Velocity Maximum

Author: Tianjiang Shuo

Website: https://cislunarspace.cn

Definition

The point along a trajectory where the speed reaches a local maximum. Applying a deceleration maneuver at this point maximizes the change in Jacobi constant for a given velocity increment, thereby lowering the spacecraft's energy at minimum cost. This is the location where the second impulse is applied in the four-impulse low-energy transfer scheme.

Application Value

Velocity Maximum plays an important role in orbit maneuver design, analysis, and transfer planning for cislunar missions.
