Abstract

844,068. Making turbine and like blades. WIGGIN & CO. Ltd., H. May 23, 1958 [June 7, 1957], No. 18195/57. Class 83 (2). [Also in Group XXVI] A turbine or compressor blade comprises longitudinal cooling passages arranged in pairs, the two passages of each pair merging into one another close to the tip of the blade. The blade may be made by partial extrusion of a billet 1, Fig. 1, in which the holes have been drilled and filled with a filler which flows with the metal of the billet during the extrusion, and is then subsequently leached out by acid. In Fig. 6, the cooling passages consist of holes 4, 5 merging into each other close to the tip and holes 6, 7 meeting each other in the root of the blade thus forming a diamond pattern. At one or both edges of the blade are one or more single holes 2, Fig. 1. A modification, Fig. 11, has a slot 11 which is formed by machining (e.g. spark erosion) the single row of passages at the blade tip.
