Moscow Power Engineering Institute (Technical University), Moscow, Russia aut Analysis of physical processes and operating behavior of gas turbine units with high loading of the gas turbine stage [Elektronische Daten] [A. Granovskiy] Aspects of using a highly loaded stage in place of a group of stages in gas turbines are analyzed. Experimental data for individual wheels, as well as for the entire stage as a whole, are presented which confirm the possibility of obtaining efficiencies relative to braking of 0.87 - 0.89 during operation of the stage with turbine load parameters of 0.40 - 0.48. This makes it possible to reduce the number of stages without significant loss of gas dynamic efficiency. The cooling air feed rate is lowered and fewer parts are needed, thereby reducing the cost of the entire turbine.
