The invention discloses a dual-mode space nuclear energy propulsion system which comprises a nuclear heat propulsion subsystem with a hydrogen working medium as a propulsion working medium and a nuclear power propulsion subsystem with helium-electric propellant mixed gas as a cooling working medium. A hydrogen working medium and a mixed gas closed loop are heated through a nuclear reactor system, and power propulsion is achieved by spraying a propellant working medium through a convergent-divergent spray pipe and an electric propeller. The advantages of nuclear thermal propulsion and electric propulsion technologies are combined, the novel dual-mode space nuclear energy propulsion system is provided, the thrust range can reach the millyN level to the hundreds of kiloN level, the utilization efficiency of propellants is higher, the economical efficiency is better, and the dual-mode space nuclear energy propulsion system can serve as a priority choice of future spacecraft propulsion power.

    本发明公开了一种双模式空间核能推进系统,包括以氢工质作为推进工质的核热推进子系统和以氦气‑电推进剂混合气体为冷却工质的核电推进子系统;本发明通过核反应堆系统加热氢工质和混合气体闭式回路,由缩放喷管和电推进器喷射推进剂工质实现动力推进。本发明结合了核热推进与电推进技术的优势,提供一种新型的双模式空间核能推进系统,可实现推力范围毫牛到百千牛级别,推进剂的利用效率更高、经济性更佳,可作为未来航天器推进动力的优先选择。
