The invention provides an aircraft head cabin for a hypersonic speed environment, and relates to the technical field of aircraft heat insulation, a heat protection assembly is arranged outside the aircraft head cabin, the aircraft head cabin comprises a bearing layer and a heat protection layer, the bearing layer is provided with a bottom plate, and a lattice structure is arranged on the side, away from the head cabin, of the bottom plate and is composed of a plurality of lattice units; first gaps are formed among the dot matrix units; the heat-proof layer is arranged on the side, away from the head cabin body, of the bearing layer, and the first gap is filled with the heat-proof layer; in the preparation process, the heat-proof layer and the bearing layer are prepared together, and the two layers are in gapless connection to form an integrated heat-proof system, so that the maintainability of the heat protection assembly is improved; meanwhile, the lattice structure can reduce the mass while ensuring the strength, and when the heat-proof layer and the bearing layer are integrally prepared, additional connecting structures and supporting parts can be avoided, so that the overall mass of the head cabin is further reduced, the waste of space is reduced, and the performance of the aircraft is improved.
本申请提供一种用于高超声速环境的飞行器头部舱体,涉及飞行器隔热技术领域,外部设有热防护组件,包括:承载层和防热层,承载层具有底板,底板远离头部舱体的一侧设有点阵结构,点阵结构由多个点阵单元构成,点阵单元之间具有第一间隙;防热层设在承载层远离头部舱体的一侧,且防热层填充在第一间隙内;在制备过程中,防热层与承载层制备在一起,两层之间无间隙连接,形成一个一体化的防热体系,提高热防护组件的维护性;同时,点阵结构可以在保证强度的同时减轻质量,将防热层与承载层一体化制备时,可以避免额外的连接结构和支撑部件,进一步减轻头部舱体的整体质量,减少空间的浪费,提高飞行器的性能。
