A method of calculation of cooled gas turbine parameters is proposed. The method is based on the solution of the expansion process equation, heat transfer equations for cooled elements and on the results of the statistic processing of the parameters.

The method is valid for the turbine with any cooling system and gaseous heat carrier. Turbine output determination error does not exceed 0,5–1,0%.

The method allows to obtain the characteristics of gas turbines and gas turbine units (GTU) with open and closed air and steam cooling systems and to carry out an efficiency analysis of their performance in power generating units of various structure.
