| Abstract: | 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. |
