Abstract

939,505. Turbine blades. ROLLS-ROYCE Ltd. April 24, 1962, No. 15636/62. Class 110 (3). A blade suitable for use in a hot fluid stream has a leading edge 16 of ceramic material and metal trailing surfaces. In a gas turbine nozzle guide vane the trailing surfaces comprise a hollow metal part 17 and ribs 26 on the leading edge 16 are in contact with the part 17 to maintain a space allowing for differential expansion therebetween. Cooling air from the compressor enters the radially outermost portion of the blades from a manifold 29 and passes into the working fluid stream through slots formed between the leading edge 16 and the part 17. The leading edge 16 is made of silicon nitride and the blade ends fit into axial slots 21, 22 in flanges 23, 24 of the inner and outer concentric walls 11, 12 of the main turbine duct. The part 17 is welded into the slots and a flanged abutment is provided at the upstream end of the slots to position the leading edge 16. A metal tube may be mounted, either slidably or fixedly, longitudinally of the leading edge 16.
