Abstract

1,100,384. Making turbines and compressors; welding by fusion. BRISTOL SIDDELEY ENGINES Ltd. 22 April, 1966 [10 March, 1965], No. 10274/65. Headings B3A and B3R. [Also in Division F1] The titanium stator assembly of an axial flow turbine or compressor is constructed by forming blade mounting slots in an inner wall 1 and then welding outer walls 2 and 3 to wall 1 at 5, 6, 7 and 8. The root portions of the blades 9 are inserted through the slots in wall 1 and caused to form slots in walls 2 and 3 by stabbing. The blades are then secured in position by circumferentially extending lines of electron beam welding 10. Each blade root may be sharpened to an arrow head to assist the stabbing, in which case the sharp portion is ground away prior to welding.
