| Popis: | International audience; For aircraft in approach and landing operations, when the engines are in idle regime, airframe noise becomes predominant. High lift devices, namely the leading edge slats and the trailing edge flaps, deployed to increase lift at low speed, represent one of the main contributor to the airframe noise.A large number of numerical studies have addressed such configurations in the past, using unsteady computations based on either zonal RANS/LES [1-4] or hybrid RANS/LES [5-12] approaches. However, despite the advanced under-standing of flow features, these studies suffered from the lack of mixed experi-mental measurements to validate conjunctively the aerodynamics and the aeroa-coustics. Among the reasons, one can point out the different stream deflections, with direct consequences on the flow around the wing, when such deployed configuration is measured in a closed test section (for aerodynamics) or open test section (for aeroacoustics) measurement wind tunnels. |
