Definition
The equivalent force arising from the non-inertial nature of a reference frame caused by a third body's gravitational pull on the central body. In the Earth-Moon rotating coordinate system, the Sun's gravitational pull on Earth alters the angular velocity of the rotating frame, introducing changes in Coriolis and centrifugal forces that constitute the indirect solar gravitational perturbation term.
Application Value
在间接引力的分析中,可用于轨道传播和机动设计,帮助工程师评估航天器在不同动力学环境下的运动特性 该概念为地月空间任务设计提供了理论基础,尤其在平动点轨道设计和低能转移分析中具有重要应用价值 利用间接引力进行轨迹优化,可以有效降低任务燃料消耗,提高任务经济效益 在任务设计中,间接引力的分析有助于理解航天器在复杂引力场中的行为,指导轨道保持策略的制定
