International audienceAerostructural optimization is a keystone process to concurrently improve aerodynamic performance and reduce the structural mass of an aircraft. However, gradient-based multidisciplinary design optimization is efficient only if the computation of gradients is fast and accurate. To this end, we propose two high-fidelity aerostructural gradient computation techniques for strongly coupled aeroelastic systems. In the specific context of this work, we focus on design variables affecting structural stiffness only. Scalar objective functions like aerodynamic performance criteria are considered, as well as a field of structural grid forces. The most intrusive technique includes well-established direct and adjoint formulations ...
