  • Patent number: 11952925
    Abstract: A centrifugal degasser of an air-oil mixture of a turbine engine includes a hollow shaft extending along an X axis and a pinion for rotating the hollow shaft, and an annular chamber for centrifugal separation of the mixture. The chamber is arranged around the hollow shaft and forms a fluid passage area, an inlet of which is oriented axially for feeding the chamber with the mixture, and a first outlet of which is oriented radially inwards for the outlet of the de-oiled air separated from said mixture. The chamber also includes at least one second oil outlet oriented radially outwards and configured for discharging the oil separated from said mixture to the outside of the degasser. The chamber and the pinion form a single piece.

  • Patent number: 11938431
    Abstract: A component for a centrifugal deaerator for removing gas from a turbomachine air/oil mixture includes a structural part configured to delimit a duct for the flow of the air/oil mixture, and includes a circumferential enclosure for the centrifugal separation of the air/oil mixture, an axial inlet for the air/oil mixture, radial oil outlets, and an outlet for oil-free air. The component includes at least one cellular structure configured to filter the oil while allowing the air to pass and occupying at least a space in the duct.

  • Patent number: 11401863
    Abstract: The invention relates to a centrifugal deaerator for an air/oil mixture of a turbomachine, comprising: an annular housing (10) for the centrifugal separation of said mixture, arranged around a hollow shaft (11); axial inlets (14) for the flow of said air/oil mixture into said housing (10); a pinion (20) for rotating said housing (10); and radial oil outlets (15) and oil-free air outlets (16), characterised in that it comprises a metal foam (50) housed in said housing (10) by partially extending along the axial direction (XX?) so as to define two successive spaces, a foam-free space (51) and a foam-lined space (52), said foam-free space opening up towards said axial inlets. A device can be advantageously added to the hollow shaft in order to reduce the free-vortex phenomenon and to thereby significantly reduce the load losses of the deaerator.

  • Patent number: 11060456
    Abstract: A centrifugal deaerator for an air/oil mixture of a turbine engine includes: an annular housing arranged around a hollow shaft and having an outer annular wall and an inner annular wall; axial mixture inlets for the inflow of the air/oil mixture into annular housing; a pinion for rotating the annular housing, the pinion including a web that is securely connected to the hollow shaft and to the inner and outer annular walls; radial oil outlets in the outer wall; and oil-free air outlets in the inner wall. The axial mixture inlets and the radial oil outlets are axially arranged on either said of the web to prevent the axial mixture inlets from reintroducing oil evacuated by radial oil outlets into the annular housing.

  • Patent number: 10557767
    Abstract: A torque meter includes a casing and a part is configured to move in the casing in translation in a longitudinal direction under the effect of an axial thrust representative of the torque to be measured. The torque meter further includes a bearing surface connected to the casing via at least one of the ends thereof. The bearing surface extends at least partially in a plane that is substantially perpendicular to the longitudinal direction. One longitudinal end of the movable part is configured to be brought into contact with the bearing surface so that a longitudinal displacement of the movable part leads to a deformation of the bearing surface. The torque meter also has a device configured to measure the deformation of the bearing surface.
