Platform for multi-model design

This paper introduces a global platform for the simulation and the design o f multi-model configurations. Fluid-structure interaction and optimization procedures are coupled with turbulent incompressible and compressible flow solvers in order to treat complex aerodynamics problems. First, the equations used in modeling the fluid and the structure are prese nted, as well as the numerics used in the solvers. Then follows the descrip tion of our optimization framework, the gradient approximation and several optimization methods we employed. The applications concern shape optimization for turbomachinery blades and a ircraft airfoils and shape optimization coupled with aeroelasticity in aero nautics. The platform is dedicated to the treatment of realistic problems a nd serves as a powerful tool for design in industrial environments.
