Background
Turbine blades are important components of the turbine section of a gas turbine engine. The blades rotating at high speed are responsible for drawing high-temperature and high-pressure airflow into the combustor to maintain the operation of the engine. In order to ensure stable and long-term operation in extreme environments of high temperature and high pressure, turbine blades are often forged from high temperature alloys and are cooled in different ways, such as internal air flow cooling, boundary layer cooling, or thermal barrier coatings protecting the blades, to ensure operational reliability. In steam turbine engines and gas turbine engines, metal fatigue of the blades is the leading cause of engine failure. Strong vibration or resonance can lead to metal fatigue. Engineers often use friction dampers to reduce the damage these factors cause to the blades.
