Abstract. The study of the motion of a solid body in electric and magnetic fields is closely related to many applied problems that arise in the development of new machines and devices in various fields of modern technology. The lack of clean smoothness of the rotor surface can lead to fluctuations in the accuracy of the gyroscope due to the non-spherical electrodes, displacement of the center of mass of the Rotor in the suspension, which occurs during overload and vibrations of the base, as well as in the absence of a zero-electrode filling the interelectrode space of the suspension. The expression of the nutation angle is taken as a function of time and the time constant of the decay process of the nutation oscillations of the Rotor is determined. Taking into account the aspherization of the Rotor, deviations for a specific gyroscope were revealed.

Keywords: electrostatic gyroscope, electrode, rotor aspherization, inertial forces.

Abstract. The article deals with one of the important areas of application of uavs – thermal control of violations of hydro-insulation coating of heating mains. Mapping of the territory with heating mains in settlements can be performed by uav in automatic (overflight of the territory according to the set programme) or automated (UAV operator manually changes uav flight modes) modes. Such mapping or thermography in the specified modes is much more effective than the methods of heat pipelines bypassing by the control teams used nowadays. An approach for obtaining optimal trajectories of unmanned aerial vehicles (UAVs) during the formation of thermographic maps is proposed.
at the end of the paper it is noted that the estimation of the length of the uav motion trajectory and, consequently, of the flight time is given for the case of precise motion along a given trajectory without taking into account the influence of external factors: side wind, headwind, upward and downward air currents. It is possible to estimate the length of the perturbed trajectory for different permissible wind load using simulation modelling.

Keywords: unmanned aerial vehicle (UAV), ultralight unmanned aerial vehicle, thermographic maps, thermal imager, hazardous industrial facilities, heat network pipelines.

Abstract. This paper presents an innovative fractal approach to the cultivation of agricultural land using unmanned aerial vehicles (UAVs). An approach to analyzing the earth’s surface using fractal analysis is considered, including the Fraunhofer diffraction fractal and Sierpinski carpet scaling. Code for Arduino is provided that allows you to collect data from sensors and send it in real time to a smartphone via Telegram. For more complex data analysis and integration with machine learning systems, the Raspberry Pi is proposed, with code for collecting data from a camera and LiDAR, as well as for recognizing crops using TensorFlow. The focus is on the ability to transmit data in real time, which allows you to quickly respond to changes and analyze large volumes of data on more powerful equipment or a server.

Key words: fractal, unmanned aerial vehicle, artificial intelligence, mathematical modeling, differential equation, agriculture.

Abstract: Accelerometers are widely used in various devices related to displacement, tilt and vibration. The list of typical applications of accelerometers includes avionics, industry, household appliances, fall protection systems, medicine and sports, as well as information input devices. That is why it is important that the selected accelerometer fits all the specified parameters, for example, it is simple in design, has an increased sensitivity threshold and no stagnation zone. The choice of the optimal accelerometer for a particular product depends on numerous factors. At the early stages of accelerometer development, it is necessary to evaluate many factors, such as the expediency of costs and the relevance of this product, to check the comparison of characteristics with various analogues of domestic and foreign countries, as well as to assess the degree of risk in obtaining a number of characteristics, taking into account the achieved world level. When drawing up the terms of reference, it is also important to take into account all of the above factors. The accelerometer is designed to measure the parameters of translational motion and is used as a sensor for changing the position of the device in space.

Key words: accelerometer, acceleration, inertial mass, frequency spectrum, sensitivity threshold.

Abstract. The article prepared by the author is a study aimed at automating the diagnosis of subsurface stratifications on composite structures of aircraft that are formed during post-impact damage. This article presents the results of the tests – the blow was inflicted on “witness samples”, that is, from a composite material that is used in the designs of civil aircraft. The blow was applied with tips of various shapes and diameters, allowing to simulate the operational defects of aircraft as much as possible. The impact was carried out in the range from 5 J to 80 J, impacts below this limit do not lead to delamination of the composite material, impacts above the specified limit lead to cracks on the surface of the composite material and significantly change the shape of the structure, which is beyond the scope of this study. Using regression analysis based on the test results, the ratios of geometric variables of defects and shock effects were obtained, which allows modeling the width, depth and shape of the defect from the impact energy and vice versa. Based on the data obtained, the author has developed software in the Java programming language, which calculates subsurface stratification in post-impact damage based on geometric data of a defect on the surface of a composite material. Automation of the post-impact damage diagnostics process significantly reduces the likelihood of a subsurface defect on a composite material being missed by the engineering and technical staff of an aviation enterprise, and also automatically issues recommendations on the replacement or repair of an aircraft composite structure. The relevance of the study of composite materials is of particular importance in connection with the development of a completely new domestic liner MS21-310, in which the wing is made of multilayer carbon fiber. The developed software based on the test results will have an impact for the successful provision of after-sales operation of the aircraft and maintenance of airworthiness.

Key words: composite materials, aviation, defect, operation of aviation equipment, maintenance.
