Abstract

A method for joining two fuselage sections involves fastening a crossbeam to an elliptical interface frame to form an intermediate coupling assembly; temporarily fastening the intermediate coupling assembly to a planar mounting frame at a number of fixation holes formed in the planar mounting frame; temporarily fastening a buttstrap circumferentially around the interface frame; permanently attaching the intermediate coupling assembly and the buttstrap to a first fuselage section; disengaging the intermediate coupling assembly from the mounting frame; and permanently attaching a second fuselage section to the first fuselage section at the buttstrap.

First claim

What is claimed is:

1 . A mounting device for mounting an interface frame to a fuselage section, the mounting device comprising:
a planar mounting frame having a number of fixation holes formed therein, the mounting frame configured to be attached to an interface frame and a crossbeam of an intermediate coupling assembly; and at least one mounting beam extending substantially perpendicularly to the plane of extension of the mounting frame, the at least one mounting beam comprising a plurality of mounting beam attachment structures for attaching the mounting device to a mounting attachment beam of the fuselage section.

2 . The mounting device according to claim 1 , wherein the planar mounting frame comprises a rectangular or elliptical framework structure, and wherein the at least one mounting beam is attached to the rectangular or elliptical framework structure.

3 . The mounting device according to claim 1 , further comprising:
a mounting device carrier releasably coupled to the planar mounting frame, the mounting device carrier comprising mobility conferring equipment configured to move the mounting device carrier with the planar mounting frame and the at least one mounting beam substantially suspended in air.

4 . A method for joining two fuselage sections of aircraft or spacecraft, the method comprising:
fastening a crossbeam to an elliptical interface frame to form an intermediate coupling assembly; temporarily fastening the intermediate coupling assembly to a planar mounting frame at a number of fixation holes formed in the planar mounting frame; temporarily fastening a buttstrap circumferentially around the interface frame; permanently attaching the intermediate coupling assembly and the buttstrap to a first fuselage section; disengaging the intermediate coupling assembly from the mounting frame; and permanently attaching a second fuselage section to the first fuselage section at the buttstrap.

5 . The method according to claim 4 , wherein the interface frame comprises an outer frame member having a fastening flange for fastening the buttstrap.

6 . The method according to claim 4 , further comprising:
temporarily fastening the mounting frame to a mounting attachment beam of the first fuselage section.

7 . The method according to claim 6 , wherein the mounting attachment beam of the fuselage section comprises a seat rail of a floor grid in the first fuselage section.

8 . The method according to claim 4 , wherein temporarily fastening the buttstrap comprises tack riveting the buttstrap circumferentially around the interface frame.

9 . The method according to claim 4 , wherein permanently attaching the intermediate coupling assembly and the buttstrap to the first fuselage section comprises riveting the buttstrap to an inner wall of the shell of the first fuselage section.

10 . The method according to claim 9 , wherein permanently attaching the second fuselage section to the first fuselage section comprises riveting the buttstrap to an inner wall of the shell of the second fuselage section.

11 . The method according to claim 4 , wherein, after permanently attaching the intermediate coupling assembly and the buttstrap to the first fuselage section, longitudinal seams in the first fuselage section are completely riveted through.
