| 20090004000 | DAMPING DEVICE FOR TURBOMACHINE STATOR - The present invention relates to a turbomachine stator forming a stator vane ring or upstream guide vane element comprising a plurality of vanes placed radially between a first inner ring and a second outer ring, the two rings being concentric, the second ring having a cylindrical outer surface portion. The stator is characterized in that, on said outer surface portion, at least one vibration-damping laminate is attached, the laminate comprising at least one layer of viscoelastic material in contact with said surface portion and one counterlayer of rigid material. | 01-01-2009 |
| 20090004021 | MOVABLE IMPELLER FOR A TURBOJET AND TURBOJET COMPRISING SAME - The impeller comprises a blade and a support of said blade which extend substantially radially. It also comprises at least one intermediate part extending, in a substantially axial direction, between said blade and said support of the blade, and at least one damping means placed on at least one face of said intermediate part. The damping means is segmented in an axial and/or circumferential direction into at least two elementary damping means. | 01-01-2009 |
| 20090005183 | DAMPING DEVICE FOR A SHAFT OF A TURBOMACHINE - The present invention relates to a hollow shaft of a turbomachine comprising a cylindrical wall with an inner surface portion and at one end a member for attachment to a rotor disk of the turbomachine. The shaft also comprises a damping device wherein at least one vibration-damping laminate is attached to said inner surface portion, the laminate comprising at least one layer of viscoelastic material in contact with said surface portion and a counterlayer of rigid material. | 01-01-2009 |
| 20090074569 | LEVER FOR ROTATING A TURBOMACHINE VARIABLE-PITCH STATOR VANE ABOUT ITS PIVOT - The present invention relates to a lever for rotating about its pivot a turbomachine variable-pitch stator vane comprising three zones: a first zone for attachment to a lever drive member, a second zone for attachment to said variable-pitch stator vane, and a third zone of elongate shape between the first zone and the second zone, wherein a vibration-damping laminate is applied to at least one surface portion of at least one of said zones of the lever, the laminate comprising at least one layer of viscoelastic material in contact with said surface portion and a backing layer of rigid material. | 03-19-2009 |
| 20090297331 | TURBOMACHINE CASING INCLUDING A DEVICE FOR PREVENTING INSTABILITY DURING CONTACT BETWEEN THE CASING AND THE ROTOR - The invention relates to a cylindrical casing for a turbomachine that is suitable for receiving a rotor fitted with at least one bladed wheel, the casing including a device for preventing instability during contact between the casing and the bladed wheel. In characteristic manner, said device comprises a succession of elements disposed around the circumference of the casing, and presenting between two adjacent elements, different stiffnesses, the number of elements having the same stiffness not being equal to a multiple of the wave number of the vibratory mode of the bladed wheel that is to be inhibited. The invention is applicable to a compressor, a turbine, or a fan. | 12-03-2009 |
| 20110091310 | THERMOMECHANICAL PART CONSTITUTING A BODY OF REVOLUTION ABOUT A LONGITUDINAL AXIS AND INCLUDING AT LEAST ONE ABRADABLE RING FOR A SEALING LABYRINTH - The invention relates to a turbomachine thermomechanical part forming a body of revolution about a longitudinal axis, and including at least one abradable ring for a labyrinth seal. In characteristic manner, the abradable ring is made up of angular sectors that present different stiffnesses between adjacent pairs of sectors. The invention is applicable to a compressor, a turbine, or to a rotor and stator assembly. | 04-21-2011 |
| 20110274540 | TURBOMACHINE CASING - A turbomachine casing forming a continuous annular ring extending over 360° around a bladed wheel and serving as a propagation medium for rotating waves, each rotating wave being generated by two standing waves of the same frequency, and the casing including at least one longitudinal stiffener at its outer periphery that is dimensioned and positioned in such a manner as to separate the frequencies of the two standing waves of at least one given rotating wave. | 11-10-2011 |

| 20110233394 | METHOD OF CALIBRATING AN X-RAY DETECTOR - The general field of the invention includes methods of calibrating X-ray detection systems, the systems including at least one X-ray generator and a detection array having a matrix of detecting semiconductor pixels and processing and calibration electronics. The calibration method includes, for all or some of the pixels: operating the X-ray generator at its nominal high voltage, the generator being placed opposite the detector; counting, using the processing and calibration electronics, the pulses emitted by each pixel through the effect of the radiation produced by the generator; establishing, for each pixel, an amplitude distribution for the counted pulses; applying, to each amplitude distribution, a statistical indicator so as to identify a particular amplitude, this particular amplitude then corresponding to the energy corresponding to said statistical indicator; and adjusting, using the processing and calibration electronics, calibration parameters for each pixel, taking account of the energy-amplitude relationship thus established. | 09-29-2011 |
