Abstract

1296994 Variable camber aerofoils; hydrofoils DEFENCE SECRETARY OF STATE FOR 26 May 1970 [2 June 1969] 27787/69 Headings B7A and B7G A fluid dynamic structure has a skin supported on rigid internal structure 45, 47 with a portion 46 of the skin being supported by movable support means 49, 51, and an hyraulic jack 56, 57 which moves the support means 49, 51 and flexes the skin portion 46 to change the profile of the structure. The skin portion 46 forms the leading edge of an aircraft wing 44 and is secured to a frame 49 and pivotally connected to a number of movable arms 51 all of which are pivotally mounted on rigid structure 47. The hydraulic jack 56, 57, which has a power connection 59, is also pivotally mounted on structure 47 at one end, and at the other end it is pivotally attached to a crank 54 on frame 49 so that extension of the jack causes the frame to rotate and the wing leading edge to bend. The skin 46 has rollers 61 running on a track 62 fixed to the main wing 44 so that it can slide over the main wing. In another embodiment, Fig. 5 (not shown), the movable arms, frame and jack are mounted on a carrier (75) supported by trunnions (80) running on a fixed track (81) and moved by a second jack (78) so that the leading edge portion may be extended forwardly of the main wing as well as being bent. The invention may be applied to hydrodynamic as well as aerodynamic structures.
