Revalorisation of the Szewalski’s concept of the law of varying the last-stage blade retraction in a gas-steam turbine

The article presents the implementations of the free vortex law to the blade of the last stage of a gas-steam turbine. First, a thermodynamic analysis was carried out, determining the parameters at the inlet, then the number of stages of the high and low-pressure part of the turbine was constructed,...
