Abstract:
A turbine cooling circuit comprising:a compressor for pressurizing air; a combustor disposed in flow communication with said compressor for mixing fuel with said air to generate combustion gases; a turbine disk disposed downstream from said combustor and joined to said compressor, and including a row of hollow turbine blades extending from a rim thereof; a flow sleeve having an aft end adjoining said disk rim, a first seal rotor spaced forwardly from said aft end, and a row of oval inlet holes disposed forwardly from said first seal rotor, and said sleeve being spaced from said disk to define an annular flowpath extending between said inlet holes and said disk rim for channeling said compressor air to said blades; an inducer having an inlet disposed in flow communication with said compressor, and an outlet disposed radially outwardly from said sleeve inlet holes in flow communication therewith; and a first seal stator sealingly joined to said inducer and surrounding said first seal rotor to define a first rotary seal therewith disposed radially inwardly of said inducer outlet.
