Abstract

1,222,926. Rotor blade fixing. UNITED AIRCRAFT CORP. June 26, 1969 [July 25, 1968], No.32260/69. Heading F1T. Turbine or compressor blades 12 are locked in axial slots 14 in the periphery of a rotor disc 10 by engagement of tabs 22, 24 at one end of the root 20 of each blade with one face 16 of the disc and by a locking plate 32 located within a circumferential groove 26 at the other end of the root 20 and engaging the other face 18 of the disc. The plate 32 is retained radially by a member 40 having bent up ends 42, 48 and a portion 46 extending axially beneath the root 20. Tabs 34, 36 on the plate 32 prevent the latter moving circumferentially. (For Figures see next page)
