摘要
月球着陆探测器发动机推力线测量及标定是发动机装配与调整的关键环节。通过创建精测镜坐标系,实现发动机在对接面坐标系中的推力线平行量与偏斜的转换,得到热试车后标定推力线的方法。通过发动机热试车后数据分析,推力线测量及标定方法满足技术条件要求。
Measurement and calibration of lunar lander engine thrust line is a key link in the pro-cess of engine assembly and adjustment. In this paper, the conversion between thrust line parallel and oblique of the engine in the docking surface coordinate system is achieved by creating coordinate sys- tem of the accurate measurement mirror, and the calibration method of the thrust line is obtained in engine thermal test. The analysis of data got in the engine hot test indicates that the measurement and calibration methods can satisfy the requirement of technical index.
