The subject of this research was the possibility of creating a control and verification apparatus (CVA) for ensuring full-scale autonomous tests of the regulator of a small gas turbine aircraft engine developed at the enterprise. The purpose of this study was to develop CVA (a modern small-sized hardware and software complex that allows automating the performance tests, which is carried out as during the production technological cycle of the regulator, as well as in operation) based on information about the aircraft engine characteristics, including refinement of its mathematical model based on experimental data. The tasks faced by the developers were to determine the optimal set of functions of the equipment, which would provide sufficient data for a reliable assessment of the regulator's performance based on the test results while minimizing the time spent and the probability of errors, and the implementation of the function of automated performance of complete regulator measuring channels calibration, including the pressure measurement channel (together with the pressure sensor) and the fuel flow measurement channel (with the sensor of the angle of rotation of the dosing element of the fuel dispenser). The applied methods are follows: at the first stage of design it was the analysis of available data on the processes that need to be automated, after that the experimental method of research the first sample characteristics and its interaction with the aircraft engine was applied at the developer’s test base (JSC “Element”) and at engine test stands of JSC "Motor Sich", and then – a method of statistical data processing, including refinement of the mathematical model of the aircraft engine. The results. The developed CVA consists of a hardware part structurally designed in the form of a CVA block weighing 1.7 kg with built-in software and a software product installed on a personal computer. The mathematical model of the aircraft engine integrated into the built-in software allows you to perform a full-fledged check of the regulator's functioning, in particular, at the start of the engine, at the maintenance of the specified operating mode, while ensuring protection against exceeding the permissible values of the parameters. The scientific novelty of the obtained results is the development of the CVA with an integrated engine mathematical model and a set of functions that provide a full autonomous regulator operability check, which was verified in the process of testing on real engine. The practical significance of the obtained results lies in the fact that the production and operation of the newly developed aircraft engine regulator is equipped with a compact and easy-to-use means of full-fledged operational automated control of its performance.
