Abstract
An aircraft wing and flap arrangement comprises a fixed wing (1) a flap (2) pivoted at (3) to the fixed wing and a variable camber upper surface member (6) anchored to the fixed wing and resiliently biased toward the flap at all times; a cam track (9) secured to upper surface member (6) and associated cam track engaging member (10) on an arm (11) secured to the flap to control movement of the upper surface member so that on relatively small deflections of the flap (2) the upper surface of the wing is substantially continuous, while on relatively large downward deflections the upper surface is urged, by cam track engaging member (10), away from the flap (2) to open a slot (12); the arrangement may include a lower surface member (14) which is urged towards the upper surface membr (6) on relatively large downward deflections of the flap (2).
