Résumé

High Aspect Ratio (HAR) and Strut-Braced Wings (SBW) configurations represent promising avenues of research for meeting the challenge of reducing aviation carbon emissions. Both high and low fidelity models have already been developed for the abovementioned configurations as well as for the NASA Common Research Model (CRM) that will serve as a baseline for performance comparisons. These aero-structural models are then implemented within an in-house aeroelastic framework for analysis and optimization. High-fidelity models correspond to a RANS aerodynamic analysis associated to a 3D wingbox finite-elements (FE) analysis. Conversely, low-fidelity models resort to a VLM aerodynamic analysis associated to a 1D beam model FE analysis. The objective of this work is to use the so developed models to perform multidisciplinary optimization in order to assess performance improvements potential at preliminary design stage. Different levels of fidelity were developed with a multifidelity approach in mind for further developments. The use of a multifidelity approach makes it possible to reduce computational costs by mainly resorting to low-fidelity computations and only running high-fidelity computations when necessary. Then, aeroelastic optimization is carried out on a modified version of the CRM wing with a higher aspect ratio to study aerodynamic gains. Afterwards, a SBW configuration, here the PADRI geometry, is examined to evaluate its mass reduction potential in addition to the drag reduction provided by the increased aspect ratio. This work currently focuses on aeroelastic optimization using a single fidelity, but is to be further extended to a multifidelity approach.
