The invention provides a propulsion motor with a thermal protection structure and an aviation hybrid power system thereof. The propulsion motor is installed on an engine turbine shaft and located in an engine exhaust nozzle; a shell is arranged on the upper portion of the propulsion motor, an anti-radiation heat insulation structure is installed on the shell, and a heat insulation cavity is formed among the anti-radiation heat insulation structure, the shell and the propulsion motor and used for circulating low-temperature gas to cool the propulsion motor. According to the invention, heat generated by the motor can be taken away, most of radiation influence can be isolated, cooling of the motor is further enhanced by means of air-entraining cooling, the temperature of the motor is effectively reduced, and the safety of the engine is ensured.

    本发明提供了一种具有热防护结构的推进电机及其航空混合动力系统,所述推进电机安装在发动机涡轮轴上,位于发动机尾喷管内;在所述推进电机的上部设置有一壳体,所述壳体上安装有一防辐射隔热结构,所述防辐射隔热结构、所述壳体和所述推进电机之间形成一隔热腔,用于流通低温气体对所述推进电机进行冷却。本发明可以在带走电机自身产热的同时,隔绝绝大部分辐射影响,引气冷却的措施则是进一步加强了对电机的冷却,有效降低了电机的温度,保证发动机的安全性。
