ROTOR WITH COOLING PASSAGE

摘要

A gas turbine engine is disclosed having a cooling passage that rotates with a turbine and is capable of providing cooling flow to the turbine. In one embodiment the cooling passage can receive cooling flow from an interior of a shaft of the gas turbine engine and increase the pressure of the cooling flow before delivering it to a location near a blade of the turbine. In one form the cooling passage can have an inducer section. In one form the cooling passage can have internal vanes useful in increasing the pressure of the cooling flow.
