关于火箭发动机推力偏心率的分布规律的假设,长期以来没有得到验证.本文根据3号、4号火箭试验的大量测试数据,用数理统计的方法进行统计检验,判明了推力偏心率■在直角坐标系CXY(C为全弹质心)坐标方向上的投影Δx和Δy的分布规律.从而证实了有关分布规律的假设。
The assumptions about the distribution rule of rocket engine thrust eccentricity have not been validated for a long time.Based on a large number of test data of rocket test of No. 3 and No. 4 and statistic test with mathematical statistics, Is the distribution of the projection Δx and Δy in the coordinate direction of CXY (C is full center of mass), confirming the hypothesis about the distribution law.
