Gradient-based multi-disciplinary design optimization is actually efficient if gradients computations are fast and accurate enough. This paper presents two high-fidelity aero-structure gradient computation techniques for design variables impacting the stiffness of the structure. 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 Common Research Model (CRM) test-case considering criteria such as accuracy, efficiency, and applicability on practical industrial problem. Finally, preliminary results are presented on an inverse design problem. The final objective will be to match a target twist distribution on the Common Research Model wing using this new coupled gradient capability.<\/p>\n\n\n\n<p><a href=\"https:\/\/aerospacerepository.org\/wp-content\/uploads\/2024\/06\/IFASD-2017-002.pdf\">Read the full paper here<\/a><\/p>\n","protected":false},"excerpt":{"rendered":"<p><b>T.
