ABSTRACT:
An airfoil having a trailing edge flap assembly comprising a flap member having a pair of tracks mounted thereto at spanwise spaced locations. Each track member is operatively connected to a slide member which is in turn mounted to a stationary structure. The flap member is attached to the two track members by means of pivotal links and ball joint connections to alleviate problems relating to wing deflection and also differences in linear movement of the flap member due to conical movement from the stowed to the deployed positions. Other embodiments show specific features relating to the actuating means, the track location, and the slide member location.
