The master's dissertation consists of four sections, 84 pages, 25 figures, 28 tables. In the process of writing, 11 literary sources were processed.

In the first section of the dissertation, an analytical review was conducted, in which the object of control was considered, the methods of non-destructive testing were analyzed, and their advantages and disadvantages were considered. The second section includes the calculation of a combined piezoelectric transducer. Also in this section calculations of acoustic and electroacoustic paths were carried out. The structural scheme of the device is developed, and on its basis functional. All nodes of the scheme are calculated and coordinated. In the third section, calculations and simulations of an automated "manual" manipulator in the SolidWorks environment were performed. The fourth section is devoted to the development of a startup project: market analysis, search for competitors, etc. Based on the calculations, the electrical circuit diagram was designed and developed.

The master's dissertation consists of six chapters, 90 pages, 22 illustrations, 30 tables, 25 sources of literature have been studied.

In the first section, an analytical review was conducted, in which the object of control was considered. The analysis of smoke detection methods is carried out. In the second section, the optical system of our smoke chamber was calculated. A lens for external fire alarm has been designed and modeled. In the third section the electric scheme was developed, all important accessories which are necessary for stable work of the device are selected. In the fourth section the complete design of our device is constructed. The fifth section describes the software that fully satisfies us and meets our requirements for an automated system. The sixth chapter outlines the main advantages of our project over competitors. Advantages of using fire protection systems rather than single devices is a complete connection that will signal to devices that do not detect smoke command to notify the fire, in one installation. That is, if the owner of the house does not hear a signal from the sensor which detects smoke, he will hear it from a device that is nearby.

In industry, one of the most common materials used is rolled aluminum sheets. This material needs to be controlled very carefully and often, as it is very often used in aviation. When controlling such sheets, the main problem is the speed of control, because such sheets have significant dimensions. The use of a computerized eddy current control system with matrix transducers will significantly reduce the time required to localize the defect area, which in turn will increase the speed of inspection.

The master's dissertation contains 82 letters, 25 figures, 23 tables, 18 sources according to the list of references.

Key words: eddy current control, structural elements, aircraft, hodograph, defect dimensions, automation, material degradation, cracks.

The dissertation presents an analysis of structural elements as an object of NC control. The expediency of using eddy current non-destructive testing to detect defects such as surface and subsurface fatigue cracks and evaluate their parameters has been confirmed.

A review of possible methods of processing the received signals according to the available hodographs of the relative applied voltage. Types of overhead and through-flow eddy current converters are considered. The analysis confirmed the feasibility of using an eddy current transducer of the transformer type with differentially connected measuring coils.
