The invention relates to the technical field of aviation power systems, and particularly discloses a nuclear heat-electricity hybrid propulsion system and an aircraft, the propulsion system comprises a reactor system, a nuclear heat exchanger, a pump, an air inlet channel, an air compressor, a turbine, a spray pipe, a motor, an electric power management unit and a storage battery, and the reactor system comprises a pressure vessel, a reactor and a control rod. When the aircraft is in a take-off and climbing state, a nuclear energy-electricity hybrid propulsion mode is adopted, and when the aircraft is in a cruising state, a pure nuclear energy propulsion mode is adopted, so that the problem that an existing pure nuclear energy propulsion scheme is difficult in practical application due to low power density, potential nuclide leakage risk and weak variable working condition capacity is solved; by introducing a high-power-density electric propulsion technical scheme, the power-to-weight ratio of the system is improved, the endurance time of the aircraft is remarkably prolonged, and meanwhile, high safety and certain maneuverability are ensured.

    本发明涉及航空动力系统技术领域,具体公开了一种核热‑电混合推进系统及飞行器,推进系统包括反应堆系统、核热换热器、泵、进气道、压气机、涡轮、喷管、电机、电力管理单元和蓄电池,反应堆系统包括压力容器、反应堆和控制棒。本发明当飞行器处于起飞和爬升状态时,采用核能‑电混合推进模式,当飞行器处于巡航状态时,采用纯核能推进模式,解决了现有纯核能推进方案因功率密度低、潜在核素泄露风险和变工况能力弱导致实际应用困难的问题,通过引入高功率密度的电推进技术方案,提高系统的功重比,显著延长飞行器续航时间,同时确保高安全性和一定的机动能力。
