摘　　要：针对现有的理论解方法尚不适用于复杂构型飞行器气动力求解的问题,从稀薄气体分子的动力学模型出发,制作等效平面以分析各部分来流的宏观特性,并将入射流和反射流作用分开进行考虑,从而计算出几种典型情况下的气动阻力值。后续验证表明,在分子-壁面间多次碰撞不显著时,此方法能够获得较准确的气动力结果。所提出的气动力计算方法对低轨道飞行器的气动力计算及气动构型优化等工作均具有一定的参考价值。Aiming at the problem that the existing theoretical solution is not yet suitable for the aerodynamic solution of the complex configuration aircraft, starting from the dynamic model of thin gas molecules, the equivalent plane is made to analyze the macroscopic characteristics of the incoming flow of each part, and the incident jet and the reflected flow are considered separately, so as to calculate the aerodynamic resistance values under several typical cases. Subsequent verification shows that this method can obtain more accurate aerodynamic values when multiple collisions between molecules and walls are not significant. The aerodynamic calculation method proposed in this article has a certain reference value for the aerodynamic calculation and aerodynamic configuration optimization of the low-orbit aircraft.
