Crossbar for creating a fuselage cell and method for connecting two in particular wound CFRP fuselage sections

摘要

Crossbeam lug (1, 19, 37) for producing a fuselage cell of an aircraft by connecting a plurality of CFRP fuselage sections (5, 26, 27, 43) produced in particular by forming a respective transverse seam (14, 28, 48) Crossbar (1, 19, 37) is multi-layered, that is, with a plurality of superimposed tab segments (7-9, 20-23, 38-40) is formed, wherein each of the tab segments (7-9, 20-23, 38 40) has a plurality of longitudinal slots (10, 11, 44, 45), each of which can independently make slight radial bending movements to effect a tolerance compensation in the radial direction between the fuselage sections to be joined (5, 26, 27, 43), in which a sliding movement takes place between the part flaps (17, 18, 50, 51) of the superimposed tab segments (7-9, 20-23, 38-40) in the axial direction of the barrel-shaped fuselage sections (5, 26, 27, 43), and wherein the ends (6, 24, 25, 41) de R fuselage sections (5, 26, 27, 43) inside chamfers (35, 36) may have; and method for producing a connection between two CFRP fuselage sections (5, 26, 27, 43) preferably produced in the winding process by means of a cross-joint flap (1, 19, 37) according to the invention.
