20100088896 | MANUFACTURING PROCESS FOR A SECTION OF AIRCRAFT FUSELAGE IN COMPOSITE MATERIAL - The disclosed embodiments relate to a method for manufacturing an aircraft fuselage section of composite material that comprises the following operations manufacturing a one-piece section; cutting the section longitudinally; spreading apart two edges located on the two sides of the cut; reassembling the section and making a longitudinal joint with the two edges overlapping. The disclosed embodiments also relate to a section made in accordance with this method. | 04-15-2010 |
20100096501 | Primary structure for aircraft of composite material with improved crash resistance and associated energy-absorbing structural element - The disclosed embodiments relate essentially to a primary structure of an aircraft fuselage that has at least a first strut linked at one end to a crossbeam and at the other end to a reinforcing frame. A second strut has one end fastened to the structure below the end of the first strut, and another end linked to the first strut through an intermediate sliding linkage. A deformable member is linked to the struts so that in case of a crash, the compressive forces press against the second strut, so that the end of the second strut slides along the first strut so as to stretch the deformable member longitudinally to absorb the shock. | 04-22-2010 |
20100170987 | CENTRAL SECTION OF AIRCRAFT WITH VENTRAL OR BELLY FAIRING CAPABLE OF MOVEMENT - An aircraft center section includes a center part of an aircraft fuselage, a wing section, a center wing box installed at least partly in the fuselage and providing a junction between the wing section and the fuselage, and a ventral fairing partly enveloping the fuselage and the wing section, with the ventral fairing being attached directly to the wing section and to the fuselage by means of structural elements that can make the ventral fairing a working fairing. | 07-08-2010 |
20100170988 | SECTION OF AIRCRAFT FUSELAGE IN COMPOSITE MATERIAL WITH A CONSTANT INTERIOR PROFILE - The disclosed embodiments concern an aircraft fuselage section made of composite material with an internal skeleton having frames that form the radial structure of the fuselage and stringers that form the longitudinal structure of said fuselage, and a skin made of composite material, surrounding the internal skeleton, with said skin having an evolving thickness along a longitudinal axis X, with an approximately constant, regular interior profile. The disclosed embodiments also concern a process for manufacturing the skin of an aircraft fuselage section made of composite material, having a draping operation for strips of fibers precoated with resin around a mold, with the number of strips of fibers varying longitudinally depending on the area of the fuselage being considered so as to create a skin with an evolving thickness. | 07-08-2010 |
20100176241 | AIRCRAFT FRONT PORTION INCLUDING A CONCAVE BULKHEAD SEPARATING A NON-PRESSURIZED RADOME AREA AND A PRESSURIZED AREA - The invention relates to an aircraft front portion ( | 07-15-2010 |
20110260003 | AIRCRAFT SEAT ASSEMBLY STRUCTURE, AND FITTED FUSELAGE - An aircraft seat assembly structure ( | 10-27-2011 |
20120009372 | STRUCTURAL PANEL WITH INTEGRATED STIFFENING - The invention relates to the field of structural panels, more specifically, but not exclusively, to the field of aircraft fuselage panels. | 01-12-2012 |
20120104167 | FUSELAGE ELEMENT COMPRISING A FUSELAGE SEGMENT AND JUNCTION MEANS, FUSELAGE PORTION, FUSELAGE AND AIRCRAFT - The invention relates to a fuselage element ( | 05-03-2012 |
20130192045 | DEVICE AND METHOD FOR ASSEMBLING BRACKETS IN AN AIRCRAFT STRUCTURE - The invention relates to a positioning device for assembling parts on a structure. More specifically, the invention relates to a positioning device designed for assembling fixed brackets to an aircraft structure. A laser projector is fastened directly on the rigid aircraft structure; its position is therefore stable in relation to the latter, even if said structure undergoes slight deformations. The position of the projector is determined accurately by utilizing targets, which are also fastened to the primary structure. The invention also relates to a method for implementing this device. | 08-01-2013 |
