Embodiment Construction

[0035] An embodiment of an airframe structure testing device will now be described with reference to the accompanying drawings.

[0036] The test setup described below can test such as figure 1 The double curvature structure 10 is shown.

[0037] For example it concerns fuselage rings (couronne), such as figure 1 As indicated by the middle arrow, the fuselage ring has both longitudinal curvature and circumferential curvature.

[0038] The test rig can perform static tests, fatigue tests and damage tolerance tests on this structure.

[0039] In general, it applies forces that represent the forces experienced by an aircraft structure, especially tensile or compressive forces in the longitudinal direction, torsional forces relative to the longitudinal axis, or resulting from pressure differences between the interior and exterior of the structure pressure.

[0040] Of course, it must be possible to combine all of these types of forces exerted on the structure.

Abstract

The invention concerns a device for testing a fuselage structure (10) with longitudinal and circumferential curvature, comprising a set of means for applying forces (80) on the fuselage structure. It comprises a central shaft (20) extending in the longitudinal direction and at the center of the fuselage structure and adapted to be secured to the fuselage structure (10). The set of force applying means is mounted between the fuselage structure and supporting means (70, 90) integral with the central shaft (20). The invention is particularly useful for performing tests on an aircraft fuselage.

Description

technical field [0001] The present invention relates to testing devices associated with double curvature fuselage structures. [0002] In particular, the present invention aims to provide a testing device that can perform static testing, fatigue testing and damage tolerance testing of dual curvature, ie longitudinal and circumferential curvature, of fuselage structures. Background technique [0003] In fact, these fuselage structures are fuselage rings that are commonly used to manufacture the rear fuselage or the forward fuselage of an aircraft. [0004] It is known to use such test devices for applying forces to fuselage structures by means of force application systems, such forces representing the forces to which the fuselage structures are subjected when they are in use. These forces are generally tensile or compressive forces applied in the longitudinal direction of the structure, torsional forces along the perimeter of the structure, and pressures related to the press...
