The results of strength and gas dynamic improvement of turbocharger TK-32 axial turbine are presented. Turbocharger was manufactured by LLC " Penzadieselmash " (Penza, Russian) and is used as unit boost for diesel locomotive. The goal of this work was to ensure turbine work capacity when rotor speed is increased by 10% without efficiency reduction. The(More)
The aim of this article was the development of the gas-dynamic models allowing to calculate the working processes of the gas turbine engine (GTE) in the compressor, in the combustion chamber and in the turbine at the same time. The possibilities of software systems for complex engine workflow modeling are specified. The advantages and disadvantages of the(More)
The research goal was the methodology to calculate gas turbine engine (GTE) workflows and in the compressor, in the combustion chamber and the turbine at the same time. Our method allows predicting interactions between components of a GTE. Solution is provided in separate solvers step by step. The results of modeling entire GTE in a different CFD codes are(More)
