Optimal design of the high-pressure cylinder flow path in updating the T-100-12.8 steam turbine

The discussion concerns some alternatives of updating the high-pressure cylinder (HPC) flow path of the T-100-12.8 turbine using an optimal design method that made it possible to find and realize means of enhancing the turbine efficiency. The effectiveness of using the advanced design solutions affording a high efficiency value of the HPC is demonstrated.
