Abstract
The invention relates to a leading-edge slat actuating system comprising an intermediate slat having a trailing edge and hingedly connected to a beam fast with the main wing, a front slat hingedly connected to the beam and a leading edge hingedly connected to the front slat, characterized in that the system includes: a first jack having one end hingedly connected to a non-moving point on the wing structure and its other end hingedly connected to a moving point fast with the front slat; two rods on either side of the jack, having their hinge-points located on the one hand on the leading edge of the front slat, in an outer part of the undersurface thereof, and at non-moving points on the beam on the other; a second jack having one end hingedly connected to a non-moving point on the wing structure and its other end hingedly connected to a point moving with the trailing edge of the intermediate slat, the jacks and rods being so arranged that when the jacks are in their extended position the slats are extended to form two slits one of which lies between the intermediate slat and the wing and the other between the front slat and the intermediate slat.
