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.

Abstract. The electrical system is one of the main components of the aircraft, most of the systems and components of which are powered by electricity. The electrical system of an airplane can be compared to the human nervous system, without electricity, organs and body parts would not function. However, in case of such an emergency, the aircraft is equipped with a battery that can power the aircraft for 30minutes – the maximum time until an alternative airport is found and the aircraft cannot land.

Abstract. Modernization of life support systems for the crew and passengers of aircraft is one of the most important aspects of aviation security. Here are some of the advances in technology thathave improved the survival of modern aircraft: oxygen systems, Cabin Pressure Control, Emergency Evacuation Systems, advanced filtration systems. In general, the modernization of life supportsystems for the crew and passengers of aircraft has significantly increased the safety and comfort of ir travel. Thanks to these advanced systems, passengers and crew can feel safe and confident during the flight.As for the technologies considered in this work, which are used both on Earth and in space conditions, the integration of life support systems for space flight into aviation can have both scientific significance and practical significance.From a scientific point of view, it is more efficient to integrate life support systems from the pace industry into aviation, and more stable life support systems can provide new data on the impact of various factors on a person during high-altitude flights. From a practical point of view, integrating life support systems from the space industry to aviation can significantly improve flight safety and comfort, especially in conditions of long-distance flight.

Abstract. Multiple input multiple output (MIMO) transmission can be used to increase the capacity of visible light communication (VLC) systems. This approach is well compatible with theuse of micro light emitting diode (µLED) arrays.In this paper, we demonstrate a VLC-MIMO imaging system using a 2D array of individually addressable microLEDs and an integrated CMOS-based receiver. The total data transfer rate of ~920 Mbps is realized using four parallel channels at a distance of 1 m. Further increase in data transfer rate is possible by optimizing the system components and operating conditions.

Abstract. This paper shows for the first time that the problem of continuous downholemonitoring in the oil and gas industry is effectively solved through the use of visible lightcommunication (VLC). As a reliable, flexible and low-cost method, VLC can meet the critical needof operators to maintain production efficiency and optimize gas well performance. The proposed VLCsystem uses a Light Emitting Diode (LED) transmitter and a highly sensitive single photon detectionreceiver called a Single Photon Avalanche Diode (SPAD). The latter plays an important role inenabling communication over long distances, and the fact that there is no ambient light in the gas pipeis exploited.In particular, the absence of ambient light provides a high signal to noise ratio (SNR) in areceiver that operates in photon counting mode. In this study, the bit error rate (BER) performance ofthe system is simulated for a 4 km long metal pipe. The proposed system is shown to be more energyefficient than traditional methods, which is important because the transmitter is assumed to be batterypowered. In addition, the theoretical BER performance is calculated and compared with simulationresults.

Abstract. Lithium-ion batteries have become an indispensable power source for unmannedaerial vehicles and other portable electronic devices, electric vehicles, and stationary energy storagesystems. However, their performance and safety can be compromised under high load conditions,which can lead to catastrophic failures, such as thermal runaway and fire. To prevent such incidents,it is crucial to develop reliable methods for predicting the failures of lithium-ion batteries under highload conditions. In this article, we will discuss the prediction of failures of lithium-ion batteries underhigh load on the BMS (Battery Monitoring System) charge boards in unmanned aerial vehicles(UAV).
