Abstract : The addition of helium to various gases utilized as working bodies of closed gas turbine installations, allows for a decrease of the value of heat exchange surfaces. The efficiency in this case falls considerably less than with an increase in the temperature pressure heads. (2) The use as working bodies of mixtures of some gases with helium and hydrogen which, in principle will make it possible to create a closed gas turbine installations which will simultaneously have a higher efficiency and a lower value of sizes of heat exchange surfaces than when using pure gases, is advisable.
