Multifidelity Optimization for High-Lift Airfoils

Autor: Timoleon Kipouros, Jean Demange, A. Mark Savill

Publikováno v: 54th AIAA Aerospace Sciences Meeting.

High-lift airfoil design is subjected to many constraints in terms of regulation and efficiency. It also involves complex flows that are still challenging to be estimated by Computational Fluid Dynamics. The time required to solve flow around a multi
