The modelsused were very detailed high-pressure and low-pressure turbine models with adjoined cavities and a transitionduct consisting of 577 million finite elements. Numerical analysis was conducted both in stationary and nonstationarysetup using BSL and SST models of turbulence. The resulted design data were verified against theturbine test results. Deviations between design and test data, both local and integral, are insignificant (local deviationis not more than 5%). The results of numerical analysis show high level of turbines efficiency. The currentconfiguration was optimized based on the results of verification, which allowed increasing HPT design efficiencyby 0.4%. The model was taken as a basis for a series of works aimed at improving the key parameters of bothindividual turbine components and the module on the whole.</p>High-pressure turbinelow-pressure turbinenumerical studyaerodynamic efficiencyexperimental analysisТурбина высокого давлениятрёхмерное численное моделированиеаэродинамическая эффективностьрасчётно-экспериментальный анализ[1.
