In this study the optimization of a complete 2D flying sails configuration is considered. An optimum shape design problem is then defined considering the maximization of the drive force on the sails, constrained by the heeling force, and complete flow modeling including turbulent effects. The corresponding numerical algorithm is based on a gradient descent method coupled with a discrete shape grid-point parameterization. The descent direction is obtained by an exact computation of an incomplete discrete gradient associated with a multilevel strategy. The numerical behavior of the present formulation has been illustrated by the optimization of real 2D configurations of an America’s Cup yacht.
