Abstract

The present invention relates to a device for attenuating the vortex wake generated in the tail section of an aircraft (100), the aircraft having at least one wing (108) and an afterbody (106) with an asymmetric cross-section that sharply decreases towards the top of the rear fuselage (112). The device is positioned downstream of the wing (108) of the aircraft (100), symmetrically relative to the longitudinal plane of the latter. The device comprises aerodynamic vortex-generating appendages (200) suitable for being deployed between a folded position where the aerodynamic appendages are folded substantially in the direction of the fuselage (110) and a deployed position calculated to generate vortex structures having an intensity and following a path that modify the local pressure field in order to interact with the vortex wake and attenuate it, and to move the upsweep vortices away from the longitudinal plane of the aircraft (100).
