Turbine blades are considered to be the heart of turbine and play a vital role in extracting energy from high temperature and high pressure gases. Without blades there would be no power and the slightest fault in blading would mean a reduction in efficiency and costly repairs. In this regard, an attempt has been made to analyze the failed marine gas turbine blade. Static structural and Steady state thermal analyses have been analyzed using ANSYS 14.5 to predict the probable conditions which leads blade failure. To investigate the causes of high pressure temperature (HPT) turbine blade failures, a turbine blade of 30 MW gas turbine engine intended for operation onboard ship has been considered for the analysis. Before failure, this gas turbine blade was operated for about 10000 hours while its service life was expected to be around 15000 hours. To improve the life time of a blade, prediction of failure criteria has been analyzed. In addition, a comparative analysis has also been made to determine the strength and suitability of a HPT blade made of Nickel based super alloy X under examination. This material has been compared with other two materials such as Nimonic alloy 80A and Inconel 625. Based on the results of comparative study, it is concluded that Nickel based super alloy X can be a suitable material for the manufacturing of gas turbine blades.
