Abstract

1410607 Turbomachine rotors GENERAL ELECTRIC CO 24 Nov 1972 [2 Dec 1971] 54331/72 Heading FIT Vibrations of the blades 14 on a turbomachine rotor 12 are damped by assemblies 24 each disposed in the gap between a pair of adjacent blade shanks 19 and comprising dovetails 32 locked radially by engagement with shank recesses 36, U-shaped damper weights 44 movably mounted on a bridge member 30 so as to be urged centrifugally into engagement with the undersides of blade platforms 18 and end-plates 26, 28 to prevent leakage flow through the shank gaps.
