The analyses of geometry influence of centrifugal compressor rotor bundle at specified characteristic of gas turbine engine of turbo-compressor of gas industry is made.  It is established that at geometrical angles of impeller vanes shape less than 32î it is provided  coincidence of design condition of compressor operation and optimum condition of package operation  determined by characteristics of turbine and compressor. The requirements to integral characteristic of “compressor-turbine” system providing developing optimum operating conditions of package are stated.

Key words: compressor, gas turbine, package, efficiency, operating condition.
