| 摘 要： | 姿控发动机真空环境下工作产生的喷流对航天器造成的污染非常严重.根据污染的性质,羽流污染又分为机械污染、热污染、沉积污染和化学污染.用直接模拟的蒙特卡罗(DSMC)法数值求解真空羽流场,在此基础上计算热污染和沉积污染,将对空间飞行器的设计和科学实验有参考价值.

| Abstract: | The ejective flow produced by attitude control engine creates serious contamination to spacecraft, which can be classified, according to property, into mechanical,thermal, depository and chemical contamination. The calculation of this contamination is of referential value to the design and experiment of spacecraft on the basis of the numerical solution to vacuum plume flow field with DSMC method. |
