Embodiment Construction

[0040] figure 1 An embodiment is disclosed showing a first aircraft part 1 coupled to a support structure 6 comprising a set of reference elements 5 and three receiver surfaces 3 with respect to three second aircraft parts 2 , in particular a set of reference surfaces, in particular three fittings adapted to be joined to three receiver surfaces 3 .

[0041] The reference element 5 will be used to correctly align the digitized receiver surface 3 with the computer design model (CAD) of the first aircraft part 1 and the second aircraft part 2 . Thus, said set of reference elements 5 cooperates in the correct alignment of the point cloud and the CAD model. Another possibility, although not preferred, is to position the reference element 5 directly on the first aircraft part 1 . The advantage of positioning the reference element 5 on the support structure 6 of the first aircraft part 1 is that no manipulation of the aircraft part 1 is required to position or remove the reference ...

Abstract

The invention provides a manufacturing and assembly method of parts of an aircraft. The method comprise comprises the following steps: providing a first aircraft part (1) comprising a receptor surface(3) on which a coupling surface (4) of a second aircraft part (2) is to be assembled, providing a model of the first (1) and the second (2) aircraft parts in its assembled position, the model of thesecond (2) aircraft part comprising machining allowances (5) in its coupling surface (4), digitalizing the receptor surface (3) of the first aircraft part (1), positioning the digitalisation in the computer model in the assembled position such that the digitalisation of the receptor surface (3) intersects the coupling surface (4) of the second (2) aircraft part, obtaining a model of the second part (2) in which the coupling surface (4) fits the digitalised receptor surface (3), mechanising the second aircraft part (2).

Description

technical field [0001] The present invention relates to a method and system for the manufacture and assembly of aircraft components which enable rapid manufacturing and reduce the need for jigs for performing the manufacturing and assembly operations. Background technique [0002] In the aviation industry, it is very common to assemble components in large structures with small tolerances, for example, this assembly is performed in horizontal stabilizers, wings or in the axis of rotation in the fuselage. [0003] Currently, to assemble these parts, jigs or tools with large stable welded structures are used, which are mounted and assembled with external verification systems such as laser trackers, micro-alignment telescopes, transport or theodolites. In some cases, photogrammetry, articulated coordinate measuring machines, lidar, or portable optical measurement systems are used. With these structures, the parts to be assembled are positioned at desired positions. [0004] Th...
