Abstract: The features of the stages of the design calculation of the parameters for the formation of the initial design of the flow path of the compressor cascade of a twin-shaft engine core of gas turbine engine are presented and described. The article describes recommendations for choosing values of load coefficient, efficiency and other important parameters for stages of medium-pressure and high-pressure cascades at the stage of thermodynamic calculation. At the stage of design gas-dynamic calculation of the compressor at the middle diameter, typical distributions of axial velocity component and reaction rate along the flow path of compressor cascades should be taken into consideration. At the same time, it is necessary to provide requirements for the level of flow braking and static pressure coefficients in the rotor wheels and stator blades, load and Stepanov’s coefficients. The features of the design gas-dynamic calculation of the compressor along the radius of the flow path are a varie ty of flow twist laws at the inlet to the rotor wheels, distributions of the pressure increase and efficiency by the height of the blades. In conclusion, an example of three-dimensional model of compressor flow path formed taking into consideration features of design calculation of parameters of cascade compressors of twin-shaft engine core of gas turbine engine on the basis of the corresponding flow path scheme in the meridional plane is presented.
