Turbine rotor cooling air static collector

United States Patent Application

View the Complete Application at the US Patent & Trademark Office
A gas turbine engine with an air cooled turbine component in which spent cooling air from the turbine component is routed through a rotor disk and into a static vaned diffuser on a static part of the engine so that the spent cooling air can be discharged into the combustor instead of into the turbine hot gas stream. The static vaned diffuser includes de-swirling vanes that de-swirl the flow coming off of the rotor and then diffuses the de-swirled air to increase a pressure for discharge into the combustor.
