Abstract
This paper presents some recent achievements towards high-fidelity aero-structure gradient computation with respect to structural design variables. A first part details the new module developed and implemented in the Onera elsA software capable of computing aero-structure gradients using intrusive direct and adjoint methods. In a second part an alternative improved uncoupled non-intrusive approach is proposed. Both approaches are evaluated and compared on the Onera M6 wing considering criteria such as accuracy, efficiency, and applicability on practical industrial problem.
