The invention relates to the technical field of rockets, in particular to a one-rocket multi-satellite satellite-rocket separation device which comprises an adapter and a plurality of satellites, the satellites are sequentially stacked on the adapter in the axis direction of the rocket, and multiple sets of elastic pin shaft structures are arranged between the adjacent satellites. An explosion unlocking structure is arranged between the satellite farthest from the adapter and the adapter; when the explosion unlocking structure is in a locking state, the explosion unlocking structure is used for fixing all satellites on the adapter; after the explosion unlocking structure is unlocked, part of the elastic pin shaft structure generates elastic force for driving the satellites to be separated, and the satellites are ejected and separated one by one in the axis direction of the rocket. According to the one-rocket multi-satellite satellite-rocket separation device, the adapter design difficulty and the satellite-rocket butt joint assembly difficulty are reduced, simultaneous unlocking of multiple satellites can be achieved only through one explosion unlocking structure, the structure is simple, and the system reliability is high.

    本申请涉及火箭技术领域,尤其是涉及一种一箭多星星箭分离装置,包括适配器和多个卫星,多个卫星沿火箭轴线方向依次叠装于适配器上,相邻卫星之间设置有多组弹性销轴结构,距离适配器最远的卫星和适配器之间设置有爆炸解锁结构;爆炸解锁结构处于锁紧状态时,爆炸解锁结构用于将所有卫星固定于适配器上;爆炸解锁结构处于解锁后,弹性销轴结构中的部分结构产生驱使卫星分离的弹力,且多个卫星沿火箭轴线方向逐个弹射分离。本申请的一箭多星星箭分离装置,降低了适配器设计难度及星箭对接装配难度,且只需要一组爆炸解锁结构就可以实现多个卫星的同时解锁,结构简单,系统可靠性高。
