摘　　要：以推进技术对空间探测的重要性作为切入点,介绍核火箭发动机的总体分类,以及核热火箭发动机及核电火箭发动机的技术特点,并对其应用前景及未来发展方向作重点展望。未来,更有望采用由核热推进及核电推进组成的双模式推进系统;而核聚变推进技术同样也是一项重点发展方向,但考虑到当前的技术水平,该类推进方式尚处于理论研究阶段。而由核辐射引发的安全性问题,则是未来发展核火箭发动机时需要首先考虑的因素。Taking the importance of propulsion technology to space exploration as a starting point,the overall classification of nuclear rocket engines and the technical characteristics of nuclear thermal rocket engines and nuclear power rocket engines are introduced.and its application prospect and future development direction are emphatically prospected.In the future,it is expected to adopt a dual-mode propulsion system composed of nuclear thermal propulsion and nuclear power propulsion,and nuclear fusion propulsion technology is also a key development direction,but considering the current technical level,this kind of propulsion is still in the stage of theoretical research,and the safety problem caused by nuclear radiation is the first factor to be considered in the development of nuclear rocket engine in the future.
