| Abstract: | Almost all commercial electrical power on earth is generated with a turbine, driven either by wind, water, steam or burning gas. Around 22% of total global power generation is produced by gas power plants. Turbine Blades of a turbine engine are very prone to damage from flying debris; moreover they also sustain thermal stresses and local overheating on their surface of gases that are coming out from combustion chambers. Due to increase in generating capacity and operating pressure of individual utility units, various new methods have been employed to increase the efficiency of turbines. Recent methods include thin and highly twisted design of turbine blades with low aspect ratio, which results in high levels of vibratory stresses and forces the designers to use higher strength materials. Turbine blades are subjected to very strenuous environments inside a gas turbine. They face high temperatures, high stresses, and a potentially high vibration environment. All these factors can lead to blade failure, resulting in catastrophic failure of turbine. In this research work, root causes of failures of high pressure gas turbine blade have been illustrated in detail. |
