摘　　要：探索了一种高比推力、高有效载荷的D-3 He聚变燃料火箭的可行性,对化学燃料火箭、裂变燃料推进器与聚变燃料火箭发射时的有效载荷份额与飞行使命的时间之间的折衷关系做了比较。从能量守恒关系分析了D-3 He聚变燃料火箭先进性的基本原理,以及运用D-3 He聚变反应作为空间飞行推进单元的优点。除了月球表层土中有丰富的氦-3资源外,也对地球外层空间中其余行星,如金星、水星和火星上的3He资源作了定量的估算。The feasibility of high specific impulse and high payload propulsor with D-3 He fusion fuel has been investigated. The comparisons of tradeoff relation have been made of their payloads at the takeoff time and fly mission durations among chemical fuel rocket, fission fuel rocket and fusion fuel rocket. Based on the power balance relation the basic benefit of D-3 He fusion fuel rocket and the benefit of propulsion u-nit for space flight by using D-3He fusion reaction have been analyzed. Besides the abundant 3He resources in the lunar regolith, the resources on the other planets in the universe, such as Venus, Mercury and Mars are also taken into investigation numerically.
