| 摘 要： | Schamberg的“超热力学自由分子流”粒子——表面作用模型已用于计算凸体的阻力系数。本文进一步给出按此模型计算凸体气动力矩的公式,并推荐反射束半顶角φ_0与入射角θ_1之间的函数表达式。

| Abstract: | The particle-surface interaction model in "hyperthermal free-molecule flow" postulated by Schamberg has been used to calculate drag coefficient of convex bodies.This paper further gives calculation formulas of aerodynamic moment of convex bodies using this model and proposes a functional expression of relationship between the half-angle of beam φ_0 and the angle ofincidence θ_i. |
