Improvement of the information system of remote monitoring of the technical condition of gas turbine engines

The implementation in the information system for remote monitoring (ISRM) of the technical condition of gas turbine engines (GTE) of a new method (hereinafter referred to as the Method) for early detection of deterioration in the technical condition of the rotor supports of a power turbine (PT) GTE is considered. The method is based on an expert rule, which analyzes the parameters of the engine oil system. The distinctive advantages of the Method are the possibility of use when atmospheric conditions and engine operating modes change, as well as its versatility. Automatic monitoring of the technical condition of the GTE in real-time mode and automated analysis of changes in the historical values of its operating parameters depending on time, performed in the ISRM, make it possible to timely identify the deterioration of the technical condition of engine components and carry out their maintenance or repair. The structure and graphical user interface of the ISRM are considered. The algorithm that implements the Method is described in detail, the script in which this algorithm is programmed, and the graphical user interface created to display and analyze the results of applying the Method are described. The procedure for testing the ISRM functionality created for the application of the Method using the historical values of the GTE parameters is outlined. The implementation of the Method in ISRM showed its openness and versatility for the implementation of new methods for diagnosing equipment using algorithms for analytical processing of the values of its operating parameters.
