Approximation function identification and optimization in the tests data analysis of GTE components

In the paper we model the behavior of the loss coefficient in the turbine grids of a gas turbine engine (GTE), depending on its parameters. Factors affecting the operation of gas turbine engines and methods for processing test data of gas turbine engine components are considered. An algorithm was developed and the corresponding software for analyzing the bench test data of a gas turbine engine was implemented. The program allows us to get a mathematical model that describes the behavior of the loss rate of the turbine stage, depending on its parameters. The program provides the ability to customize the process of finding the coefficients of the regression model and the process of optimizing the resulting model. It is possible to save the processing results to a text file.
