The subject of the study is sustainable reverse engineering and conventional reverse engineering of aviation equipment (AE) samples. The object of the study is the geometric accuracy of the extracted portrait of a part of a complex shape in comparison with the constructed analytical standard (AS). The work is aimed at researching the methods of sustainable reverse engineering and conventional reverse engineering on the example of the digitization of the box of the AE steering machine, chosen as a part of a complex shape. For this, a portrait of the "*.stl" and AS format file was created and compared by performing a control operation with the determination of the time spent. A structural and technological analysis of the box of the AE steering machine was carried out, which showed that the box has through holes of various diameters (from 10 to 41.6 mm) and shapes (square, trapezoidal, round); thin walls between holes (up to 1.6 mm); right angles and their rounding radii (up to 1–4 mm); the thickness of the body walls is 2.4 mm, etc. 3D scanner – ARTEC SPACE SPIDER (Luxembourg) was selected and scanning was performed. According to the analysis of research methods of reverse engineering, it was established that the use of permanent and conventional reverse engineering allows, in the first case, to quickly manufacture a part by 3D printing or milling on CNC machines, and in the second case, to create its AS with the provision of the specified geometric accuracy. The difference in time between permanent and normal reverse engineering was 8 hours in favor of the former. Control of the ideal portrait according to the AS of the AE steering machine body showed the maximum deviations from –0.30 mm to +0.23 mm and the minimum deviations from –0.04 mm to +0.08 mm. The smallest indicators were observed on vertical and horizontal planes, and the largest - in cities with plane slopes, corners and small radii. This made it possible to establish that the existing capabilities of the Geomagic Design X software for correcting the received portrait of the "*.stl" format file currently do not guarantee the provision of geometric accuracy requirements (up to ±0.5 mm) for the manufacture of an experimental part of a complex shape – the AE steering machine body with 3D printing. The resulting ideal portrait can be used to manufacture a part by milling on CNC machines, taking into account deviations at the stage of process model formation, which can become the topic of further research.

A lot of publications are devoted to the study of gear transmission, which cover all the features of their design, operation and repair. An in-depth analysis of factors that were not taken into account a decade ago was carried out. The efficiency of the drive, taking into account air resistance, and the stress-strain state of the tooth, taking into account centrifugal deformations, were determined. Thus, there are constant complication of the tasks that researchers set themselves. At the same time, recent achievements in the natural sciences have led to a narrowing of the field of use of gears. Thus, the electric motor replaced the internal combustion engine, which was an important object of research for mechanical engineers. The widespread use DC motors with speed control has led to the abandonment of gearboxes in electric vehicles and metalworking machines. Application of mechanical gears in devices. starting with ordinary watches, and ending with the mechanisms of computer disk drives, is a thing of the past. Further in-depth studies of gears, in some cases, don’t make sense, since the object of research disappears. It is important to identify areas of research that remain relevant in the 21st century. First of all, these are transmission studies that use the latest achievements in other areas of science. These include: the use of new materials in gears; use of new forms of tooth profiles and longitudinal forms of the tooth, without technological restrictions; analysis of the operation of the gear drive based on indirect indicators - the spectrum of noise and thermal fields of housings. Also, the study of gears in which the tooth is a working body, such as chain conveyors and pumps, will never lose relevance. Or, in which the gear train combines a number of functions, for example, the worm gears of elevators, which reduce the angular velocity and serve as a fuse.
