摘　　要：高速飞行器对结构效率的苛刻要求使得热防护系统不断向轻质化、集成化方向发展,新型的力热耦合一体化热防护系统(ITPS)极具发展潜力。本文介绍了ITPS的结构特征,并对ITPS在机翼结构中的热响应进行了分析,包括优化分析、瞬态温度场分析以及考虑空气压力的热应力分析。结果表明,在机翼外表面施加ITPS结构是可行的。High speed aircraft has rigorous requirement of structural efficiency,which makes the thermal protection system constantly tend to the development direction of lightweight and integration. New thermo-mechanical coupling model of integrated thermal protection system（ IPTS） has great development potentialities. The structural characteristics of IPTS are introduced in the paper,and the thermal response of IPTS in wing structure is analyzed,including optimization analysis,transient temperature field analysis and thermal stress analysis of air pressure. The results show that ITPS is applied in the outer wing surface is feasible.
