  • Publication number: 20230017990
    Abstract: A fuel delivery system for a gas turbine engine is disclosed which includes a continuously variable drive assembly having a driving portion operatively associated with a gearbox of the gas turbine and a driven portion operatively associated with a fuel pump of the gas turbine, and a governor for controlling a drive ratio of the drive assembly to vary fuel pump flow performance over a range of engine operating conditions.

  • Patent number: 11199106
    Abstract: A shroud having an annular member extending along an axis from a first end to a second end. The annular member has an inside surface radially inward from an outside surface that diverges from the first end towards the second end relative to the axis. The shroud further includes a flange that extends radially outward from the outside surface and a recess, each located at the second end. The recess extends radially outward from the inside surface and circumferentially about the axis. An axial extent of the recess at least partially coincides with an axial extent of the flange.

  • Patent number: 9303529
    Abstract: A lube spacer bearing for a lube and scavenge pump includes a bearing body defining a bore with a central axis. The bearing body has a first axial side, a second axial side, an outer radial side, and an inner radial side at the bore. The outer radial side includes an arcuate portion. A channel is defined in the arcuate portion of the outer radial side and extends a circumferential length about the outer radial side. The channel has a channel width (CW) defined between a first channel wall and a second channel wall and a bearing length (BL) defined between the first axial side and the second axial side. A ratio of CW/BL is between 0.45 and 0.70.
