摘要
核热推进系统具有推力大、比冲高、能量转换效率高、长时间工作、推力可调、多次启动等优点,近年来再一次成为国际研究的热点。全文全面介绍了核热推进系统的类型与工作原理,总结了美、俄两国核热推进技术的发展现状及典型反应堆与燃料元件的设计方案和性能特点,梳理了存在的主要关键技术问题,并结合我国实际提出了发展建议。
Nuclear thermal propulsion(NTP)has been become the research hot spot in recent years,with advantages of large force,high specific impulse,high energy conversion efficiency,long operating time,adjustable thrust,and multiple restart.The types and operation principles of NTP were introduced comprehensively.The status of NTP development as well as the schemes and characteristics of the typical reactors and fuel elements in US and Russia were summarized,and the main key technologies of NTP were sorted out.Some development suggestions for NTP were put forward according to the actual situation in China.
