随着对飞行器更高速度、远距离的发展要求,所遇到的气动加热问题越发突出。文中基于ANSYS软件,以典型旋成体球头钝锥为计算模型进行飞行状态下的热环境计算,建立了完整的数值求解方法。验证了ANSYS软件可以有效求解气动热问题,并对流场、温度场、结构场特性进行了数值分析研究,为防热设计和优化提供了可靠的参考依据和分析手段。

With the development requirement of the aircraft at higher speed and longer distance, the aerodynamic heating problem becomes more and more serious. Based on ANSYS software, the ball head blunt cone in a typical body is taken as the calculation model for calculation of thermal environment in flight conditions. A complete numerical solution method is established. It is verified that ANSYS software can effectively solve the problem of aerodynamics. And the convection field, the temperature field, and the structural field characteristics have been studied, providing a reliable reference and analysis to the thermal design and optimization.
