An Experimental Study on Evaluation of Gas Turbine Blade Integrity

가스터빈 블레이드의 건전성 평가를 위한 실험적 연구

An experimental method is devised to identify the vibration characteristics of G/T blade in power plants. The acceptance margin to avoid resonance due to nozzle waking force is established and evaluated by suggested method. It is expected that improvement of turbine availability and the localization of blade can be achieved by using the result of this study.
