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.
