Abstract
Heavy turbofan engines with high thrust values have a special place among air engines. Between the components of gas turbine engines, the turbine part is very sensitive and important due to the high temperature and long-distance operation of its components. In the present study, based on the results of the cycle design, the conceptual design of the turbine of the considered turbofan engine has been done by using the defined software and algorithms. The pressure ratio of the designed turbines in the conceptual design and numerical simulation section differed only by 0.7 and 0.5%. However, the efficiency of the high pressure turbine differed by about 5.6% between the conceptual design and the numerical simulation due to not considering the cooling in the numerical simulation.
