Abstract

609,446. Turbine blades. PARSONS & CO., Ltd., C. A., and GARDNER, F. W. March 14, 1946, No. 7998. [Class 110 (iii)] Each blade is secured between teeth which lie parallel or substantially parallel to the axis of the rotor, and either or both the blade roots and the rotor teeth are bifurcated. The blade roots f and the rotor teeth e are bifurcated by means of slits c, terminating in circular holes d to avoid stress concentration. Further slits may be provided in the rotor between the teeth.
