Abstract

701,154. Turbine and compressor blades. ROLLS-ROYCE, Ltd. May 18, 1951 [March 14, 1950], No. 6432/50. Class 110 (3) An axial flow turbine or compressor blade has a root attachment integral therewith, the root attachment having a channel or groove of " firtree shape tapering towards the blade tip and formed as by broaching, the channel being adapted to engage a correspondingly-shaped axially-extending projection formed at the periphery of the rotor disc so that the root attachment straddles the projection. The blade 12 is hollow and formed in two parts which constitute the concave and convex surfaces of the blade, each part being formed with one limb 13 of the blade root attachment 12b. A channel 11 extends through the projection 11 on the rotor disc through which cooling air passes into the passage 14 extending longitudinally through the blade. The blade may also be formed in one piece with or without a hollow passage therethrough. Specification 611,650 is referred to.
