Abstract

Description of formation process of two-dimensional scheme of flow path of a two-shaft core engine turbomachinery of aviation gas turbine engine is presented. There were three steps in the design. The first step includes rational distribution of specific work and pressure ratio in the core engine between intermediate and high-pressure compressors, as well as the pressure ratio between high and intermediate-pressure turbines. At the second step we select the rotational speed of the high-pressure cascade and determine the main structural-geometrical cascade parameters in the meridional plane. At the third step the rotation frequency of the intermediate-pressure cascade and the main structural-geometric parameters of the intermediate pressure cascade with a transition duct between compressor compartments are determined. The excess of the middle diameter of the intermediate-pressure compressor over the middle diameter of the high-pressure compressor and introduction of the transition duct between them into the scheme of the compressor flow path of the core engine is justified. Applying of a diagonal turbine in an intermediate-pressure cascade is proposed. The axial length of the flow path channels between compressors and turbines was chosen considering the influence of the duct opening angle on hydraulic losses and mass-dimensional characteristics of the core engine.
