In order to obtain better life and good thermal performance of the blade tip, it is necessary to increase the aerodynamic efficiency of the blade. Even though process of cooling is efficient with existing methods it is mandatory to improve the blade design to decrease the pressure drop without affecting the overall efficiency. This paper intends to improve the turbine blade life and also to reduce maintenance cost by designing and analysing various blade tip configurations. They thermal
