Abstract

872,041. Making blanks for turbine blades. SOC. NATIONALE D'ETUDES ET DE CONSTRUCTION DE MOTEURS D'AVIATION. July 16, 1957 [July 31, 1956], No. 22494/57. Class 83 (2). A metal blank 6, Fig. 5, of varying thickness, for subsequent conversion into a turbine or compressor blade, is made by stamping a flat metal strip 1, Fig. 2, to provide the desired hollow profile 3 on one face and a protruding portion 2 on the opposite face, and then removing the protruding portion. The starting strip 1 is preferably formed by the method described in Specification 872,040. After stamping a number of blanks in the strip the protruding portions 2 are removed by planing, milling or grinding and the blanks 6, Fig. 5, are then severed from the strip 1. Finally these blanks are folded into turbine or compressor blades so that the thick edges 8 abut and these are welded together to form the trailing edges of the blades.
