Abstract

A flap comprises three or more pivotally inter‐connected spanwise strips forming an articulated unit pivotally attached along one edge 42 to the wing 1, the flap being raised or lowered by a series of radius rods 15, 16, 17, 18 actuated by a hydraulic jack 6, 7. The rod 6 of the jack carries a cross‐piece 9 to which rods 10, 11, 12, 13 arc attached. The rod 10 carries a member 31 to which the lower end of the radius rod 15 is pivoted, while the rods 11, 12, 13 carry further members 32, 33, 34 which successively engage blocks 24, 25, 26, to which the rods 16, 17, 18 are pivoted, when the hydraulic jack is extended. Projections at the upper ends of the members 31, 32, 33, 34 engage the rear faces of the radius rods when the flap is fully raised, FIG. 5. Manually operated rack and pinion, or screw drive, may be substituted for the hydraulic jack.
