description: This work is devoted to the design of a dual-circuit turbojet engine with a capacity of 78 kN, designed for medium-haul passenger traffic. Tasks that weresolved in the course of the final qualification work of the: 1. Carry out a thermodynamic calculation of the engine, select the optimal values T_3^* and Ï_k^*. 2. Makegas-dynamic calculation of the axial compressor of the transport type. 3. To calculate the main parameters of the direct-flow annular combustion chamber. 4. Perform gas-dynamic calculation of the turbine, which is the compressor drive. 5. Profiling the blades of the last stage of the turbine. 6. Calculate the strength of the working blades and the disk of the last stage of the turbine. 7. To carry out a feasibility study on the choice of cooling system for the working blades of the first stage of a high pressure turbine. As a result, a turbofan engine with a large bypass ratio based on the Sam -146 engine was designed. The engine designed meets all the requirements, and is highly economical. In terms of its performance, the engine is comparable to foreign engines in thispower class, and therefore is competitive in the market.
