METHODS, SYSTEMS AND/OR APPARATUS RELATING TO FREQUENCY-TUNED TURBINE BLADES

摘要

PURPOSE: A tuning method of a compressor stator blade is provided to change the natural frequency of an airfoil of a turbine blade without changing the shape of an air foil or the design of a root. CONSTITUTION: A tuning method of a compressor stator blade comprises following steps. The natural frequency of the compressor stator blade(155) is distinguished. The target natural frequency of the compressor stator blade is determined. Material is removed by the structure constituting target natural frequency from one among side surfaces of a base portion of the compressor stator blade.
