对“阿波罗”载人登月月地转移中途轨道修正进行了调研,并对月地转移中途轨道修正模型进行建模,并设计微分修正法进行求解。系统分析了月地转移初始轨道偏差对再入点偏差的影响,通过计算,给出修正初始偏差量所需要的速度增量大小。对于月地转移两次中途轨道修正的时刻,通过仿真分析给出了合理建议。
The “Apollo” manned lunar landing mid-course orbit correction was investigated, and mid-term orbit mid-term orbit correction model was modeled, and the differential correction method was designed to solve. The influence of the initial orbital deviation on the reentry point is systematically analyzed. The magnitude of velocity increment needed to correct the initial deviation is given by calculation. At the moment when the mid-course orbit correction is transferred twice on the moon, a reasonable suggestion is given through the simulation analysis.
