Title: Compressor ported shroud for foil bearing cooling

Abstract

A compressor ported shroud takes compressed air from the shroud of the compressor before it is completely compressed and delivers it to foil bearings. The compressed air has a lower pressure and temperature than compressed outlet air. The lower temperature of the air means that less air needs to be bled off from the compressor to cool the foil bearings. This increases the overall system efficiency due to the reduced mass flow requirements of the lower temperature air. By taking the air at a lower pressure, less work is lost compressing the bearing cooling air.

  • A turbine shroud cooling cavity is partitioned to define a plurality of cooling chambers for sequentially receiving cooling steam and impingement cooling of the radially inner wall of the shoud. An impingement baffle is provided in each cooling chamber for receiving the cooling media from a cooling media inlet in the case of the first chamber or from the immediately upstream chamber in the case of the second through fourth chambers and includes a plurality of impingement holes for effecting the impingement cooling of the shroud inner wall.
  • This patent describes an easily removable cooling fan shroud adapted to be mounted between an engine and a radiator of an engine vehicle, comprising a rigid engine mounting, a rigid radiator mounting, and a flexible member formed as a circular cylindrical bellows normally extending between and connecting the engine mounting and the radiator mounting; wherein the bellows is spaced and separated from free ends of blades of a cooling fan, and the bellows extends from the radiator mounting to substantially a plane of rotation of the cooling fan and the bellows is axially compressible for removal of the cooling fanmore » shroud through a space between the radiator and the cooling fan, lower portions of the engine mounting and the radiator mounting being engageable by slidably releasable U-shaped hook means with supports projecting from the engine and the radiator, upper portions of the engine mounting and the radiator being secureable to the engine and the radiator by means of bolts.« less
  • An open cooling circuit for a gas turbine bucket wherein the bucket has an airfoil portion, and a tip shroud, the cooling circuit including a plurality of radial cooling holes extending through the airfoil portion and communicating with an enlarged internal area within the tip shroud before exiting the tip shroud such that a cooling medium used to cool the airfoil portion is subsequently used to cool the tip shroud.
  • An open cooling circuit for a gas turbine airfoil and associated tip shroud includes a first group of cooling holes internal to the airfoil and extending in a radially outward direction generally along a leading edge of the airfoil; a second group of cooling holes internal to the airfoil and extending in a radially outward direction generally along a trailing edge of the airfoil. A common plenum is formed in the tip shroud in direct communication with the first and second group of cooling holes, but a second plenum may be provided for the second group of radial holes. Amore » plurality of exhaust holes extends from the plenum(s), through the tip shroud and opening along a peripheral edge of the tip shroud.« less
  • This patent describes turbine engine having a rotatable turbine assembly, a generally cylindrical shroud disposed concentrically around at least a portion of the turbine assembly and a sealing ring disposed generally concentrically around the shroud. The shroud is provided with at least one cooling air passage extending therethrough and at least one cooling air inlet extending into the at least one cooling air passage. The sealing ring and the shroud are axially movable with respect to each other. At least one cooling air inlet is dimensioned and positioned with respect to the sealing ring such that under at least certainmore » operating conditions of the engine the sealing ring moves relative to the shroud to block the at least one cooling air inlet.« less
