Title:
TURBINE MOVING BLADE
Document Type and Number:
Japanese Patent JPH0763004
Kind Code:
A
Abstract:
PURPOSE: To improve reliability of a turbine moving blade by avoiding resonance without sacrificing pneumatic force characteristics.
CONSTITUTION: A stapped portion (a) is formed on an upper side of a T-shaped blade 1 in a turbine rotating direction. The blade root has a width W on its upper side wider than a lower side width W. When oscillation amplitude is enlarged, the stepped portion (a) brings about a contact condition and varies a boundary condition of a turbine moving blade.
