磁干扰意外放电后可实现再次起爆,提高了侵彻引信解除隔离后抗干扰能力和作用可靠性。该方法为机电侵彻引信抗电磁干扰提供了一种新的技术途径。

In order to improve the anti-electromagnetic interference(EMI)performance of the electromechanical penetration fuze,a target based short circuit method was proposed to improve the anti-electromagnetic interference performance of the penetration fuze.A target based short circuit mechanism was connected between the initiating circuit and the electric detonator to ensure that any electromagnetic interference would not lead to the accidental action of the fuze in the time window before the fuze was separated from the warhead to touch the target.Simulation and experimental results showed this method could improve the anti-electromagnetic interference performance of the penetration fuze and ensured the reliability of the fuze.
