Abstract

An aircraft wing has upper and lower booms extending in the direction of the span at the deepest portion of the wing, and two systems of intersecting bracing members arranged with their greater depth normal to the surface and with their neutral axes in geodetic lines, the members being rigidly secured together at their intersections and also rigidly secured to the booms. The upper and lower booms may be interconnected by Warren bracing or left free to enable an outer section of wing to telescope within the inner section. The two systems of bracing d, e are in short lengths of channel section material with the webs normal to the wing surface, the ends of the webs being bent and secured to diametrically opposite points of short tubes f2, Fig. 8, and the flanges being secured to upper and lower plates f. Where the bracing intersects the booms still shorter members d4, d5, e4, e5 are secured to pressed metal pieces g, Fig. 6, slid over the boom and having bent portions g3, g4 secured thereto. Stiffening flutes g5 in the sides of the members g transmit the thrust. Where the bracing meets the leading and trailing edges the ends of the members d, e are received in channel members h, h1, Fig. 5, connected by Warren bracing and by vertical plates h2 to which brackets h3 are riveted.
