Aircraft`s e.g. twin-engine aircraft, wing arrangement, has zone including projection delimiting channel, where air flow is accelerated through channel and is evacuated in direction privileged under wing, between surface of wing and nacelle

摘要

The arrangement (1) has a wing (2) including proximal and distal ends, and a hooking pylon (4) of an engine (6) e.g. turbojet engine, suspended under the wing. The wing has a front zone (8) e.g. aerodynamic zone, situated toward the front with respect to a wing`s leading edge (10). The zone has a lateral projection (12) delimiting an air flowing lateral channel (14) by projecting toward the proximal end of the wing, where air flow is accelerated through the channel and is evacuated in a direction privileged under the wing, between a lower surface of the wing and a nacelle of the engine.
