Abstract

572,859. Turbine and like blades. ARMSTRONG SIDDELEY MOTORS, Ltd., HEPPNER, F. A.- M., and CLAYTON, E. April 3, 1942, No. 4461. [Classes 110 (i) and 110 (iii)] Blades for contra-rotational turbines and air-compressors are held between two conical or other sleeves or shells 17, 18. The shell 18 is formed with oblique slots 24, Fig. 3, into which the shanks 24 of the individual blades fit and the flange which takes the place of the usual root is machined with two cylindrical surfaces 27 which are engaged by the shell 17. For inwardly projecting blades, packing rings 29 are placed under the root flanges. For outwardly projecting blades, both shells make metal-to-metal contact with the flanges. The inner shell may be fixed to the outer shell at one end, provided with a collar bearing on the outer shell at an intermediate region and splined to the outer shell at the other end.
