Abstract

723,405. Elastic-fluid turbines and compressors. GENERAL MOTORS CORPORATION. Dec. 24, 1952 [Dec. 26, 1951], No. 32692/52. Class 110 (3). In a turbine or compressor rotor wherein each blade has an enlarged root portion mounted in a slot in a support member by a pin which is carried by the rotor and enters an aperture in said root portion, the position and construction of the pin is such that the blade can be released from the slot by sliding it longitudinally thereof thereby causing the pin to shear part of the said root portion. In the compressor shown each rotor disc 14 comprises a thickened rim 30 and a spacing flange 32 the end of which engages a shoulder 36 on another disc 14. The discs 14 are interconnected by dowels 38 and by a tie bolt extending between the hubs of the end discs. The root portion 44 of each blade 16 is located in a dovetailed slot in the rim 30 and is locked therein. by a pin 50 which is frictionally retained within the rim 30. The rim 30 and the pin 50 are made of a material such as alloy steel which is stronger than the material of the root portion 44. The pin 50 bears against a lip 54 on the root which shears during axial displacement of the blade. The stator vanes 12 have tenons mounted in shrouds 18, 20; the shroud 20 comprising concentric channel members 24, 26 having superimposed webs spot welded together.
