Geometric model for automated multi-objective optimization of foils

Participants : Elisa Berrini, Bernard Mourrain.

The work in [18] describes a new generic parametric modeler integrated into an automated optimization loop for shape optimization. The modeler enables the generation of shapes by selecting a set of design parameters that controls a twofold parameterization: geometrical - based on a skeleton approach - and architectural - based on the experience of practitioners - to impact the system performance. The resulting forms are relevant and effective, thanks to a smoothing procedure that ensures the consistency of the shapes produced. As an application, we propose to perform a multi-objective shape optimization of an AC45 foil. The modeler is linked to the fluid solver AVANTI, coupled with Xfoil, and to the optimization toolbox FAMOSA.

This is a joint work with Régis Duvigneau, Matthieu Sacher, Yann Roux.
