Abstract— Gas turbines have an important role in electric power generation. Turbine blades are the most important components in a gas turbine power plant. Turbine blades are mainly affected due to static loads. Also the temperature has significant effect on the blades. In this paper the second stage of axial-flow gas turbine rotor blade with holes is created in Solid Works software and design calculation is computed by MATLAB software. The temperature distribution effect on second stage rotor blade with holes is analysed from ANSYS 14.5 software. Three different models with different number of holes (5, 9 and 13) were analyzed to find out the optimum number of holes for good performance.

Gas turbine technology is used in a variety of configurations for electric power generation. The gas turbine in its most common from is a rotary heat engine operating by means of series of processes consisting of air taken from the atmosphere increase of gas temperature by constant pressure combustion of the fuel the whole process being continuous.
A gas turbine is a device designed to convert the heat energy of fuel into useful work such as mechanical shaft power. The gas turbine power plants can be classified into two categories. These are open cycle gas turbine power plant and close cycle gas turbine power plant.
The simple open cycle gas turbine is suitable for industrial gas turbine. The turbine is a rotary mechanical device that extracts energy from a fluid flow and converts into useful work. The gas turbine obtains its power by utilizing the energy of burnt gases and the air which is at high temperature and pressure.
