Thrust-Coast-Thrust Sequence

Author: Tianjiang Shuo

Definition

A pre-structured flight profile for Earth-moon transfers consisting of a continuous-thrust Earth-escape spiral, a thrust-free translunar coast, and a continuous-thrust moon-capture spiral. The three segments are joined via state-matching conditions. Compared to continuous-thrust profiles, the coast phase significantly reduces propellant consumption.

Application Value

Thrust-Coast-Thrust Sequence plays a critical role in trajectory optimization and multi-body dynamics analysis for solving complex trajectory design problems.
