The invention discloses a high-precision multi-channel synchronous acting initiating explosive device, and belongs to the technical field of separation of an aerospace aircraft and cabin opening of a warhead of a dispenser. The high-precision multi-channel synchronous acting initiating explosive device comprises an electric detonator (3), a detonation box (1) and a multi-path detonation propagation assembly (2) which are connected in sequence. According to the high-precision multi-channel synchronous acting initiating explosive device, by improving an explosion propagation sequence, determining selection parameters of a detonating cord and controlling the explosion propagation length of the explosion propagation assembly, the action synchronism of all output ends of the multi-channel initiating explosive device is greatly improved. According to the high-precision multi-channel synchronous acting initiating explosive device, the time difference range of the synchronous acting of a traditional multi-channel explosion propagation initiating explosive device can be reduced from not more than 1 ms to not more than 1 mus, so that the reliability of separation of the aerospace aircraft and cabin opening of the warhead of the dispenser is effectively improved.

    本发明公开了一种高精度多通道同步作用性火工装置,属于航天航空器分离技术及布撒器战斗部开舱技术领域,包括依次连接的电爆管(3)、起爆盒(1)和多路传爆组件(2);本发明通过对传爆序列的改进、导爆索的选用参数的确定及传爆组件传爆长度的控制,大幅提升多通道火工装置所有输出端作用的同步性;本发明能够将传统多通道传爆火工装置同步作用的时间差值范围由不大于1ms缩减至不大于1μs,从而有效提高航天航空器分离及布撒器战斗部开舱的可靠性。
