A gas turbine engine having a compressor and an air-cooled turbine is provided with a cooling system for decreasing the temperature of the turbine cooling air. A compact heat exchanger, rotatable with the compressor, receives a portion of the pressurized air which is bled from the compressor. Relatively cool engine lubrication oil is pumped through the heat exchanger into heat exchange relationship with the pressurized air, thereby cooling the air and heating the lubrication oil. The cooled air is then routed to and circulated through the turbine blades ...
A gas turbine engine comprising a compressor for pressurizing air, a turbine having blades of the air-cooled variety, an engine lubrication system, and a heat exchanger rotatable with said compressor and having a first inlet in fluid communication with said compressor for receiving pressurized air therefrom, a second inlet in fluid communication with said lubrication system for receiving lubricant therefrom and an outlet for said pressurized air in fluid communication with said turbine blades.
