The invention provides an ablation-resistant anti-scouring multi-material interlayer heat-proof structure which comprises a buffer layer, a heat insulation composite material and a heat-proof composite material which are sequentially arranged on the surface of a cabin body outwards, and further comprises a fixing device, the cabin body extends outwards from the surface of the cabin body to form a boss, and the fixing device is matched with the boss to fix the heat-proof composite material. The heat-proof composite material and the heat-insulating composite material are reliably connected to the outer surface of the cabin body through a mechanical structure, so that the scouring resistance and ablation resistance of the heat-proof composite material can be effectively exerted, and the performance advantage of low heat conductivity coefficient of the heat-insulating composite material can be fully exerted; the continuity of the aerodynamic shape of the aircraft is guaranteed, the heat insulation performance with the maximum effect is also guaranteed, the aircraft can adapt to various thermal environments and load environments, and the irregular shape requirement of a special-shaped aircraft and the design requirement for heat insulation variable thickness in different thermal environments can be flexibly considered.
本发明提供了一种耐烧蚀抗冲刷的多材料夹层防热结构,包括舱体表面向外依次设置的缓冲层、隔热复材以及防热复材,还包括固定装置,所述舱体自其表面向外延伸有凸台,所述固定装置与所述凸台配合固定所述防热复材。本发明通过机械结构将防热复材和隔热复材可靠连接在舱体外表面,既可以有效发挥防热复材的耐冲刷和耐烧蚀性能,又可以充分发挥隔热复材导热系数低的性能优势;既保证了飞行器气动外形的连续性,也保证了最大效果的隔热性能,可适应多种热环境及载荷环境,能灵活兼顾异型飞行器的不规则外形要求以及为适应不同热环境下防隔热变厚度设计要求。
