Abstract
An aircraft wing including: a wing structure supporting a wing cover, the wing cover having an outer aerodynamic surface, which forms part of an aerofoil profile of the wing, and a recess stepped back from the wing aerofoil profile; and a spoiler device includes a spoiler coupled to the wing structure by a spoiler actuation mechanism for moving the spoiler between a retracted position and a deployed position, the spoiler having a surface which follows a contour of the wing aerofoil profile and where the spoiler is housed entirely in the recess when the spoiler is in the retracted position, and wherein the spoiler surface is extended away from the wing cover when the spoiler is in the deployed position.

An aircraft wing comprising:
- a wing structure supporting a wing cover, the wing cover including an outer aerodynamic surface which forms part of an aerofoil profile of the wing and a recess stepped back from the wing aerofoil profile;
- and
- a spoiler device comprising a spoiler coupled to the wing structure by a spoiler actuation mechanism configured to move the spoiler between a retracted position and a deployed position,
- wherein the spoiler includes a surface which follows a contour of the wing aerofoil profile,
- wherein the spoiler is housed entirely in the recess when the spoiler is in the retracted position, and
- wherein the spoiler surface is extended away from the wing cover when the spoiler is in the deployed position.
An aircraft wing comprising:
- a wing box including a front spar, an upper wing cover an a lower wing cover, wherein the upper wing cover and the lower wing cover form a portion of an aerodynamic profile of the aircraft wing;
- a spoiler panel seated in a recess of the upper wing cover while the spoiler panel is in retracted position and the spoiler panel and the recess extend in a spanwise direction of the wing box;
- and
- a spoiler actuation mechanism including a linkage having a first end coupled a portion of the wing box between the upper wing cover and the lower wing cover, wherein the spoiler actuation mechanism is configured to move the spoiler panel from the retracted position to a deployed position above the upper wing cover,
- wherein an upper surface of the spoiler panel follows a contour of the aerofoil profile while the spoiler panel is in the retracted position,
- wherein the spoiler panel is housed entirely in the recess when the spoiler is in the retracted position, and
- wherein the recess setback inward into the wing box with respect to the aerodynamic profile formed by the upper wing cover.
