Abstract:

  • Optimization of vehicle shapes with performance and constraints based on full hypersonic trajectory.
  • Automated grid generation developed for entry capsules and winged entry vehicles.
  • Aerodynamic analysis with shielding includes integral treatment of body and wings.
  • The optimization is multi‐objective, based on particle swarm optimization.
  • Results include Pareto fronts of capsule and winged‐vehicle shapes to do trade‐offs.
