20100254823 | HOLLOW ROTOR BLADE FOR THE TURBINE OF A GAS TURBINE ENGINE - A hollow blade includes an internal cooling passage, an open cavity located at the tip of the blade and bounded by an end wall and a rim and cooling channels that connect the internal cooling passage to the outer face of the pressure wall. The cooling channels are inclined to the pressure wall in such a way that they emerge on the outer face of the pressure wall near the top of the rim. A reinforcement of material is present between the rim and the end wall of the cavity along at least one portion of the pressure wall, whereby the rim is widened at its base adjacent to the end wall in such a way that the cooling channels emerge near the top of the rim without reducing the mechanical strength of the tip of the blade. | 10-07-2010 |

20090304509 | BALANCING SYSTEM FOR TURBOMACHINE ROTOR - The present invention relates to a turbomachine rotor balancing system ( | 12-10-2009 |
20110129336 | ASSEMBLY INCLUDING A TURBINE DISK FOR A GAS TURBINE ENGINE AND A BEARING-SUPPORTING JOURNAL, AND COOLING CIRCUIT FOR THE TURBINE DISK OF SUCH AN ASSEMBLY - The invention relates to an assembly including a turbine disk ( | 06-02-2011 |
20110206504 | FIXED VANE ASSEMBLY FOR A TURBINE ENGINE HAVING A REDUCED WEIGHT, AND TURBINE ENGINE COMPRISING AT LEAST ONE SUCH FIXED VANE ASSEMBLY - A stationary vane assembly for a turbine engine including an inner casing and at least two angular sectors forming a high-pressure guide vane assembly, each angular sector including a fastening tab for fastening the angular sector on the casing. The stationary vane assembly including a ring of abradable material fixed on the casing, on the side of a mobile vane assembly using a plurality of screw-nut assemblies, the stationary vane assembly also including radial retaining pins for the angular sectors introduced into first bores formed in the fastening tabs and in the mounting clip, the bores having axes substantially parallel to the longitudinal axis, the mounting clip being fixed on the casing by the same screw-nut assemblies as those fixing the ring of abradable material support on the casing. | 08-25-2011 |
20120085104 | TURBINE ENGINE INCLUDING AN IMPROVED MEANS FOR ADJUSTING THE FLOW RATE OF A COOLING AIR FLOW SAMPLED AT THE OUTPUT OF A HIGH-PRESSURE COMPRESSOR - A turbine engine including a channel for injecting a cooling air flow of a high-pressure turbine disk, opening into a cavity that is substantially isolated, upstream, from a cavity in which an air flow sampled at the output of a high-pressure compressor circulates, by a first labyrinth seal, and downstream, from a cavity communicating with the primary flow of the turbine engine, by a second labyrinth seal. The turbine engine includes channels communicating with the injection channel and opening through a static part of the first labyrinth seal between two lips of that seal, so as to allow an air flow coming from the injection channel to be injected between the lips. | 04-12-2012 |
20130108434 | METHOD FOR MOUNTING A STATOR BLADING OF A TURBOMACHINE, AN ENGINE CASING AND A TURBOMACHINE COMPRISING AT LEAST ONE STATOR BLADING MOUNTED ON THIS ENGINE CASING | 05-02-2013 |

20160090855 | TURBINE WHEEL FOR A TURBINE ENGINE - A rotating assembly for a turbine engine, comprising a disc having an outer periphery having alternating slots and teeth, blades radially extending from the disc and roots of which are axially engaged in the slots, with spaces called slot cavities being provided between the roots of the blades and the slots, platforms laterally extending from the blades and circumferentially arranged end-to-end, so as to form spaces called inter-blade cavities, and a downstream annular shroud, comprising an outer annular sealing lip opposite the downstream ends of the platforms. The downstream shroud further comprises an intermediate annular sealing lip opposite the downstream faces of the teeth of the disc, radially between the slot cavities and the inter-blade cavities. | 03-31-2016 |

20090048687 | METHOD FOR PLACING A MALLEOLAR IMPLANT FOR PARTIAL OR TOTAL ANKLE PROSTHESIS - A method for implanting a malleolar implant in an ankle joint. A spacer block is positioned between a lower portion of a tibia and an upper portion of an astragalus in the ankle joint. A guide attached to the spacer block is positioned opposite an outer surface of a fibular malleolus. A bore aligned with the guide is formed through the fibular malleolus. The spacer block is removed from between the tibia and the astragalus. A shank of the malleolar implant is engaged with the bore from an inner surface of the fibular malleolus. The shank is advanced into the bore so an inner surface of a head of the malleolar implant engages the inner surface of the fibular malleolus. | 02-19-2009 |
20120191210 | SURGICAL INSTRUMENTATION KIT FOR INSERTING AN ANKLE PROSTHESIS - A surgical instrument including at least one tibial phantom generally corresponding to at least certain features of the tibial implant. The tibial phantom includes a top surface adapted to move freely against the prepared bottom end of the tibia. At least one talus phantom generally corresponding to at least certain features of the talus implant is engaged with the prepared top surface of the talus. At least one phantom skid is located between the tibial phantom and the talus phantom. The phantom skid is engaged with the tibial phantom such that dynamic engagement between the phantom skid and the talus phantom through at least extension and flexion of the ankle joint positions the tibial phantom on the prepared bottom end of the tibia. The phantom skid can either be a part of the tibial phantom or a separate component. | 07-26-2012 |
20130116797 | SURGICAL INSTRUMENTATION ASSEMBLY FOR POSITIONING AN ANKLE PROSTHESIS - In order to position an ankle prosthesis including a tibial implant and a talus implant provided with a talo-calcaneal anchoring keel, the invention proposes a surgical instrumentation assembly including: a tibial phantom ( | 05-09-2013 |
