An airfoil having a trailing edge flap assembly comprising a flap member having a track mounted thereto. The track member is operatively connected to a slide-block which is in turn mounted to stationary structure. High Fowler motion is accomplished with this arrangement. In another embodiment the flap is additionally provided with a foreflap. In further embodiments, the flap assembly is provided additionally with aft flaps.

A flap assembly for an airfoil having a forward end, a rear end, a longitudinal axis and a transverse axis, said flap assembly comprising: (a) a mounting structure located at the rear end of the airfoil, said mounting structure having a track mounting portion at a track mounting location, (b) a first flap member having a stowed first position at the rear end of the airfoil, and movable rearwardly through an intermediate second position to a fully extended third position, (c) said flap member having mounted thereto a substantially longitudinally aligned track member operatively connected to said track mounting portion for longitudinal and rotational movement relative thereto, said track member having a forward end and a rear end, said track member being characterized in that with the flap member in the first position, the rear end of the track member is at the track mounting location, and with the flap member in its third position, the forward end of the track member is at the track mounting [position]location, (d) actuating means operatively connected to said flap member at a connecting location spaced forwardly of the forward end of the track member and having a fixed location relative to the flap member, said actuating means being arranged to move said connecting location substantially longitudinally along a first path [component]portion generally aligned with [the]a lengthwise axis of the track member to move said flap member between the stowed position and the intermediate position so as to cause substantial Fowler motion of the flap member with relatively little rotation of the lengthwise axis of the track member relative to the mounting structure at the track mounting location, and to move the connecting location along a second path portion, having a substantial upward path component to move the flap member between the intermediate position and the third position so as to cause relatively less Fowler motion with relatively greater rotation of the legthwise axis of the track member relative to the mounting structure at the track mounting location.
