An air scoop assembly (72) that may be for a nacelle (60) of a turbofan engine (20) includes a surface (84) defining at least in-part a primary flowpath and a hood (74) formed to the surface and projecting into the primary flowpath. The hood includes a distal, leading, edge (82) that is irregular in shape thereby producing air vortices that shed from the leading edge and co-extend in a downstream direction with an airstream in the primary flowpath. The vortices are thereby controlled such that air flow disruption and undesired resonance is minimized or eliminated.
