Abstract

1450133 Cooling gas turbine engines MASCHINENFABRIK AUGSBURG-NURNBERG AG 17 Dec 1973 [21 Dec 1972] 58301/73 Heading F1G Cooling of gas turbine rotor blades 4 is effected by coolant air, e.g. from the compressor stage or from a compressed air reservoir, directed on to the rotor disc 3 at its junction with the blade roots by nozzles 13 from an air chamber 14 in the stator 5 and directed on to the blade tips by nozzles 9 formed as radially directed circumferential slots surrounding the blade tips and connected to an air chamber 7. The air from nozzles 13 may alternatively be directed immediately on to the blades.
