description: The purpose of this graduate qualification work is to improve the efficiency of the system âturbine last stage - outlet diffuserâ by modifying its design. The tasks performed in this paper are: 1. Construction and optimization of the mesh model of the system âStage - Diffuserâ of the has turbine unit in ICEM and Turbogrid programs. 2. Analysis of the results of numerical simulation of the flow of the system âstage - diffuserâ obtained in the program ANSYS CFX. 3. Optimization of the design of the system âstage - diffuserâ on the basis of calculation results. The relevance of this work is due to the fact that at the moment LADOGA 32 is the main gas turbine engine of medium power in the domestic market. In the graduate qualification work the geometry of the support rack and longitudinal section of the diffuser of the gas turbine unit were changed, which resulted in the increase of pressure recovery coefficient in the diffuser. Also the replacement of the twist law of the last stage of GTU was recommended.
