Cooling air delivery systems for gas turbine engines are used to increase component life and increase power and efficiencies. The present system increases the component life and increases efficiencies by better utilizing the cooling air bled from the compressor section of the gas turbine engine. For example, a flow of cooling air which is directed through internal passages of the engine and into a cavity and is used to cool the interface between a turbine disc and a plurality of turbine blades and further reduces ingestion of hot power gases into the internal portion of the gas turbine engine. The cavity has a generally tapered configuration and effectively cools the interface between the disc and the blade. Thus, increasing component life and increasing power and efficiencies of the engine.
A cooling air delivery system for cooling components of a gas turbine engine having a turbine assembly, a compressor section and a compressor discharge plenum fluidly connecting the air delivery system to the compressor section comprising:
A turbine assembly including a disc having a first side, a second side, an outer periphery having a plurality of slots therein extending axially between the first side and the second side, and a plurality of blades having a root portion positioned in corresponding ones of the plurality of slots;
