Abstract

1,005,140. Turbine and compressor blades. STAL-LAVAL TURBIN A.B. Oct. 3, 1963 [Oct. 18, 1962], No. 38890/63. Heading F1T. [Also in Division B3] A radial flow turbine or compressor blade has an attachment foot formation 2 at each end, each formation having machined attachment profiles 3 to fit into grooves in supporting rings holding the blades together, the blade consisting of two parts, a main part 1 from which the attachment profiles 3 are machined and a cast inlet edge part 4 of a material harder than the main part 1, the edge part 4 extending along the entire length of the blade and having portions 5 at its ends forming part of the attachment foot formations 2, the parts 1, 4 being joined together by brazing or welding. The contraction reduces blade erosion, particularly in steam turbines.
