卫星推力器布局方式对高空羽流撞击效应的影响研究

Studying of High-altitude Plume Impingement Effects for Various Satellite Thruster Layout Scheme

通过对高空羽流流场及其撞击效应进行一体化DSMC仿真,得到了三维羽流场中物理量的分布以及羽流撞击干扰物产生的撞击力、力矩、热流量和质量流量。通过改变推力器与干扰物的相对位置研究了推力器布局方式对羽流撞击效应的影响。

With overall DSMC simulation of high-altitude plume flow and impingement effect, both 3-D plume flowfield structure and such impingement effects as force, moment, heat flux and mass flux are obtained. By varying the relative position of thruster and impediment, influence of thruster layout scheme on plume impingement results are studied.
