Definition

A mathematical procedure of scaling variables in physical equations using characteristic quantities (characteristic mass, length, time) to eliminate units and render the equations in nondimensional form. In the CR3BP, the total Earth-Moon mass, Earth-Moon distance, and reciprocal of the orbital angular velocity are typically used. Benefits include revealing the intrinsic scale of the problem and improving numerical stability.

Application Value

该模型是分析地月空间动力学、设计低能量转移轨道的基础工具。
