Planes and wings, construction of.—An aeroplane wing is composed of a number of indeformable sections which are threaded on a spar or spars and are connected together on assembly by rivets or similar means. In each section 3 a covering of sheet metal or plywood, stiffened by corrugations or ribs, is fixed to the leading edge member 4 and to a sectional dummy spar 13 or to the trailing edge if no aileron is fitted at that point. Marginal angle strips 6 form a means of attachment for sheet‐metal plate ribs 7 which close each section. These plate ribs are strengthened by upright members 8 and are pierced with apertures 9 for the insertion of spar 1. The flanges of the spar 1 are accommodated in channel guides 10 riveted to the inner faces of the covering. Each section is threaded along the spar and secured by angle plates 11 riveted to the plate ribs, and to gussets 12 riveted to the spar web. The marginal angle strips 6 of adjacent sections are riveted together and the lading and trailing edges connected up to complete the assembly.
