Abstract
801,689. Gas turbine rotors. HENSCHEL & SOHN G.m.b.H. Sept. 12, 1955 [Sept. 10, 1954], No. 26013/55. Class 110 (3). In a cooled gas-turbine rotor, blades 2 are mounted in axially- (or approximately axially-) directed slots 8 formed in the rotor, and small bores 5 are provided in the rotor stubs between the blade-mounting slots, cooling fluid passing from an inner hollow space 6 in the rotor in to the bores to the outer periphery of the rotor. Further small bores 7 are provided and extend from the space 6 towards the bottoms of the blade-mounting slots. The bores 5 and 7 are closed by means of screwed plugs 9. The cooling fluid, which may be water under pressure, may be passed through a heat exchanger where it gives up heat to the fuel. The blades may be secured in the slots by welding, the welded joint assisting flow of heat from the blades to the rotor. Alternatively the blades may be made of ceramic material.
