本文针对可重复使用热结构，计算研究了类前缘外形热结构防热层瞬态热响应问题，探索分析了前缘防热层的热响应特征．在计算中成功地实现了任意坐标变换下代数网格生成，并求解了任意坐标下的热传导方程，为进一步开展外流场／结构热响应全耦合一体化计算研究打下了基础． Aiming at the reusable thermal structure, this paper studies the transient thermal response of heat-insulating layer of thermal front-like structure, and explores the thermal response characteristics of the front thermal layer. The generation of algebraic grid with arbitrary coordinate transformation and the heat conduction equation under arbitrary coordinates are successfully implemented in the calculation, which lays the foundation for the further study on the fully coupled and integrated calculation of thermal field / structure thermal response.
