The invention belongs to the technical field of thermal protection of high-speed aircrafts, and particularly relates to a thermal protection and heat-work conversion system of a high-speed aircraft. Comprising a thermal protection layer, a turbine generator and a spray pipe, the thermal protection layer comprises a cooling working medium storage layer and a catalytic decomposition reaction heat absorption layer which are arranged inside and outside, the cooling working medium storage layer is connected with the inlet end of the catalytic decomposition heat absorption layer, and the outlet end of the catalytic decomposition heat absorption layer is connected with the turbine generator and the spray pipe; a cooling working medium exchanges heat with the aircraft, is subjected to an endothermic decomposition reaction, then enters the catalytic decomposition heat absorption layer and is subjected to an endothermic chemical reaction in the catalytic decomposition heat absorption layer, and generated high-temperature and high-pressure gas enters the turbine generator and the spray pipe for power generation and acting respectively, so that conversion of heat and work is realized. The weight of the thermal protection layer is gradually reduced, meanwhile, gas generated through decomposition is used for other purposes, and multi-stage utilization of pneumatic waste heat and a cooling working medium is achieved.
