Abstract
An airbrake located on the wing of an aircraft between a rear spar and a wing flap comprises two panels aligned with the upper surface of the wing when the airbrake is closed. In the open state or fully deployed position, the two panels are contiguous and behave as a single panel. However, in the intermediate states, the panel closest to the flap is deflected more than the other panel, so that a slot is formed between them. This slot makes it possible to significantly decrease turbulence on either side of the airbrake when the latter is used in low deflection flight.
Claims13
An airbrake adapted to be mounted along the upper surface of an aircraft wing, between a rear spar of the wing and a wing flap, said airbrake comprising a first panel adjacent said rear spar, a second panel between the first panel and the wing flap, and inclination control means for mounting and actuating the airbrake such that the first panel and the second panel form a contiguous portion of the upper surface of the wing when the airbrake is in a closed position and the first panel and the second panel are at the same angle and form a contiguous surface when the airbrake is in a fully deployed position but the second panel is at a greater angle than the first panel intermediate the closed and fully deployed positions forming a slot between said first and second panels.
