471,514. Aircraft structures. STIEGER, H. J. Feb. 4, 1936. No. 3347. [Class 4] Aircraft structures are built up of previously constructed members comprising a skin part and stress-carrying structure, the structures being completed by interattaching the members in a surface containing the neutral axis of the completed structure. In one form, a wing is built up of components comprising spar parts 1A, 3A, ribs 4A, 4, 4B, and metal skin 5. The appropriate spars are butt-jointed together and the structure is completed by a nose fairing 8 which may be secured by wire pins 9. A tank 10 may be housed in the wing. In a modification, the skin is supported by a corrugated sheet attached to a capping strip secured to brackets which are connected to the lap-jointed spars. In a further modification, the spar is formed by securing flange portions, which may be built up of laminations, to a lightened web. A wing flap may be hinged to the trailing edge of the wing. A fuselage may similarly be built up of components 71, 72 butt jointed as at 73. In a modification of this form, a bomb 88 may be housed in the fuselage, hinged doors 89 being provided. A tapering fuselage may be built from blanks of different dimensions pressed to shape by a single set of tools. The fuselage may be built up of quadrantal portions, and decks and floorings may be incorporated in the stiffening members. A seaplane float may be constructed in a similar manner.
