Abstract

857,292. Making turbine or compressor blades; extruding. WIGGIN & CO. Ltd., H. May 20, 1958 [May 22, 1957], No. 16413/57. Addition to 830,472. Classes 83 (2) and 83 (4). A turbine or compressor blade with longitudinal cooling passage is made by drilling a billet from opposite ends to provide larger holes at one end and smaller intersecting holes at the other end, the holes lying on a common plane, filling the holes with a removable filler, partially extruding the billet through a die whereby the extruded portion 5 has the desired cross-sectional area of the blade proper and the larger holes therein lie substantially in a straight line, Fig. 8, and thereafter shaping the blade to the desired aerofoil shape with the holes lying on a curve. The latter is done by forging. The extruded blank may be tapered longitudinally by machining or gap rolling before forging. Specifications 827,289 and 840,665 are referred to.
