Abstract

846,322. Aircraft. AUSTRALIA, COMMONWEALTH OF. Aug. 22, 1957 [Aug. 24, 1956], No. 26572 /57. Class 4. Means for augmenting the lift on an aircraft comprises at least one tubular member on the aircraft, one or more apertures on the wall of the member between the ends thereof, means for forcing gas into the tubular member, and means operable to effect retraction of the member into the aircraft and extension thereof from the aircraft. Fig. 2 shows an aircraft wing 22 having four tubes 23 extensible from the wing tip 28. Each tube, of aerofoil section, Fig. 6, is composed of two halves 24, 25 forming a slot 27 and bolted together at intervals. The tubes are connected to a plate 29 which nests onto the wing tip when the tubes are retracted. Each tube slides in pairs of bearing pads 30, 31 in the wing, the outermost pair supporting tapered channels 34, 35 which receive tapered projections 36, 37 on the tube when the tube is fully extended, and hold the tube rigidly. Each tube is connected for extension and retraction, by a lug 44 to a looped cable 41 connected to a cross-head 40 on a jack 38. The interior of each tube is connected by telescoping tubes 47 to a manifold 46 supplied with pressure gas from a stage of a jet propulsion engine. Extension of the tubes increases the lift by the aerodynamic forces on the tubes 23, and by the effect of the gases discharged from the slots 27, and also increases the lift of the main wing 22 by increasing the effective span. This construction may be applied to helicopter rotor blades. In alternative constructions, the tubes extend spanwise from the fuselage, and are retractable with their braces or ties by swinging about vertical axes through slots in the fuselage which are provided with adjustable fairing doors. The tubes may be of circular section, and may contain a row of holes instead of a slot. The movement of the tubes may be effected by electrical, hydraulic or pneumatic means, e.g. by the pressure of the gas admitted to the tubes.
