Optimization and Model Order Reduction on Launch Vehicle Aerodynamic Design

Author(s): 
Cedric Dupont (CT Paris, France)

This paper presents the methodology used to assess aerodynamic calculations of a launch vehicle and optimize aerostructures. The workflow integrates an automatic mesh procedure, pre-treatment calculations, CFD calculation and post-processing, all integrated into HADES optimization environment based on modeFRONTIER. This process has multiple objectives: define the aerodynamics database thanks to the Design of Experiments Algorithms; optimize structural mass and geometry of the launch vehicle; elaborate surrogate models for aerodynamic coefficients evaluation.
