The need to identify the main controlled parameters (characteristics) of the engine, determined in experimental studies, which depend on a large number of parameters, uncontrolled during the experiment has caused the need to apply software identification tools that allow to reduce the complexity of these works.
The paper presents the results of GT D045 mathematical model adaptation to the Optimum software system for optimization and identification of parameters and characteristics of power plants, developed in IPMash NAS of Ukraine, allowing to calculate the identification criteria, parameters and characteristics of the studied object using the same equations as in the design. The choice of variable and controlled parameters, as well as the range of their changes is described. The principles of further improvement of the methodology for setting the ranges of change of variable and controlled parameters, based on direct measurements of the material part and the experience of the researcher-developer are given.
The results of solving a test identification problem demonstrate the possibility and feasibility of using the Optimum system for the identification of the mathematical model of GT D045 during its fine-tuning.
