Calculation and analytical method for identifying the structure and parameters of the system of wave equations of GTEs as an object of control, monitoring and diagnostics

Abstract

A system-semantic approach to the formation of an automated method for identifying the structure and thermogasdynamic parameters of a system of wave models of basic units in a gas turbine engine is considered, based on its 4d – 1d computer models. It is shown that this approach makes it possible to provide the required level of expansion and formalization of knowledge in the form of a variety of system models of digital twins (DT) of real and virtual objects and their processes while preserving their causeand-effect relationships. The logic of representing elements of system models of gas turbine engine units in the spatial-temporal Minkowski basis based on their wave functions is expanded. The objective need for the formation and application of a subjectoriented formal (generative) metalanguage is shown. An example of the application of this approach to identifying the structure and parameters of the wave model of an axial compressor as part of a gas turbine engine as an object of control and diagnostics is considered
