초록

An air-to-air heat exchanger is provided for a gas turbofan engine to significantly reduce the quantity of cooling air that is presently needed to effectively cool the hot turbine parts. Typically, the turbine is internally cooled with air bled from the compressor which, though cooler than the turbine, has been heated due to the work done on it by the compressor. In accordance with the present invention, the heat exchanger is located internally of the bypass duct to place in heat exchange relationship a captured portion of the relatively cool bypass flow...

청구항

In a gas turbine engine of the bypass variety having a fan for pressurizing a cool flow of fan bypass air; a core engine including a compressor for pressurizing a hot flow of cooling air; a turbine of the air cooled variety; a heat exchanger for receiving a portion of the cool bypass air and a portion of the hot cooling air, wherein heat is transferred directly from the hot cooling air portion to the bypass air portion thereby resulting in a flow of cooled cooling air; and a means for routing the cooled cooling air to the turbine for turbine cooling; an ...
