ABSTRACT OF THE DISCLOSURE WING LEADING EDGE ARRANGEMENTS FOR AIRCRAFT The invention concerns a wing leading edge arrangement for aircraft in which a slat 10 is provided forwardly of a fixed leading edge 11 and is movable between a retracted configuration in which it lies closely adjacent the fixed leading edge 11 and a deployed configuration in which it is spaced from the fixed leading edge 11 to define a slot 13. The slat 10 includes attachment means 14 to two chordwise extending support tracks 12 slidably mounted on the leading edge 11. An aperture 22 in the leading edge skin 23 accommodates the attachment means 14 when the slat 10 is retracted. A shutter arrangement 27 mounted within the fixed leading edge is movable between an aperture closing position when the slat is deployed and a retracted position when the slat is stowed. The shutter arrangement 27 includes a pair of shutter doors 27A, 27B having surface profiles generally conforming to the profile of the fixed loading edge 11 and being sized, in totality, so as to be capable wholly to close the aperture 22; parallel motion linkage (34-37, 42) mounted in the leading edge and connected to the shutter doors; and springs 45 for urging the shutter doors 27A, 27B to move between retracted and deployed positions.
