本文采用试验的均匀设计方法，结合对气动力矩的理论估算，利用计算机仿真，研究了姿态运动对落舱微重力水平的影响．结果表明，在落舱下落的前60s内，要想保持优于10(－3)g数量级的微重力水平，以满足一般科学实验的要求，则必须安装姿态控制系统．
In this paper, the uniform design of the test method, combined with the theoretical estimates of aerodynamic torque, the use of computer simulation, study the impact of attitude movement on the gravity level of falling capsule. The results show that attitude control systems must be installed to maintain microgravity above the order of 10 (-3) g in the first 60 s of falling to meet the needs of general scientific experimentation.
