    摘要: Vane impingement tubes (34,90) having blockage deterrent features are provided, as turbine nozzles (12) containing blockage-resistant vane impingement tubes. In an embodiment, the turbine nozzle includes inner and outer annular endwalls (24, 26), and turbine nozzle vanes (28) between the annular endwalls. Vane impingement tubes are inserted into the turbine nozzle vanes. The vane impingement tubes each includes a tube body (56, 93), an impingement outlet (40, 40', 92) formed in the tube body and configured to discharge airflow for impingement against the turbine nozzle vanes, a first flow-turning feature (74, 100) located in the tube body, and an inlet (68, 102) formed in the tube body and configured receive cooling airflow in a substantially radial direction. The first flow-turning feature turns the airflow received through the inlet in a substantially axial direction, which is perpendicular to the radial direction, prior to discharge through the impingement outlet.

    摘要: A bearing assembly (110) may comprise a housing (113), a slinger disk (128), and a bearing (115). The housing (113) may be configured to receive a shaft (112) and having at least one scavenge passage (114) between an outer housing portion (118) and an inner housing portion (116). The slinger disk (128) may have a plurality of flow guides (212) configured to direct a lubricant flow (134) toward the at least one scavenge passage (114). The scavenge passage (114) may be configured to provide a lubricant flow (134) through the bearing (115). Lubricant flow (134) may be provided in a forward direction, through the bearing (115) and opposite a windage direction.

    摘要: An inlet particle separator system for a vehicle engine includes a hub section, a shroud section, and a splitter. The hub section has a hub outer surface that diverges, relative to the axis of symmetry, to a hub apex. The shroud section has a shroud inner surface that surrounds, and is spaced apart from, at least a portion of the hub section to define a main flow passageway between the hub outer surface and the shroud inner surface. The splitter is disposed downstream of the air inlet and extends into the main flow passageway to divide the main flow passageway into a scavenge flow path and an engine flow path. The hub section and the shroud section are configured such that the cross sectional flow area of the main flow passageway decreases downstream of the air inlet to define a throat section that is disposed upstream of the hub apex.

    摘要: A turbine disc 202 having a radius and a circumference is provided. The turbine disc includes a central aperture 402 and a plurality of cooling channels 316, 414 circumferentially spaced about the central aperture such that the cooling channels are in flow communication with the central aperture. Each of the cooling channels has a radially inner end 424, a radially outer end 426, and a lengthwise axis 422 that is curved between the radially inner end and the radially outer end.
