ABSTRACT:
A fixed wing is provided and includes an upwardly opening recess formed therein and extending along the trailing marginal edge portions of the wing. A flap is provided and mounted from the wing for shifting relative thereto between a first lower retracted limit position at least substantially fully received in the recess, and an elevated position displaced upwardly above the upper surface of the wing with the flap disposed at an angle of attack greater than the angle of attack of the wing. A closure panel is mounted in the recess below the flap for upward movement to a closed position at least substantially closing the recess at the upper portion thereof upon upward movement of the flap to its elevated position and the portion of the wing defining the forward portion of the recess in which the flap is receivable includes a trailing flexible flap member which overlies the forward edge of the flap when the latter is in the closed position and pass which the leading edge of the flap is movable, as a result of deflection of the flap member, upon movement of the flap back and forth between the retracted and elevated positions thereof.
