Abstract

851,400. Making turbine blades. WIGGIN & CO. Ltd., H. Dec. 4, 1957 [Dec. 4, 1956], No. 37049/56. Drawings to Specification. Class 83(2). [Also in- Group XXVI] In a gas turbine blade, the trailing edge of the blade is cooled by a molybdenum insert which lies partly within the trailing edge and partly in an adjacent longitudinal cooling passage inside the blade. The molybdenum has a higher thermal conductivity than the blade and conveys heat to the air flowing in the cooling channel. To prevent oxidation, the molybdenum is coated with electro-deposited nickel. The blade is formed by the extrusion of a billet in which one of the cooling channels is filled with a molybdenum rod and the remaining channels contain a filler which is leached out by acid after extrusion.
