Abstract : The authors make use of the difference methods of A. Ye. Cherkez, 'Applications of the Method of Small Deviations in the Theory of and Calculations for Aviation Turbojet Engines', Oborongiz, 1955, which they apply to the analysis of the working of single- and multi-stage gas turbines in different regimes. The parameters considered in describing the regime are pressure and temperature fore and aft of the turbine stage, consumption of working fluid and rotational speed of the turbine. Universal characteristic curves are presented which show the pressure drops and efficiencies for a two-stage turbine. It is stated that an extension of difference techniques to turbines in supercrutical regimes and in special constructions (such as a birotating turbine) is in progress. (Author)
