Abstract

640,969. Elastic-fluid turbines. POWER JETS (RESEARCH & DEVELOPMENT), Ltd. Feb. 9, 1948, No. 3720. [Class 110(iii)] In a rotor for an axial - flow compressor or turbine in which the blades 3 are secured in axial grooves 2, ring members 6 being arranged in the recesses 5 between adjacent rows of blades and the diameter of the rings being such that when centrally positioned, the peripheries of the rings form a smooth surface with the blade platforms 3a, means are provided whereby the rings may be allowed to take up an eccentric position to permit removal and replacement of blades. This means comprises pins 7 screwed into holes 12 in the rotor, or pins screwed into holes in the rings and having plain portions located in plain holes in the rotor. Cooling ducts 19 may be arranged beneath the blade roots, the rings having skirt portions on either side which extend into the cooling ducts to be swept by the cooling air.
