Abstract
A variable camber wing which may act as an aileron and as a slotted flap comprises a leading wing portion 1, a chordwise arm 4 tiltably mounted thereon and carrying a flap element 5, and an intermediate wing portion 6 slidably mounted on the chordwise arm by means of trackways 8 and associated rollers 9. An upper flexible but inextensible skin 11 is anchored to both the leading wing portion 1 and the intermediate wing portion 6. Downward tilting of the arm 4 from a median position causes the upper skin 11 to draw the intermediate wing portion 6 away from the flap element 5. On tilting through small angles, the intermediate wing portion 6 moves chordwise and the skin 11 slides over flap element 5 and defines a smooth and continuous surface between the leading wing portion 1 and the flap element, while on tilting through large angles, the intermediate wing portion moves upwardly relative to the flap element and lifts the skin 11 therefrom.
