Abstract. The authors constructed a mathematical model for changing the parameters of an aircraft engine for use in the ECTM (Engine Condition Trend Monitoring) system, which will allow for the maintenance of foreign-made aircraft under sanction restrictions based on the airline data.
The mathematical model was constructed with the regression analysis method on the basis of statistical data of PT6A-114A engines technical operation over a five-year operation period. The proposed solution allows the values of the basic parameters of the PT6A-114A aircraft engine to be obtained, the operator having the opportunity to independently analyze the trends of changes in the engine condition without the ESTM system. The main advantage of the obtained research results is independence of the aircraft operator on foreign engine parameter assessment services. The airline can assess the engine parameters independently. One of the next stages of further implementation of the ECTM system within the airline is the development of software that will automate the process of reading the aircraft engine parameters, conduct their analysis and correlate to the engine operation and maintenance documentation and issue a plan of corrective actions on the engine and its components.
Keywords: aircraft engine, parameters, regression analysis, basic values, maintenance.
