Abstract

There is disclosed a spoiler for wings, in particular of planes, which spoiler is unfoldable during the landing and take-off of the plane or the like and retractable during cruising. In order to provide for enhanced aerodynamic conditions during landing and taking off without deteriorating the aerodynamic conditions during cruising, a structural member preferably made of a composite material and, in particular, carbon fiber reinforced plastic is arranged on the trailing edge of the spoiler, viewed in the direction opposite to the flight direction. The structural member, during landing or taking off, in the unfolded state of the spoiler with the landing flaps extended reduces the gap formed between the trailing edge of the spoiler and the surface of the landing flap and, during cruising, with the landing flap pulled in and the spoiler retracted abuts on the surface of the landing flap.
