Disclosed is a method for producing a fuselage airframe of an aircraft. Said method, in which several fuselage sections that are arranged one behind another are joined together, comprises the following steps: a) an external skin segment (1, 4, 9, 14, 20) is produced which encompasses a continuous longitudinal opening (3, 11, 22) on the bottom; b) the external skin segment (1, 4, 9, 14, 20) is expanded in order to introduce additional components; c) the external skin segment (1, 4, 9, 14, 20) is joined to an existing rigid fuselage section (23) such that a partial transverse seam (33) is formed; d) a prefabricated bottom shell (5, 17, 21) is placed in the longitudinal opening (3, 11, 22) to close the external skin segment (1, 4, 9, 14, 20); e) the partial transverse seam (33) is completed to form a transverse seam, and the bottom shell (5, 17, 21) and the external skin segment (1, 4, 9, 14, 20) are joined together such that at least two longitudinal seams (46, 47) are formed; and f) the floor frame (34) and the external skin segment (1, 4, 9, 14, 20) are joined together. |
