Abstract

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 first portion of cooling fluid cools the leading edge of a turbine blade internally. After first contacting a predetermined area of the component, a portion of that first portion of cooling fluid is then used to film cool the component.
