The invention provides a heat insulation and bearing integrated cabin structure suitable for a wide-area aircraft, a cabin body comprises a bearing layer, a heat insulation layer and an anti-erosion ablation layer which are sequentially and fixedly connected through bonding layers from inside to outside, end frames used for connection are arranged at the two ends of the cabin body, the bearing layer is used for bearing mechanical loads, and the heat insulation layer is used for bearing the mechanical loads. The erosion and ablation prevention layer is used for preventing erosion and ablation of high-temperature pneumatic heat flow, and the heat insulation layer is used for preventing heat flow of the erosion and ablation prevention layer from being transmitted into the bearing layer. The wall thickness of the cabin body is small, lightweight design is achieved, and meanwhile a better installation space is provided for internal equipment; the honeycomb bearing structure with the zero Poisson ratio does not generate thermal expansion under the heating condition, the thermal matching performance between the honeycomb bearing structure and a thermal insulation material is excellent, interlayer connection is firm, and safety is high; the heat prevention and insulation bearing integrated structure can bear various external loads at the same time, it is ensured that the aerodynamic shape of the aircraft is not changed, and the shape maintaining purpose is achieved.

    本发明提供了一种适用于宽域飞行器的防隔热承载一体化舱体结构,舱体包括由内至外依次通过粘结层紧固连接的:承载层、隔热层以及防冲刷烧蚀层,所述舱体两端均设置有用于连接的端框,所述承载层用于承受机械载荷,所述防冲刷烧蚀层用于防止高温气动热流的冲刷和烧蚀,所述隔热层用于阻止所述防冲刷烧蚀层的热流传入所述承载层。本发明舱体壁厚小,实现了轻量化设计,同时为内部设备提供更好的安装空间;零泊松比的蜂窝承载结构在受热条件下不会发生热膨胀,与隔热材料之间热匹配性能优良,层间连接牢固,安全性高;防隔热承载一体化结构能同时承受外部的多种载荷,确保飞行器的气动外形不发生改变,达到维形的目的。
