Abstract: 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.
