description: The theme of the final qualification work: "Methods for the modernization of low-flow stages axial stages with a large relative pitch of rotor blades". In this paper, the influence of the geometric parameters of a low-flow axial turbine stage with a large relative pitch of the rotor blades on the internal efficiency of the unit and the methodology for calcuting sructures of this type by the method of mathematical models: During the study, the following tasks were solved: 1. Three-dimensional models of steps were developed in the NX 3D software package. 2. Three-dimensional calculation models were created using the modern solfware package ANSYS CFX. 3. The calculation of the studied variants of turbine stages was carried out with the determination of the main characteristics using three-dimensional models. 4. Comparison of the final results.In addition to the calculations, the dissertation the main features of the design of low-flow turbines. The undeniable advantages of these installations are revealed, which confirm the relevance of the modernization of this type of turbines. Examples of some studies focused on the study of low-flow turbine stages with a large relative pitch of rotor blades are presented.
