[Class 4] [Also in Group XXII] In building aircraft components of which the surface exposed to the air comprises thin sheets of metal or other material of high tenacity supported on stiff longitudinal stringers and stiff transverse members or frames, straight lengths of stringers are secured to covering sheets along predetermined lines which remain straight when the covering sheets are curved to their final form. A fuselage designed' to have the maximum of developable surface and thus susceptible to construction by the method described, comprises a non-developable nose portion 1, a midship portion 2 which has developable sides but is cut away for cock-pit 4 and wing 3, a doubly-curved portion 7, and a second developable portion 5. Considering the formation of portion 5, a covering 11, Fig. 2, which may comprise longitudinally extending lap-jointed sheets is laid out on a flat surface and marked off to dimensions, the position of each stringer 12 at the large and small ends is marked and the marks joined by a straight line, holes are drilled along the lines and in the stringers and the latter then riveted in position. The stringers may be of any section and may be attached by passing the sheet through automatic riveting or welding machines. The covering-stringer units may be attached to a framework constituted by spars and ribs, e.g. in the case of a wing or control surface structure or may be assembled with structural elements to form a unit which bv assembly with similar units constitutes the body or body portion desired. Body section 5, Fig. 2, comprises covering units with Z- section stringers and angle-section edge members 13, constituting connecting means for the several units, Fig. 7. The covering units are shaped by connection at each end to a transverse frame comprising a contoured angle bar 14 or 15 which is either connected to a stiffening plate such as 40 or to a complete bulkhead. Intermediate frame pieces comprise a light angle bar 17, Fig. 4, bent to contour and adapted to contact the inner flanges of the stringers 12. The angle bars may be braced, as shown, by a chord member 18 and struts 19. Heavier frame pieces may be disposed at points of concentrated stress. The ends of the stringers are secured to the flanges of the end frame pieces by angle cleats. In the construction of wings and control surfaces, bracket pieces 21, Fig. 8, are attached to the booms of ribs which do not extend to contact the covering directly and are located so that their outer flange contacts that flange of the stringer which is connected to the covering and are secured by screws or externally closable rivets.
