The study of the reentry capsule shape optimization method based on the solving of the Euler equations

基于优化软件平台,选用合适的优化算法,完成优化设计。应用快速气动分析软件,通过求解Euler方程得到高超声速气动力特性,求解Fay-Riddell公式计算表面热流,通过算例对比验证了该方法的精度和效率。在CTV返回舱基础上验证并初步形成了快速有效的气动布局优化设计的方法,应用该方法完成了类神舟飞船返回舱外形的初步优化设计,为进一步的优化设计研究工作打下基础。

The work in this paper is based on the optimization software, using the exactly optimization technique. The hypersonic aerodynamic performance is calculated by numerically solving the Euler equations and the maximum surface heat flux is calculated by solving the Fay-Riddell equation. To test our method, the CTV is optimized. The Spaceship reentry capsule has been optimized as a particular instance. This research work can be as the groundwork for the reentry capsule optimization.
