TRANSVERSAL BUTT STRAP AND METHOD FOR CONNECTING TWO ESPECIALLY WOUND CFK FUSELAGE SECTIONS IN ORDER TO CREATE A FUSELAGE CELL

摘要

The invention relates to a transversal butt strap (1, 19, 37) for producing a fuselage cell of an aircraft, by connecting a plurality of CFK fuselage sections (5, 26, 27, 43) produced especially by a winding method and respectively forming a transversal seam. The flexible transversal butt strap (1, 19, 37) is multi-layered, i.e. it comprises a plurality of strap segments (7-9, 20-23, 38-40) arranged one over the other, each strap segment (7-9, 20-23, 38-40) comprising a plurality of longitudinal slits (10, 11, 44, 45) that can respectively perform slight radial bending movements in order to generate a tolerance compensation in the radial direction between the fuselage sections (5, 26, 27, 43) to be joined together. A sliding movement is performed between the partial straps (17,18, 50, 51) of the strap segments (7-9, 20-23, 38-40) arranged one above the other, in the axial direction of the barrel-shaped fuselage sections (5, 26, 27, 43), and the ends (5, 26, 27, 43) of the fuselage sections (5, 26, 27,43) are bezelled (35, 36) on the inside thereof. The invention also relates to methods for creating a connection between two CFK fuselage sections (5, 26, 27, 43) preferably produced by a winding method, using a transversal butt strap (1, 19, 37) according to the invention.
