description: Theme of the final qualifying work: Â« Turbofan bypass aircraft gas turbine engine with thrust of 125 kN Â». The purpose of the presented work is to calculate and design a 125 kN thrust bypass engine based on the PS-90A prototype. To fulfill the established tasks, the following actions were carried out: 1) A variant calculation of the cycle parameters was carried out with the choice of the most optimal degree of pressure and temperature increase. 2) An approximate calculation of an axial compressor, including a fan, a low pressure compressor and a high pressure compressor. 3) Gas-dynamic calculation of the turbine. 4) Calculation of the last stage of the low-pressure turbine for strength. 5) A brief description of the main components of the engine. As a result of the work done, we achieved the required parameters, while maintaining high rates of all important engine characteristics. A special part is the development of a software system for designing air intakes.
