文章介绍了Ma(马赫数)<6的飞行器典型部位的气动加热与热响应耦合分析及试验验证技术。气动加热计算模块采用的是工程算法,同时将其集成到自主开发的结构有限元三维温度场计算ASTSA软件平台上,实现了气动加热与热响应耦合分析功能。在结构地面热试验方面,成功研发了全方程热流密度PLC控制热模拟试验系统,并利用该系统进行了高速飞行器结构气动加热与热响应耦合地面模拟试验。试验与数值分析的结果对比显示,二者吻合较好,验证了本数值分析方法的正确性。
The article introduces the aerodynamic heating and thermal response coupling analysis and experimental verification of typical aircraft parts with Ma <6. Pneumatic heating calculation module adopts engineering algorithm, and integrates it into ASTSA software platform of finite element three-dimensional temperature field independently developed to realize the function of coupling analysis between pneumatic heating and thermal response. In the aspect of structural ground thermal test, a full-scale heat flux density PLC controlled thermal simulation test system has been successfully developed. The system was used to simulate the ground-based aerodynamic heating and thermal response coupling of high-speed aircraft structures. The comparison between the experimental and numerical results shows that the two agree well with each other, which verifies the correctness of the numerical method.
