Multiloop control system study of a gas turbine compressor and power unit: II - Experimental investigation

This paper describes the experimental evaluation of the dynamic characteristics of an air-borne multipurpose gas turbine engine and its control components. Justification of the test technique is given and the test procedure and type of instrumentation used in the evaluation is discussed, as are the methods of generating the driving functions for the test. The results of the evaluation are presented and the correlation of these results with the analytical results1 is presented.
