Device and method for reducing wake behind aircraft on approach

摘要

The device has a turbulence generator (9,10) in the area of the rear edge (3A,4B) of each aeroplane (1) wing (3,4), near the outer landing flaps (7,8) of the wings. The turbulence generators are arranged to generate an interfering turbulence (13,14) to cancel out the aeroplane turbulence (11,12). The turbulence generators are preferably formed as additional flaps, whose foot points are in an area of 10% of the half-width of the outer landing flap ends at the wing and 60% of the profile depth of the wing. The flaps can be folded away when not in use. Independent claims are included for an aeroplane incorporating the device and a method to reduce turbulence.
