Gas Turbine Blade Design and Analysis

Turbine blades play a major role in various sectors of the energy production units such as thermal power plants, hydraulic power plants, gas turbine power plants, wind energy power generation plants and in the aviation sector to propel the vehicles, etc. Development of these turbine blades reached to a matured technology level yet the development of turbine blades specifically in the field of gas turbines is at a constant pace. This is because of the complexities faced in the modeling of the blade which will directly interact with the flames from the combustion chamber in which high temperature and pressure exist. Due to this high temperature and pressures in the combustion chamber of the gas turbine and the direct exposure to the flames, the blade faces stress corrosive cracking and reduced life span if we increase the operating conditions such as temperature and pressure. But in order to achieve high efficiency, the turbine should work at supercritical conditions i.e., the temperature of the working fluid should be greater or equal to 6000 C (T≥ 6000 C). This paper aims at modeling a gas turbine blade which works at super-critical operating conditions using the alloys Ti-6Al-4V and the Alloy 1.2367. The results obtained after the simulation process on gas turbine blade with the alloys Ti-6Al-4V and the Alloy 1.2367 are compared and conclusions are stated. The modeling of the gas turbine blade is done in Solidworks Part Design and the simulations and analysis are performed using Solidworks Simulation.
