Definition

A strategy that matches the hyperbolic excess velocities (v-infinity) before and after lunar gravity assist to connect the LEO-to-LGA and LGA-to-DRO trajectory segments. It adjusts perigee parameters without changing the post-assist v-infinity magnitude, improving convergence rate by approximately 15 times.

Application Value

在v无穷匹配的设计与分析中，可用于优化转移方案，减少燃料消耗 该概念为地月空间任务设计提供了重要的理论基础 在实际工程中可用于轨道设计、任务规划或控制系统分析。
