  • Turbomachine turbines with blade inserts having resonant frequencies that are adjusted to be different, and a method of adjusting the resonant frequency of a turbine blade insert
    Patent number: 7037078
    Abstract: In a moving turbine wheel, blade inserts are used with at least two blades interconnected by common outer and inner platforms and sharing a common root. The blade inserts have hollow roots in which respective recesses are formed, and the insert roots belonging to the same wheel and/or two different wheels are voluntarily given different configurations in order to adjust the resonant frequencies of the inserts to values that are significantly different, thereby ensuring that the inserts in the same wheel and/or between two different wheels are out of tune.
    Type: Grant

  • Making turbomachine turbines having blade inserts with resonant frequencies that are adjusted to be different, and a method of adjusting the resonant frequency of a turbine blade insert
    Publication number: 20040219024
    Abstract: For the or each moving wheel of the turbine, blade inserts are used each comprising at least two blades interconnected by common outer and inner platforms and sharing a common root. Inserts are used having hollow roots in which respective recesses are formed, and the roots of inserts belonging to the same wheel and/or the roots of inserts belonging to two different wheels are voluntarily given different configurations in the inserts of the roots so as to adjust the resonant frequencies of said inserts to values that are significantly different, thereby ensuring that the inserts in the same wheel and/or between two different wheels are out of tune. The invention is applicable to turbines both for aviation and for industrial applications.
