| 摘要: |
| 核热推进具有比冲高、推力大等特点，在载人深空探测和星际货运任务上具有广阔应用前景。核热推进技术的研发需要进行大量地面试验。首先回顾了美国与俄罗斯的核热推进地面试验技术的发展，对地面试验技术进行分类总结。然后基于一种小型核火箭方案，研究了燃料元件非核试验、燃料元件辐照考验试验和带核整机地面试验等关键地面试验技术，并提出了初步试验方案。最后对我国核热推进地面试验的发展提出了一些建议。 |

| Abstract: |
| Characterized by its high specific impulse and large thrust, Nuclear Thermal Propulsion (NTP) shows wide applications in deep space explorations and interplanetary cargo missions. Various ground tests are required to develop NTP technology. This paper first reviews technology development of NTP ground tests of the United States and Russia. Then, based on a small nuclear thermal rocket concept (CERMET-SNRE), technical options for some key tests such as non-nuclear test of fuel element, irradiation test of fuel element and NTP engine integration test are studied. Finally, some suggestions for the technology development of NTP ground tests are proposed. |
