Abstract
702,521. Turbine rotors. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. July 6, 1950 [Aug. 10, 1949], No. 20849/49. Class 110(3) In a bladed rotor for an axial-flow turbine or similarly bladed fluid flow machine comprising a number of laminar discs 1, radially-extending fingers 2 are formed around the peripheries of at least some of the discs so as to afford in combination a series of evenly-spaced projections around the periphery of the rotor on which hollow blades 3, 4 are mounted. The fingers on the successive. laminae are shaped to correspond with the shape of the hollow interior of the blades. The blades are formed in two parts formed with shroud portions 3a, 4a which extend around the periphery of the rotor, and with radially-inwardly extending portions, the parts being connected by welding, and the blades being secured to the projections by welding adjacent the tops thereof. The end laminae have no projections so as to afford a passage for cooling air which enters through the notch 5 in the end laminae. The laminae may be spaced apart so as to formpassages for cooling air from an inner portion of the rotor. Specifications 702,739 and 702,740 are referred to.
