Abstract

635,890. Turbine rotors. POWER JETS (RESEARCH & DEVELOPMENT), Ltd., and GRANTHAM, C. Nov. 28, 1947, No: 25538/49. Divided out of 631,152. [Class 110(iii)] A turbine rotor is built up of disc laminae. The discs 2 are assembled on a sleeve 3 and clamped by a nut 28. The assembly is clamped between plates 6, 13 by bolts 7 having a tight fit in holes in the discs. Cooling air from a fan 22 passes through holes 21 to spaces 20 separated by radial ribs and thence to channels below the blade roots and the blade platforms. Specifications 628,036, 631,152 and 631,163 are referred to.
