description: The purpose of this work is to study the influence of tangential slope of the guide blades on the characteristics, flow structure and reactivity gradient of the axial turbine stage, and to create an optimal (within the framework of the research) turbine stage with tangential slope of the guide blades. In this paper, a 2D design calculation of the stage is performed using the following methods: the flow twist according to the law of potential vortex and the law of constancy of the angle Î±1 at Î´=0 in the software package OPTOX.EXE. Further, if the angle Î±1 is constant, the stage calculations are performed for different values of the tangential angle of the guide blades Î´=4, 8, 12, 16 degrees in the software package OPTOX.EXE. After analyzing the results obtained, computer optimization of the stage was performed, and appropriate conclusions were made. Based on the results of calculations, the stage guide blades with a variable tangential slope (at the root of Î´Ë=8, at the periphery of Î´ËË=0) were profiled in the Siemens NX program. For the resulting model, a 3D gas dynamic verification calculation was performed in the ANSYS CFX program. The characteristics of the stage and the flow structure are determined. Conclusions are made about the feasibility of using variable tangential slope of the guide blades in the axial turbine stage.
