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.
