The aerodynamic noise generated by the lift augmenting1 and landing gear systems constitutes the major source of the exterior noiseof jumbo jets in the approach phase. The numerical forecasting of this noise therefore represents a crucial factor for manufacturers
Velocity measurements using high-repetition-rate stereoscopic PIV make it possible to observe the large scale dynamics ofjet turbulence in a wind tunne, opening the way to progress in the understanding ofjetnoise generation... These interactions are key elements in the generation ofjetnoise in aeronautic engines
