Abstract

An aircraft wing, including a main wing and a trailing edge high lift assembly movably arranged at a main wing trailing edge. The trailing edge high lift assembly includes a flap and a connection assembly movably mounting the flap to the main wing, the flap being movable between retracted and extended positions. In the extended position, a gap is present between a main wing lower rear panel and a flap leading-edge section. In the retracted position, the gap is closed or minimized. The flap is movable between the extended position, a first retracted position, and a second retracted position where the flap is moved beyond the first retracted position in a forward direction, and the wing includes a gap closing device configured to close or minimize the gap in both the first and second retracted flap positions, and to open the gap in the extended flap position.

A wing for an aircraft, comprising

a main wing, and
a trailing edge high lift assembly movably arranged at a trailing edge of the main wing, the trailing edge high lift assembly comprising
a flap, and
a connection assembly movably mounting the flap to the main wing, such that the flap is movable between at least one retracted position and at least one extended position,
wherein, in the at least one extended position, a gap is present between a lower rear panel of the main wing and a leading-edge section of the flap, and
wherein, in the at least one retracted position, the gap is closed or minimized,
wherein the flap is movable between at least one extended position, a first retracted position, and a second retracted position where the flap is moved beyond the first retracted position in a forward direction, and
wherein the wing comprises a gap closing means for closing or minimizing the gap in both the first retracted position and the second retracted position of the flap, and to open the gap in the at least one extended position of the flap,
wherein the gap closing means comprises a closing panel forming an extension of the lower rear panel of the main wing in a rearward direction,
wherein the closing panel is movable relative to the lower rear panel of the main wing between an elongated position and a shortened position, and,
wherein the gap closing means comprises at least one biasing member biasing the closing panel towards the flap in a same direction in both the elongated position and the shortened position.
