The invention relates to an active and semi-active coupling thermal protection structure, and belongs to the technical field of thermal protection of high-speed aircrafts. The active/semi-active coupling thermal protection structure comprises a dredging structure shell, a dredging structure capillary core, a dredging working medium, an active cooling pipeline, an active cooling working medium, an active cooling pipeline inlet and an active cooling pipeline outlet. A semi-active thermal protection structure represented by a dredging thermal protection structure is adopted to quickly transmit heat to the tail end of a front edge structure or a large-area area from local hot spot parts such as a sharp front edge and an overflow port, and then an active cooling structure represented by a fuel active cooling structure is adopted in a large-space area to achieve effective energy dissipation. A composite heat-proof structure combining an active cooling structure and a semi-active thermal protection structure is formed, and by means of huge heat sink provided by the active thermal protection structure, long-time strong heat dissipation capacity is provided for a dredging thermal protection structure, and the heat-proof performance is further improved.

    本发明涉及一种主动半主动耦合热防护结构,属于高速飞行器热防护技术领域。所述一种主动/半主动耦合热防护结构,包括疏导结构壳体、疏导结构毛细芯、疏导工质、主动冷却管道、主动冷却工质、主动冷却管道进口、主动冷却管道出口。采用以疏导式热防护结构为代表的半主动式热防护结构将热量从尖前缘、溢流口等局部“热点”部位快速传输至前缘结构尾端或大面积区域,然后在大空间区域采用以燃油主动冷却结构为代表的主动式冷却结构实现能量有效耗散,形成主动冷却结构和半主动式热防护结构相结合的复合防热结构,依托主动式热防护结构提供的巨大热沉,为疏导式热防护结构提供长时间的强热耗散能力,进一步提升防热性能。
