The invention relates to the technical field of aviation power systems, and discloses a wide-speed-range long-endurance air-breathing nuclear power propulsion system and an aircraft. The wide-speed-range long-endurance air-breathing type nuclear power propulsion system solves the problem that a pure nuclear power propulsion system is difficult to realize high-Mach-number flight due to the limitation of the temperature of the wall surface of a reactor core of a reactor. The system comprises an air inlet channel, a precooler, an air compressor, a nuclear reactor, a first turbine, a combustion chamber, a spraying pipe, a fuel storage tank, a first valve, a second valve, a fuel pump, a flow divider, a second turbine and a mixer. Liquid hydrogen is introduced to precool incoming flow air, the working condition of the gas compressor is improved, the heat exchange temperature difference between the wall surface of the reactor core and the air is increased, the specific impulse and thrust-weight ratio of the system are further improved, and the flight envelope is expanded.
本发明涉及航空动力系统技术领域,公开了一种宽速域长航时吸气式核动力推进系统及飞行器。该宽速域长航时吸气式核动力推进系统解决了纯核动力推进系统由于反应堆的堆芯壁面温度限制而难以实现高马赫数飞行的问题。系统包括进气道、预冷器、压气机、核反应堆、第一涡轮、燃烧室、喷管、燃料储箱、第一阀门、第二阀门、燃料泵、分流器、第二涡轮和混合器。本发明通过引入液氢对来流空气预冷,改善压气机工作条件,增大堆芯壁面与空气的换热温差,进而提高系统的比冲和推重比,拓展飞行包线。
