摘要： Schamberg的“超热自由分子流”粒子-表面作用模型比较真实地反映了高空大气分子与空间飞行器材料之间的相互作用,它可以用来计算卫星的阻力系数。本文简要叙述该模型的基本思想,介绍几种常见简单几何形体卫星的阻力系数计算公式,并给出计算曲线。

Abstract: Since Schemberg's Particle-surface interaction mode in "hyperthermal free molecula flow" represents the inter-action of high atmosphere molecules with the wall material of spacecraft more really, it can be used to calculate the drag coefficients of satellites. In this paper the basic principles of the mode are presented, the calculation formulae of drag coefficients for the satellite with simple geometric shapes are listed and the computing results are given.
