The need to identify the main controlled parameters (characteristics) of engine, determined in experimental studies, which depend on a large numbers 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 result of GT D045 mathematical model adaption to the Optimum software system for optimization and adaptation 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 equation as in design. The choice of variable and controlled parameters, as well as range of there changes is described. The principles of further improvement of 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 using the Optimum system for identification of the mathematical model of GT D045 during its lapping.
