Hypersonic Vehicle Analyses: The Needs and Challenges of Multidisciplinary Simulations

We conduct our analyses within the AAA Multidisciplinary Optimization framework using a Particle Swarm Optimization Algorithm. The core of the analysis involves a three-dimensional dynamics system of equations with weakly coupled heating. We have created a database of thousands of CFD calculations with Lemon to provide high-fidelity interpolated predictions of heating for trajectory constraints. To impose constraints, we utilize different cost functions for optimizing downrange and crossrange distances.

In this study, we are examining the effects of the chemistry model on trajectory design through constraints on heat transfer and air chemistry modeling.
