Abstract

595,643. Axial-flow compressors. GRIFFITH, A. A. April 23, 1945, No. 10183. [Class 110 (iii)] In an axial-flow compressor or the like in which the radial length of each blade is smaller than its mean radius, the moving blades are supported from a hub of small diameter by thin radial stems, the vibrations of which are damped by means of spring discs mounted on the hub. The inner ends of the blades 15 are provided with shrouding elements 16 which together with spacing rings 23 form a drumlike structure for the rotor. The stems 14 may have projections 17, which may be at different diameters on opposite sides of the stems, upon which the spring discs 18, 18a, 18b exert axial pressure for damping purposes. A number of blades may also be attached to a single stem. Specification 595,642 is referred to.
