Abstract

This article considers the features of creation of the GPA-Ts-type units and their refinement based on the results of field tests of the GPA-Ts-6.3A/56-1.45-type unit as part of a closed-loop stand. It is shown that this allows obtaining the performance characteristics of the main and auxiliary systems, as well as the system characteristics of the unit.

 

Keywords: closed-loop stand, turbo-compressor unit, centrifugal compressor, gas turbine engine, polytropic compressor efficiency, effective engine efficiency
