The invention discloses an earth-moon transfer orbit engine trial injection method. A midway correction strategy and trial injection requirements are jointly designed, and the engine trial injection requirements are met according to the optimal propellant principle on the premise of ensuring the near-moon point state of a transfer orbit. Engine trial injection is combined with midway correction ofearth-moon transfer, according to the position and speed data of the earth-moon transfer orbit at a certain moment, the midway correction control quantity is calculated, and the proper trial injection opportunity and strategy are determined in combination with the trial injection requirement of the engine, so different error conditions can be covered, the transfer track terminal target requirement and the trial injection requirement of the engine can be met at the same time, and good engineering operability is achieved.

    本发明公开了一种地月转移轨道发动机试喷方法,将中途修正策略与试喷需求进行联合设计,在确保转移轨道近月点状态的前提下,以推进剂最优的原则满足发动机试喷需求。将发动机试喷与地月转移中途修正结合,根据地月转移轨道某一时刻的位置速度数据,计算中途修正控制量并结合发动机试喷要求确定合适的试喷时机和策略,可以覆盖不同误差情况的推进剂最优试喷方法,可同时满足转移轨道终端目标要求和发动机试喷需求,具有良好的工程可操作性。
