The invention relates to the technical field of aviation power systems, and discloses a nuclear power aviation electric propulsion system for a long-endurance aircraft and the aviation aircraft. The nuclear power aviation electric propulsion system solves the problems that a traditional fossil fuel and energy storage type aero-engine is poor in cruising ability, and a nuclear energy aero-engine is too heavy. The system comprises a reactor system, an energy conversion system, a storage battery, a power management unit, a motor and an electric propeller, the reactor system comprises a pressure vessel, a reactor and a control rod, and the energy conversion system comprises a turbine, a rotating shaft, a generator, a gas compressor, a cooler and a heat regenerator. The advantages of high power density of the storage battery and high energy density of the reactor combined closed Brayton cycle power generation device are comprehensively utilized, so that the aircraft has longer endurance time, and meanwhile, a power system is not too heavy.

    本发明涉及航空动力系统技术领域,公开了一种面向长航时飞行器的核动力航空电推进系统及航空飞行器。该核动力航空电推进系统解决了传统化石燃料及蓄能式航空发动机续航能力差,以及核能航空发动机重量过大的问题。系统包括反应堆系统、能量转换系统、蓄电池、电力管理单元、电动机和电动螺旋桨,其中反应堆系统包括压力容器、反应堆和控制棒,能量转换系统包括涡轮、转轴、发电机、压气机、冷却器和回热器。本发明综合利用了蓄电池高功率密度和反应堆结合闭式布雷顿循环发电装置高能量密度的优势,使得飞行器拥有更长的续航时间,同时动力系统不至于过重。
