ABSTRACT:
An airfoil having a trailing edge flap assembly comprising a fore flap and an aft flap. A fixed mounting structure is positioned below the flaps when in their stowed position, and there is a first common link pivotally connected to the mounting structure and to each of the two flaps. A second link interconnects the mounting structure with the fore flap, and a third link connects a mounting arm of the fore flap to the aft flap. Thus, the common link forms with the second link and upwardly extending four-bar linkage to move the fore flap to its deployed position, and the common link forms with the third link a second upwardly extending four-bar linkage which deploys the aft flap to its extended position.
