Definition

A strategy of multiple gravity flybys to adjust orbital phasing. At high Jacobi constants (low energies), phasing flybys of Earth or moon are the primary method for connecting Earth-moon transfers, gradually reshaping the trajectory through successive close approaches.

Application Value

该方法在轨道转移设计中被用于分析转移通道和能量最优轨迹，为低能量转移方案提供理论支撑。
