考虑多场耦合效应的飞行器头罩热防护结构数值分析

Numerical Analysis of Thermal Protection Structure of Aircraft Hood Considering Multi-field Coupling Effect

为了更为高效准确地使用数值分析方法研究多场耦合问题,充分考虑各物理场之间的强弱耦合关系,发展了有限体积法(finite volume method, FVM)和有限元法(finite element method, FEM)相结合的多场耦合分析方法,并应用到飞行器头罩热防护结构的数值分析中,得到了飞行器头罩结构内部的温度和热变形分布,可以为飞行器头罩的热防护设计工作提供参考。

In order to use numerical analysis method more efficiently and accurately to study the multi-field coupling problem and fully consider the strong-weak coupling relationship between various physical fields,a multi-field coupling analysis method combining FVM with FEM is developed and applied to the numerical analysis of the thermal protection structure of the aircraft hood.The temperature and thermal deformation distribution inside the aircraft hood structure are obtained,which can provide reference for the thermal protection design of aircraft hood.
