Title:
ターボ機械用翼
Document Type and Number:
Japanese Patent JP5420729
Kind Code:
B2
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.
