text: In an airfoil and slat assembly, the slat being arranged when closed to seat upon the nose of the airfoil with its trailing edge portion overlying the upper forward s-urface of the airfoil and with the upper surface of said trailing edge portion substantially flush with the upper surface of the airfoil aft of the slat, said upper forward surface of the airfoil comprising a resilient strip secured at its forward edge to the body of airfoil, stop means for limiting outward flexure of said strip to a position wherein its rear edge portion is adjacent said upper aft surface of the airfoil whereby when the slat is open a substan tially continuous surface-is presented to air flow ing over the airfoil from the slot between the slat and the airfoil, said strip being flexed away from said stop means to displace said rear edge portion thereof inwardly from said upper aft sur-- face of the airfoil upon closing of the slat for providing a recess in the airfoil to accommodate the thickness of the trailing edge portion of the slat.
