Abstract: A sump pressurization system for a gas turbine engine comprises a first hollow shaft and a second hollow shaft disposed within the first hollow shaft and defining a cavity therebetween. Each of the first and second hollow shafts has a common axis of rotation. Also included is a source of pressurized air to pressurize the cavity and a plurality of hollow tubes disposed in the cavity. The tubes are oriented perpendicular to the axis of rotation and are connected to and rotatable with the first hollow shaft. A plurality of apertures in the second hollow shaft are in fluid communication with the tubes, such that pressurized air flowing through the tubes passes through the apertures into the interior of the second hollow shaft.

Abstract: An apparatus and system for injecting fluid into a boundary layer of a flow of fluid are provided. The boundary layer injection insert assembly includes an insert body and a central bore extending through the insert body from an inlet opening positioned at a first end to an outlet opening positioned at a second end of the insert body opposite the first end. The insert body is approximately cylindrical about a longitudinal axis and includes a thickness in a radial direction orthogonal to the longitudinal axis. The first end includes a plurality of injection holes extending through the thickness for a first distance, the first distance being less than the length. The boundary layer injection insert assembly also includes an annular spacer at least partially surrounding the second end and including a radially inner surface and a radially outer surface spaced apart by a thickness of the annular spacer.
