  • Turbomachine blade with variable chord length
    Patent number: 8221065
    Abstract: A blade of a turbomachine, especially of a steam turbine, is characterized in that the chord length (sm) in the middle region of the blade airfoil is shorter than the chord lengths (s0, S1) in the tip-side region or root-side region of the blade airfoil. As a result of this, a distribution of a Zweifel parameter over the longitudinal extent of the blade airfoil is achieved which minimizes the losses of a blade cascade of the blades.
    Type: Grant

  • Turbo machine blade
    Publication number: 20100284801
    Abstract: A blade (31) of a turbomachine, especially of a steam turbine, is characterized in that the chord length (sm) in the middle region of the blade airfoil (34) is shorter than the chord lengths (s0, s1) in the tip-side region (35) or root-side region (33) of the blade airfoil. As a result of this, a distribution of the Zweifel parameter over the longitudinal extent of the blade airfoil is achieved which minimizes the losses of a blade cascade of the proposed blades.
