20100327111 | Electrical power transmitting telescopic strut - A telescopic strut comprises a plurality of hollow members arranged to slide one within another between a retracted and an extended position. Adjacent hollow members are arranged to be electrically connected by one or more electrical connector assemblies as the hollow members move between the retracted and extended positions. Each electrical connector assembly includes an electrically conductive pad on one of the hollow members which is in sliding contact with an electrically conductive strip on the other of the hollow members. The telescopic strut may be used to electrically connect a moveable control surface to a fixed aerofoil structure in an aircraft. | 12-30-2010 |
20110028061 | Adjustable shim - An adjustable shim comprises a stack of plies comprising plastics material reinforced with a three-dimensional fibre layer, the plastics material being flowable under compressive force prior to cure for adjusting the thickness of the shim. The shim may be used to fill a void between two structural components joined together. Also, a method of filling a void between two structural components using the shim. The shim is easy to handle, can easily be laid up to a variety of thicknesses, and is quick to cure (depending on the plastics material used). The three-dimensional fibre layers make the shim highly compressible prior to cure, and provide significant reinforcement to the plastics material of the plies to support compressive stresses in the shim post cure. | 02-03-2011 |
20110240200 | Method of forming a joint - A method of forming a joint between a first component and a second component, the first component comprising a plurality of layers of fibres impregnated with a thermosetting matrix. A welding interface element is provided with an array of pointed prongs. One or more of the layers of fibres are penetrated with the prongs, either before or after the fibres have been impregnated with the thermosetting matrix. The first component is cured by heating the thermosetting matrix after the prongs have been embedded. A thermoplastic weld is formed between the second component and the welding interface element. | 10-06-2011 |
20120037755 | WING STRUCTURE - A wing structure is provided, wherein the wing structure comprises; an upper covering, a lower covering, and a spar, the spar comprising; a spar web, an upper spar cap attached to the upper covering, and a lower spar cap attached to the lower covering, the wing structure also comprising a face spaced apart from the spar web extending between the upper and lower spar caps. The wing structure is arranged to contain fuel in a fuel containment area between the upper and lower coverings on one side of the spar web. The upper and lower spar caps extend from the spar web only on the other side of the spar web to the fuel containment area. | 02-16-2012 |
20120045613 | COMPOSITE STRUCTURE - A structure comprising a cured composite part formed from a series of plies of fibre-reinforced composite material; a doubler plate attached to the composite part by an array of pointed prongs which partially penetrate the composite part; and a hole passing through the doubler plate and the composite part. An interface plate carries the array of prongs on a first side and is attached to the doubler plate on a second side. | 02-23-2012 |
20130129526 | WRINKLE CONTROL METHOD AND TOOL THEREFOR - A method for forming a laminate component, the method comprising the steps of: a) providing a tool having a moulding surface; b) arranging a stack of ply layers on the moulding surface of the tool; and c) moulding the stack of ply layers over the moulding surface in a moulding process, wherein the tool has a wrinkle control feature in its moulding surface for managing the development of wrinkle in the ply layers during the moulding process, and wherein the wrinkle control feature cooperates with the stack of ply layers during the moulding process to produce a local surface undulation in a nominal surface of the laminate component nearest the tool to either prevent wrinkling in the ply layers or initiate wrinkling in one or more of the ply layers at a predetermined location. Also, a tool having a wrinkle control feature, and a laminate component so formed. | 05-23-2013 |
20130285292 | MICROWAVE CURING OF COMPOSITE MATERIAL - A method of curing a composite material. A tool is heated using microwaves. At least a part of the composite material is shielded by reflecting microwaves away from the composite material with a shield. Heat is transferred from the tool through the shield to the composite material. The tool comprises a material which is sensitive to microwaves so that, when microwaves are incident upon the tool, some of the microwaves are absorbed by the microwave-sensitive material, thereby heating the tool. | 10-31-2013 |
20140138485 | MODULAR STRUCTURAL ASSEMBLY - A modular structural assembly to form part of an aircraft wing that has an outer skin and a plurality of stringers is disclosed. The assembly includes a plurality of panels, each panel having a portion that forms part of the outer skin and at least one stringer integrally formed with said portion. | 05-22-2014 |
20150069177 | ELECTRICAL POWER TRANSMITTING TELESCOPIC STRUT - A telescopic strut comprises a plurality of hollow members arranged to slide one within another between a retracted and an extended position. Adjacent hollow members are arranged to be electrically connected by one or more electrical connector assemblies as the hollow members move between the retracted and extended positions. Each electrical connector assembly includes an electrically conductive pad on one of the hollow members which is in sliding contact with an electrically conductive strip on the other of the hollow members.
