本文提供了改进的空间Euler方程推进方法和稳定方法,可有效地计算再入机动飞行器的流场,然而,这种数值方法计算再入飞行器的气动特性耗机时多,经费昂贵。 本文发展了一种新的近似计算方法,其计算结果与数值解和试验相比相当吻合,计算机时仅为数值计算的0.2％,对于工程应用,该方法是有数的工具。 This paper provides an improved space Euler equation propulsion method and stabilization method, which can effectively calculate the flow field of reentry maneuvering aircraft. However, this numerical method is more expensive and time consuming to calculate aerodynamic characteristics of reentry vehicle. In this paper, a new approximate calculation method is developed. The calculation results are in good agreement with the numerical solution and the experimental results. The calculation is only 0.2% of the numerical calculation in the computer. This method is a good tool for engineering application.
