One-shot airfoil optimisation without adjoint
We propose a shape optimisation algorithm for aerodynamics in which the flow equation is solved progressively. A novelty is that this is done without an adjoint. Main ingredients are: divided differences for a simplified state system, and hierarchical parameterisation. Applications to inverse problems and shock reduction for transonic viscous airfoil flows are presented. (C) 2002 Elsevier Science Ltd. All rights reserved.
