Embodiment Construction

[0043] First refer to figure 1 , shows a commercial airliner 1 with a fuselage 2 part of which is at figure 2 is shown in more detail in , where the fuselage section 2 is viewed from the inside of the passenger aircraft.

[0044] The fuselage 2 generally includes a skin 3 and a fuselage frame 4, the inner surface 3a of the skin 3 supports the fuselage frame 4 in a fixed manner, and a single fuselage frame in the fuselage frame 4 is figure 2shown in . This frame 4 extends over all or part of the periphery of the fuselage in a transverse plane of the aircraft, ie a plane orthogonal to the direction 6 corresponding to the longitudinal and axial direction of the passenger aircraft. Each frame may be made in one piece or formed using several frame elements / sections each of which forms only a single corner sector of the frame, wherein these elements are then end-to-end Assemble end-to-end. The frame elements generally extend over an angular sector of the order of 30° to 120°. ...

Abstract

In order to reduce the time and cost of manufacturing an aircraft fuselage, the invention provides a tool (30) for positioning a mounting fixture (20) for attaching a fuselage frame element (4) Attached to the fuselage skin (3) and / or attached to the stiffeners (8). According to the invention, the tool comprises a ramp (32) and several systems (34) for holding in place grippers distributed along the ramp, wherein each system (34) is comprising a movable device (36) and an adjusting device (46), wherein the movable device (36) is used to apply pressure to the ramp, and the adjusting device (46) is coupled to the movable device so that the movable device (36) can be adjusted Separation from the ramp (32).

Description

technical field [0001] The present invention relates to the field of aircraft fuselages and in particular to the field of positioning mounting fixtures for attaching aircraft fuselage frame elements to fuselage skins and / or to attachments fitted to the fuselage skins. Leather stiffeners. [0002] The invention finds particular, but not exclusive application in the field of commercial airliners. Background technique [0003] Aircraft fuselages are designed to withstand the loads caused by pressurization as well as the loads transmitted by the engines. [0004] To achieve this, the fuselage usually consists of a circumferential frame, also called a "ring frame", and an aerodynamic skin, sometimes called a "self-stiffening skin", attached to these circumferential frames And fitted with generally longitudinally extending stiffeners attached to the inner surface of the skin and commonly referred to as "stringers". [0005] The stringers can have different types of sections, fo...
