Calculation and analytical method for identifying the structure and parameters of the quadratic dynamic model of the GTE compressor as a sub-object of control, monitoring and diagnostics

Abstract

A system-analytical approach to identifying the structure and thermogasdynamic parameters of a gas turbine engine compressor as a dynamic sub-object of control, monitoring and diagnostics is explored, based on the analysis of 4d – 1d computer models. It is shown that this approach makes it possible to build a dynamic model of a gas turbine engine compressor as a subobject of control, monitoring and diagnostics with a quadratic structure, with the possibility of being integrated into the digital systems of automatic control, monitoring and diagnostics already at the design stages. It is shown that this model can increase the control efficiency and reliability of gas turbine engines by increasing the depth of monitoring and diagnostics of thermogasdynamic processes in real time. An example of identification of the structure and parameters of a dynamic model of a gas turbine engine compressor as a sub-object of control, monitoring and diagnostics is considered, based on the calculation of parameters using the computer systems DVIGwT, GasTurb, etc.
