气动磁镜聚变推进器的火星探测任务分析

将气动磁镜聚变概念拓展到空间推进器应用，分析了不同等离子体密度和氢推进剂质量流率下聚变推进器的比冲和推力变化范围，理论计算表明其比冲可达10 000 s以上，推力最高可达几十牛。在此基础上，进一步采用气动磁镜聚变推进器对地火转移任务进行了数值仿真。假设推进器初始质量为100 t，仿真结果表明:当飞行时间在282.42~639.76 d变化时，剩余质量从88.59 t提升至98.24 t。相关分析表明基于气动磁镜的聚变空间推进器通过调节比冲和推力组合方式，可以很好地满足未来火星载人和货运任务对飞行时间和有效载荷份额的不同需求，是未来高性能空间推进器发展的一种候选方案。 

Analysis of Mars exploration mission based on gas-dynamic-mirror fusion thruster

The gas-dynamic-mirror based fusion concept was expanded into space propulsion applications to analyze the range of specific impulse and thrust under different plasma density and hydrogen propellant mass flow rates.The theoretical calculation showed that the highest specific impulse can be above 10 000 s，and thrust up to dozens of Newton.On this basis，the fusion thruster based on the gas dynamic mirror was further used to simulate the Mars exploration mission.Assuming the initial mass of the thruster was 100 t，the simulation results showed that the residual mass increased from 88.59 to 98.24 t when the mission flight time varied from 282.42 to 639.76 d.The analysis showed that the fusion space thruster based on the gas dynamic mirror can well meet the requirements of future manned and cargo Mars missions by adjusting the specific impulse and thrust，making it an option for the development of high-performance space thrusters in the future.
