Abstract: A manifold for use in a clearance control system is provided. The clearance control system includes a housing including a plurality of walls that at least partially define an interior of the housing, and a nozzle portion integrally formed with the housing. The nozzle portion extends between adjacent walls of the plurality of walls and including at least one nozzle projection having a plurality of impingement openings defined therethrough. The at least one nozzle projection extends from the adjacent walls in an outward direction relative to the interior of the housing.

Abstract: Splitter apparatus for gas turbine engines are disclosed. An example splitter apparatus may include a splitter including an annular outer wall substantially defining a convex leading edge; an annular splitter support positioned radially within the outer and including a forward end disposed substantially against a splitter inner; and an annular first bulkhead spanning between the outer wall and the splitter support. The outer wall, the splitter support, and the first bulkhead may define a generally annular splitter plenum. The forward end of the splitter support may include spaced apart, radially oriented metering slots. The outer wall may include an inner portion disposed radially inward from the splitter inner surface extending aft and including spaced-apart exit slots. The splitter plenum, the metering slots, and the exit slots may conduct airflow from the plenum, through the metering slots against the splitter inner surface, and through the exit slots.

Abstract: A method of controlling a clearance gap in a rotatable machine and a cooling fluid distribution system are provided. The cooling fluid distribution system includes a component to be cooled having a body extending along a longitudinal centerline of the component and including a radially outer surface at least partially circumscribing the longitudinal centerline. A cooling fluid distribution duct assembly includes a cooling fluid distribution duct extending along and spaced from the radially outer surface for a predetermined length. An outlet hole extends through the cooling fluid distribution duct along a length of the cooling fluid distribution duct. A cooling runner channel is coupled in flow communication with the cooling fluid outlet hole and extends a distance away from the cooling fluid distribution duct toward the radially outer surface. A distal end of the cooling runner channel includes a plurality of cooling holes directed toward the radially outer surface.
