| 摘 要： | 文章首先对着陆缓冲阶段、反推发动机工作期间物伞系统的运动方程进行推演,得到反推发动机点火控制高度的显式表达;然后据此显式表达,利用计算机模拟法、借助MATLAB统计工具箱对点火控制高度受各项显式因素的影响进行偏差分析,用均方根方法考虑进非显式因素造成的偏差。

| Abstract: | The vehicle - parachute system motion equations during the work action of thrust of the retrorocket are deduced and the expression of initial ignition altitude is found first. Then, applying computer - based simulation method and MATLAB statistics toolbox to analyze random deviation of initial ignition altitude affected by obvious factors. Effects by latent factors are calculated by root - mean - square method. |
