20160001466 | MOLD COMPRISING SHELLS AND AT LEAST ONE SLIDE - A mold comprises a first shell and a second shell that are suitable, in the closed position, for imparting a shape to a part that is to be molded in the mold, a main axis A being perpendicular to the main plane in which the first shell and the second shell extend. The mold further comprises at least one slide that is situated between the first shell and the second shell and that is in contact with the first shell and the second shell when the mold is in the closed position, and that is to come into contact with the molded part, the or each slide presenting a first face that constitutes its interface with the first shell, the first face presenting a primary direction along which the slide is suitable for sliding along the first face when the mold is in the open position. | 01-07-2016 |
20150377282 | IMPROVED METHOD FOR PRODUCING A TRANSMISSION SHAFT, PREFERABLY FOR AN ACCESSORY BOX SYSTEM OF AN AIRCRAFT TURBOMACHINE - A method for producing by pultrusion a hollow main body of a rotary movement transmission shaft made of a composite material, the method including: impregnating a reinforcement; arranging a reinforcing fabric around a pultrusion chuck to wrap the pultrusion chuck, the fabric including circumferential fibers arranged in planes orthogonal to a longitudinal axis of the chuck; and then depositing the impregnated reinforcement around the reinforcing fabric. | 12-31-2015 |
20150354103 | FIBER STRUCTURE FOR AN AXISYMMETRIC COMPONENT MADE OF COMPOSITE MATERIAL WITH A VARYING DIAMETER, AND COMPONENT COMPRISING SAME - A single-piece woven fiber structure for fabricating an axisymmetric part of varying diameter made out of composite material, the fiber structure having a portion of frustoconical shape with a large diameter and a small diameter, the ratio between the large diameter and the small diameter being not less than 2. The fiber structure is formed by winding layers of warp and weft yarns that are woven on a mandrel having a profile that is defined as a function of the profile of the part to be fabricated with warp yarn take-up. For each layer of yarns, the weft yarns are angularly distributed on a single diameter in a zone of the large diameter of the portion of frustoconical shape and on at least two different diameters in a zone of the small diameter of the portion of frustoconical shape in order to form at least two superposed plies of weft yarns. | 12-10-2015 |
20150239553 | FIBER REINFORCEMENT FOR MAKING AN ELONGATE MECHANICAL PART OUT OF COMPOSITE MATERIAL - The invention relates to fiber reinforcement for making an elongate mechanical part ( | 08-27-2015 |
20150104299 | TURBINE ENGINE VANE WITH ASYMMETRICAL PROFILE - The invention relates to a turbine engine vane comprising a main body made of composite material, a leading edge, a trailing edge, and at least one metal structural reinforcement, the structural reinforcement comprising a junction surface portion connected to the main body, the structural reinforcement extending between the junction surface portion and one of the leading or trailing edges, the vane being characterized in that the profile of the junction surface portion of the structural reinforcement has a camber less than 30%. | 04-16-2015 |
20150021455 | TURBINE ENGINE SUPPORT PART OF HYBRID STRUCTURE - A turbine engine support part including a main structure made of composite material and a reinforcing secondary structure made of metal and integrated in the main structure, the secondary structure presenting a geometrical shape and dimensions configured to impart mechanical strength to the support part in event of the main structure being destroyed. | 01-22-2015 |
20150013160 | METHOD FOR PRODUCING A PROPELLER BLADE FROM A COMPOSITE MATERIAL - A propeller blade, which can belong to a fan without covering by an external casing, includes two portions fitted into one another and of different materials, generally composite, to resist various stresses, heating coming from a rotor or impacts of solid bodies. An internal portion includes a blade core, a blade shank and possibly a foam lining, and a preform of an outside portion is assembled to it by surrounding it closely before being completely formed by receiving its resin, which is placed into polymerisation. A method for producing the propeller blade guarantees good assembly of the portions without defects of form, damage or deformation of a fiber weave. | 01-15-2015 |
20130258583 | COMPOSITE MATERIAL FADEC BOX SUPPORT - A device for protecting a computer of an aircraft turbine engine, the device comprising a box containing the computer and a cover covering the box, the box being supported by tabs forming integral portions of the box and maintaining a flow of air between the bottom of the box and a portion of the casing of the engine on which they are to come into secure contact via resilient studs, the box being made of a composite material. | 10-03-2013 |
20130202449 | AXISYMMETRIC PART FOR AN AVIATION TURBINE ENGINE ROTOR - A link part for a turbine engine, in particular such as a turbojet, the link part being mounted between a fan cone and a fan disk supporting fan blades, the link part having an annular wall pierced by a plurality of orifices, each for receiving a fastener member and terminated by a substantially perpendicular rim having an outer surface that provides an aerodynamic extension of the fan between an outer surface of the fan cone and an outer surface of a fan blade platform, the annular wall being made of a first material that is composite and is provided on an inner surface of the rim with a ring made of a second material that is different from the first and that is suitable for radially retaining the fan blade platform. | 08-08-2013 |
20130092071 | HYDRODYNAMIC APPENDAGE SUCH AS A KEEL OR A CENTERBOARD, AND A METHOD OF FABRICATION - A method of fabricating a hydrodynamic appendage for a ship, the method including the steps of: forming two metal half-shells having outside surfaces that form the flanks of a hydrodynamically-active portion of the appendage; forming a metal head including a mechanism for securing the appendage to the ship; and assembling together the half-shells and the head so that the head is sandwiched between the top ends of the two half-shells and closes a top portion of an internal volume defined by the half-shells. The half-shells are welded to the head so as to make the internal volume watertight. | 04-18-2013 |
20130032681 | BRACKET AND METHOD AND TOOLING FOR ITS PRODUCTION - A fitting including at least one composite material bracket with two flat segments forming an angle less than 180° on an inside of the bracket and an angle greater than 180° on an outside of the bracket, together with a stiffener extending on the inside of the bracket between the two flat segments is disclosed. The bracket presents a slot crossing a straight line between the two flat segments, the slot extending into the two flat segments. The stiffener is folded in register with the slot and includes tabs fastened to each of the two flat segments. | 02-07-2013 |
