Abstract
599,809. Rotors for turbines and compressors. BRISTOL AEROPLANE CO., Ltd., and OWNER, F. M. Jan. 15, 1945, No. 1223. [Classes 110 (i) and 110 (iii)] The rotor of an axial flow turbine or compressor is built up of discs 13 having large central holes. The discs contact at their peripheries and the drum-like centres. They may be secured together by long bolts going through all the discs and the end plates secured to the shaft. Or, they may be secured by long and short bolts 26, 27; the long and short bolts in adjacent lines being in relatively staggered. The bolts may pass through the body of the drum portions or, as shown, through flanges 25. Or, the flanges 25 of adjacent discs may be secured together by short bolts only. Dowel pins may be provided between the bolts or dowel sleeves around the bolts. The turbine or compressor blades have dovetailed roots secured in axial slots and the separating pieces bridge from one disc to the next and form keys. Complete rings may be used instead of individual distance pieces in the axial slots. According to the Provisional Specification, the blades may be formed integral with the discs.
