Abstract

615,284. Aerofoils. ARMSTRONG WHITWORTH AIRCRAFT, Ltd., SIR W. G., WOODHAMS, H. M., and LOCKWOOD, S. W. D. Aug. 1, 1946, Nos. 22904/46 and 16741/47. [Class 4] An aerofoil has at least the main portion of its air-swept surface formed of panels, of appropriate curvature, having inwardly projecting marginal flanges rigidly connected together by bolts, each of the panels being machined from a bar or plate of sufficient thickness for the formation of the marginal flanges. In the form shown in Fig. 1, upper and lower panels 21, 22 of light alloy are secured to spars 30, 31 and stiffeners 32 by bolts passing through spanwise flanges 25 and chordwise flanges 24 respectively. As shown in Fig. 3, the peripheral edges of the spars and stiffeners extend to the exterior surface of the aerofoil; alternatively, they may be recessed into the marginal flanges which are arranged to abut each other. The marginal flanges are stayed by triangular gussets 26, and the panels may also be provided with chordwise-extending reinforcing ridges between the flanges 24, also provided with similar gussets. The leading- edge portion 23 of the aerofoil is bolted to the spar 30, and the trailing-edge portion to the spar 31. Fig. 8 shows an alternative method of securing the leading-edge portion 37 in a recess 36 along the edge of the flange 25 to provide a flush joint. Such an arrangement may be used for attaching the trailing-edge portion, or for flush fitting access plates. The exterior surfaces of the panels are machined to the desired profile. Specification 615,275 is referred to in the first Provisional Specification.
