| 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. |
