ABSTRACT:
An arrangement for suppressing aerodynamic noise generated by cavity effect interaction between a wing flap shroud and one or more partially deployed trailing edge flaps. Noise suppression vanes are so positioned with respect to the shroud lower trailing edge and the leading edge of the wing flaps at partial deployment that eddies and vortices resulting from airflow separation at the shroud lower surface are diverted sufficiently by the noise suppression vanes to avoid significant noise inducing impingement of the separated flow on the flap leading edge.
