Abstract

PURPOSE: To improve turbine efficiency, by increasing the tooth number of the nose part of a movable vane, and by further setting a step-like form, which prevents the damage of fins by the difference of elongation between a turbine casing and a rotor, to the auter race part of a stator blade ro the inner surface of the casing.
