摘　　要：与通常的氢氧发动机相比,采用原子氢推进剂可以使比冲提高几百秒。通过介绍运载火箭采用原子氢推进剂的发展前景、原子氢推进剂火箭的起飞质量和干重,以及原子氢推进剂火箭设计的最佳方案,在比较宽的混合比范围、固氢颗粒中原子态含量范围、液氦载体含量范围估算火箭发动机性能,可以得到混合比为0时,作为单元推进剂的火箭起飞质量最低。原子氢推进剂以其优良的比冲性能给航天运载器带来质的飞跃,但对低温技术提出挑战。Compared with the usual hydrogen-oxygen engine, the atomic propellant engine can improve specific impulse for hundreds of seconds. In this article, the prospect of launch vehicle with atomic hydrogen propellant was analyzed, the take-off mass and dry weight of atomic propellant launch vehicle were estimated, and an optimal solution of the atomic propellant hydrogen rocket was put forward. Also, the rocket engine performance was estimated in a wide range of mixing ratio, atomic state content of solid hydrogen particles, and content of liquid helium carrier. As a monopropellant, atomic hydrogen propellant can realize a lowest rocket take-off mass when the mixing ratio is zero. Atomic hydrogen propellants may bring a revolutionary leap to launch vehicle, but issue the challenge in cryogenic technology.
