Abstract

This study explores the application of analytical methods to the optimization of trajectories for various types of aerospace vehicles. While numerical methods have dominated recent approaches to trajectory optimization, this work revisits and extends analytical techniques, particularly those from singular perturbation theory. This report examines the application of these techniques to atmospheric re-entry trajectories. First, after a literature review, classical results on the analytical solutions of the trajectory are reproduced and their limitations and advantages are evaluated. Subsequently, a constructive method to reformulate the re-entry dynamics in a multi-scale fashion was successfully implemented. Finally, an analytical closed-form expression for an optimal control law was derived. Finally, this report suggests several potential directions for future research.
