Aerodynamic Design of Airfoil Shape for Gust Generation in a Transonic Wind Tunnel

Design aérodynamique de profils pour la génération de rafale dans une soufflerie transsonique

Résumé

This article presents the aerodynamic design of the airfoil of the gust generator system being developed in the GUDGET project and conceived to generate high-amplitude gusts in a transonic wind tunnel. The system is made of vanes creating a flow deviation in turn by flapping around a rotational axis or by blowing air though a suitable sonic jet located close to the vane trailing edge. The airfoil shape optimization has been carried out using a design of experiment technique (DOE) and response surface optimization along with URANS CFD. The computational model has been preliminarily validated using data provided by ONERA for the baseline design at a lower Mach number (M=0.73) and then compared with the one actually required by GUDGET in the test chamber (M=0.82). All the cases have been optimized at a frequency of 40 Hz and then investigated at a frequency of 80Hz..
