Turbine cooling circuit

摘要

A turbine cooling circuit (32) includes a flow sleeve (34) having an aft end (36) for adjoining the rim (30a) of a turbine disk (30). A seal rotor (38, 42) is spaced from the aft end adjacent a row of inlet holes (40). An inducer (46) has an outlet (50) disposed radially outwardly from the sleeve inlet holes. And, a seal stator (52,54) surrounds the seal rotor to define a rotary seal disposed radially inwardly from the inducer outlet.
