为满足未来深空领域月球探测、火星探测及小行星探测项目的综合测试需求,验证复杂航天器返回着陆舱段的回收过程逻辑时序的准确性和可靠性,本文提出了返回式航天器回收功能和性能指标的地面半物理式激励测试系统,实现对整器回收分系统火工品起爆脉冲信号序列的检测和分析。文中通过对舱段模拟飞行试验数据的分析,验证了该测试系统及测试方法的准确性和有效性。
In order to meet the comprehensive testing requirements of the lunar exploration, Mars exploration and asteroid exploration projects in the deep space in the future, the accuracy and reliability of logic timing of the recovery process of the complex spacecraft returning to the landing space are verified. In this paper, the recovery function of the return spacecraft And performance indicators of the ground semi-physical excitation test system to achieve the entire recovery subsystem pyrotechnic product initiation pulse signal sequence detection and analysis. In this paper, through the analysis of flight test data of cabin section, the accuracy and validity of the test system and test method are verified.
