Abstract

Disclosed is a wing (3) for an aircraft (1), comprising a main wing (5) and a leading edge high lift assembly (6) comprising a slat (7), and a connection assembly (9) movably connecting the slat (7) to the main wing (5), such that the slat (7) is movable between a retracted position (11), a first extended position (13), and a second extended position (15), wherein the connection assembly (9) comprises an elongate slat track (17) that extends along a track longitudinal axis (19) between a first end (21) and a second end (23) and has an intermediate portion (25) between the first and second ends (21, 23), wherein the first end (21) and/or the intermediate portion (25) of the slat track (17) is mounted to the slat (7), wherein the slat track (17) is mounted to the main wing (5) by a roller bearing (27) such that the slat track (17) is movable along the track longitudinal axis (19), wherein the roller bearing (27) comprises a plurality of bearing units (34a-c), each of the bearing units (34a-c) being mounted to the main wing (5) and having a bearing surface (22) for engaging an engagement surface (35) provided on the slat track (17), wherein the plurality of bearing units (34a-c) comprises at least a first end roller unit (34a) and an intermediate roller unit (34b), wherein the plurality of bearing units (34a-c) are positioned such that, relative to the track longitudinal axis (19), the intermediate roller unit (34b) is positioned between the first end roller unit (34a) and the second end (23) of the slat track (17). The object to provide a wing having a beneficial ratio of aerodynamic performance and noise generated by extension of the slat, is achieved in that the slat track (17) and the roller bearing (27) are configured such that in the retracted position (11) and in the first extended position (13), the slat (7) rests against the main wing (5), whereas in the second extended position (15), a gap (37) is formed between the trailing edge of the slat (7) and the leading edge of the main wing (5).
