Abstract

1,089,247. Making aerofoil blades; welding by fusion. ROLLS-ROYCE Ltd. June 3, 1966, No. 24849/66. Headings B3A and B3R. [Also in Division F1] A method of making a hollow aerofoil section blade for a fluid flow machine comprises welding a pair of shaped plates 17, 18 together to form a hollow section blade and welding shaped leading and trailing edge sections 21, 22 to the hollow section. The two plates 17, 18 are made of titanium and are upset to form a local thickness after which they are shaped by hotpressing and chemical machining. The hollow section has ribs 19 and drilledout portions 20 through which tubular spacers (23) are inserted, Fig. 3 (not shown). The spacers (23) may be filled with materials (24) of various density to balance the blade. The leading and trailing pre-shaped edge sections 21, 22 may be hollow or tubular and are electron beam welded to the hollow section. The root section of each blade may be formed by the thickened part (25), (26) of each plate 17, 18 or by a separate shaped root (25), Fig. 4 (not shown), welded to the hollow section.
