Abstract

726,909. Making turbine blades. OMES, Ltd. Jan. 15, 1953 [Feb. 25, 1952], No. 4919/52. Addition to 569,514. Class 83 (2). A modification of the invention claimed in the parent Specification comprises a method of making a turbine or compressor blade from aerofoil section stock whose cross-section approximates to the section of the finished blade but is narrower and thicker, by upsetting a head on the stock in an electrical upsetting machine, reheating the entire blade and die-pressing both the blade portion 22 and the head 23 to the required form. The die may also impart blade twist and form locating lugs 24, 125 for use in any subsequent machining operations after which the lugs are removed. The blade may finally be electro-polished. Preferably the blade is made of aluminium bronze or stainless steel.
