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.

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 first and second track mounting portions at transversely spaced first and second track mounting locations; 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 first and second substantially longitudinally aligned track members operatively connected to said first and second track mounting portions, for longitudinal and rotational movement relative thereto, each track member having a forward end and a rear end, said track members being characterized in that with the flap member in the first position, the rear end of each track member is at its related track mounting location, and with the flap member in its third position, the forward end of each track member is at its related track mounting location; d. actuating means operatively connected to said flap member and arranged to move said flap member substantially longitudinally between said first and second positions with relatively less rotational movement of the flap member so as to cause substantial Fowler motion of the flap member, and to move said flap member between said second and third positions positions with relatively greater downward rotational movement of the flap member in a manner to cause relatively less Fowler motion; e. said flap member having a first forward connecting member and a second rear connecting member, connecting said flap member to said first track member at first and second connecting locations, respectively, said flap member having a third forward connecting member and a fourth rear connecting member, connecting said flap member to said second track member at third and fourth connecting locations, respectively; f. said first and third connecting members being arranged to permit relative rotational movement between said flap member and said first and second track members at said first and third connecting locations, respectively, said second and fourth connecting members being arranged to permit relative rotational movement and also relative transverse movement between said flap member and said first and second track members at said second and fourth connecting locations, respectively.
