This work deals with test benches features and analysis procedure of operating process efficiency for different systems of turbo-compressor packages of GPA-C type manufactured by Sumy NPO PJSC. The design of back-to-back test rig for full-scale test of centrifugal compressor with high pressure (1,2…12,0 MPa), GTE with power 4,0…25,0 MW and packages as a whole under conditions close to operating conditions at CS of gas and oil industry is presented. The construction diagram and equipment configuration of gas bench of Motor Sich JSC to test turbines D-336 as well as AI-336 on gaseous fuel are considered. The bench permits to perform experimental works not only to run a curve but to research air intake duct geometry effect on pressure field non-uniformity at GTE inlet when being a part of bench. The programs, methodical specifics of full-scale test of gas turbineD-336-1 with power 6,3 MW, centrifugal compressor NCV-6,3/56-1,45 and other systems are described. The analytical dependences to process test results of turbine and gas centrifugal compressor performed under conditions close to operating ones are presented providing the possibility to obtain the package system characteristics based on experimental data as well as verification of this characteristics obtained by calculation at pre-development researches stage.
