Abstract
An air-redirection formation for a tip portion of an aerofoil such as an aircraft wing includes: a first portion, which includes a first surface which forms a continuation of the aerodynamic lifting surface of the wing, and which is for directing vortices away from the aerofoil; and a second portion, which is spaced from the first portion and which is positioned to generate uplift due to the directed vortices.

An air-redirection formation for a tip portion of an aerofoil which includes:
- a first portion, which includes a first surface which forms a continuation of an aerodynamic lifting surface of the aerofoil, and which is for directing vortices away from the aerofoil;
- and
- a second portion which is connected to the first portion by a connection structure which is canted downwardly and swept back, the second portion including a second surface spaced from the first portion by the connection structure and which is positioned to interact with the directed vortices
- wherein, defining a horizontal plane of the aerofoil by chords extending from the leading edge of the aerofoil to the training edge, the first surface is in the horizontal plane.
An aircraft having a plurality of wings, a tip portion of each of the wings including a respective air-redirection formation which includes:
- a first portion, which includes a first surface which forms a continuation of an aerodynamic lifting surface of the wing, and which is for directing vortices away from the wing, and
- a second portion which is connected to the first portion by a connection structure which is canted downwardly and swept back, the second portion including a second surface spaced from the first portion by the connection structure and which is positioned to interact with the directed vortices
- wherein, defining a horizontal plane of the wing by chords extending from the leading edge of the wing to the training edge, the first surface is in the horizontal plane.
