Polar Coordinates Algorithm to Compute Thrust Vector of Apogee Engine

简述了远地点发动机推力矢量测试系统的原理;概述了往次试验数据处理所采用的推力矢量计算方法——"线性组合法",着重分析其缺点;提出了计算准确度更高的极坐标计算方法,并给出了极坐标法计算举例。

The principle of Thrust Vector of Apogee Engine testing system was shortly illustrated.A linear compose method was used to compute thrust vector in previous tests.After analyzing the defaults of the linear compose method,polar coordinates algorithm was proposed and well described.A mode was given to show its computing process.
