Abstract
1,268,911. Making turbine blades; brazing. ROLLS-ROYCE Ltd. 26 Sept., 1969, No. 47612/69. Headings B3A and B3R. [Also in Division F1] A method of attaching a hollow blade 10 to a stub member 14 of a root fixing portion comprises inserting the stub member into the blade, securing the stub member to the blade, securing collar portions 20, 22 to the blade and forming a fir tree root fixing 26 on the stub member. The blade 10 is formed by folding a sheet metal laminate to shape, the laminate consisting of three layers, the central of which is formed with shallow channels on either side. Brazing is performed by spraying a stub member projection 16 and subsequently the blade root with a brazing alloy. The blade 10 is a force fit on the projection and the collar portions 20, 22 are clamped to the blade root after it has been sprayed. The assembled blade is placed in a furnace for brazing. The stub member 14 is machined to provide a fir tree fixing 26 having stress relieving radii 28, 30 and the collar is machined to form sealing lands 32 and recesses 34, the latter being preferably formed electrochemically.
