Rapid Indirect Trajectory Optimization of a Hypothetical Long Range Weapon System

Abstract

This investigation illustrates that complex, highly constrained hypersonic trajectory optimization can be performed for long range weapon systems using indirect optimization methods. It is shown that initial guesses to the optimal solutions can be effectively constructed using analytic ballistic trajectory solutions. The evolution to complex optimal trajectories from these initial guesses is made possible by overcoming the historical challenges of indirect optimization methods in a largely automated approach. The manner in which indirect mathematical information is integrated into the automated design methodology to solve this type of problem is described. Example mission design scenarios illustrate the speed of the methodology and quality of the optimal solutions to support practical aerospace conceptual design studies.
