Filed: 1994-01-07
Abstract: ABSTRACT OF THE DISCLOSURE A vane for a steam turbine having an improved airfoil that has been stiffened to increase the resistance of the vane to stall flutter without impairing the thermodynamic performance of the vane.  The airfoil is tapered from its tip portion to its hub portion and has a novel shape that includes a higher degree of curvature in its hub region than in the mid-height and tip regions.  This curvature is reflected in the camber angle defined by the leading and trailing edge positions of the airfoil.   In the approximately 40% of the airfoil height adjacent the hub the camber angle is greater than 90° and in the approximately 20% of the airfoil height adjacent the hub, the camber angle is greater than 95°.  In the remainder of the airfoil, the camber exceeds 80°.
