The invention relates to the technical field of satellite-borne component unlocking, and provides a method for unlocking a satellite-borne component by using an elastic heat knife unlocking device, which comprises the following steps: after a satellite is launched into an orbit and when the satellite-borne component needs to be unlocked, electrifying a lead of a heat knife of the elastic heat knife unlocking device so as to heat a knife rod of the heat knife to reach a melting point of a rope; and after the rope is fused, unlocking of the on-satellite component is realized. The elastic hot knife unlocking device used by the invention is relatively low in manufacturing cost and short in production period; the impact during unlocking is small, and the stability of the satellite in the running process is improved; the strength and the reliability are high; and the occupied volume is small, the installation is simple and convenient, and the application value is high.

    本发明涉及星上部件解锁技术领域,提出一种使用弹性热刀解锁装置解锁星上部件的方法,其中在卫星发射进入轨道后,需要解锁星上部件时,通过弹性热刀解锁装置的热刀的引线加电以使得热刀的刀棒升温达到绳索的熔点,绳索熔断后实现星上部件的解锁。本发明使用的弹性热刀解锁装置造价相对低廉并且生产周期短;在解锁时的冲击小,有利于提高卫星运行过程中的稳定性;强度和可靠性高;以及占用体积小,安装简便,具有较高的应用价值。
