  • Patent number: 5803978
    Abstract: A method of removing blades from the rotor of a turbo machine, such as a steam or gas turbine, in which material deposits formed between the surfaces of the blade root and its retaining groove have effectively bonded the blade root to the rotor groove. The blade root and groove are submersed in a liquid medium enclosed in a tank. Transducers installed on the tank radiate ultrasonic pressure waves into the liquid medium that breakup the material deposits through cavitation, thereby loosing the bond between the blade root and the groove. The blade is then removed from the tank and the blade slid out of the groove.
