Abstract

A cooling fluid air injection system (40) for use in a gas turbine engine (10) includes at an external cooling fluid source (42) , at least one rotor cooling pipe (46), which is used to inject cooling fluid from the source into a rotor chamber (Rc) , a piping system (44) that provides fluid communication between the source and the rotor cooling pipe(s), a blower system (50) for conveying the cooling fluid through the piping system and the rotor cooling pipe(s) into the rotor chamber , and a valve system (48). The valve system is closed during full load engine operation to prevent cooling fluid from the source from passing through the piping system , and open during less than full load engine operation to allow cooling fluid from the source to pass through the piping system.
