ABSTRACT:
A wing structure including an assembly which is basically constituted of a main airfoil and a lift augmenting device in the form of a flap articulated to the airfoil so as to facilitate a high degree of lift to be imparted to the wing responsive to deployment of the flap. More particularly, there is disclosed a novel configuration of a trailing edge flap for a wing structure, wherein the upper surface of the flap is imparted an out-of-contour or curvilinearly raised configuration during periods of being stowed in the main airfoil whereby upon deployment of the flap into its deflected operative position will enhance the ability of the flap to derive an improvement in lifting capability and efficiency in comparison with presently conventional high lift trailing edge flaps. Also disclosed is a method of augmenting the high lift capabilities of trailing edge flaps which are operatively articulated to the main airfoils of aircraft wings so as to provide for an improved overall lifting characteristic for the aircraft wing structure.
