Abstract

This paper is devoted to the development of methods for selecting the system characteristics of turbo-compressor units on the basis of the analysis of the test results of the test and pilot models of 6.3 MW turbo-compressor units. On their basis, a new generation of the GPA-Ts-6.3A-type high-performance units was created. Part I of the work presents the state of the problem, as well as objects of research. The requirements for the testing of individual systems with the aim of a thermodynamic analysis of the characteristics of the unit during its operation under the conditions of a closed-loop stand are formulated.

Keywords: turbo-compressor unit, centrifugal compressor, gas turbine engine, polytropic compressor efficiency, effective engine efficiency, integral characteristic of the unit, system characteristic of the unit, exergy approach
