In order to diagnose and predict the technical condition, it is reasonable to apply digital twin technology. The functioning of various components of aviation electrical equipment is determined by physical and chemical processes occurring in these objects. To model and analyze the dynamics of such processes, the authors have developed a method of mathematical prototyping of energy processes – a unified approach to building correct (not contradicting physical laws) models of processes of various nature. The equations derived by the method of mathematical prototyping make models with inputs containing measurable characteristics, and outputs containing controlled characteristics of the object. Such models are the mathematical basis of digital twins of aviation electrical equipment. Building of the mentioned mathematical models demands big computational expenses; hence there is a necessity of development of the programtechnological platform of digital twins, providing construction and storage of digital twins of aviation electrical equipment. The construction of digital twins is performed on the ground and the use of already constructed digital twins is performed on board the aircraft. The development of the concept of such a digital twin platform is the focus of this paper.","PeriodicalId":380541,"journal":{"name":"2023 XX Technical Scientific Conference on Aviation Dedicated to the Memory of N.E.

In work, taking into account the accepted initial conditions, limitations, and assumptions, the problem of optimizing the choice of the appearance of a multipurpose use of unmanned aerial vehicles system based on the cost of performing the target tasks solved during remote sensing of the Earth is solved. The problem is solved based on a generalization of dynamic thickenings of the design parameters of a multipurpose unmanned aerial vehicles system. The definition of the basic variant of a multipurpose unmanned aerial vehicles system is given in the form of a set (vector) of the design parameters that are part of the system. This task belongs to the class of functions of multi-criteria multiparametric multifactor identification of indicators and characteristics of complex organizational and technical systems and their structural and parametric optimization. The problem is solved based on a systematic analysis of the operating conditions of the unmanned aerial vehicles in various remote sensing variants by mathematical modeling (including simulation). The substantiation and selection of the appearance of the design vectors of parameters and the definition of critical characteristics (options) for the creation (modernization) of a multipurpose aerial vehicles system in the conditions of a multidimensional heterogeneous set of remote sensing targets are carried out. The choice of the vector of design parameters of a multipurpose aerial vehicles system allows you to determine the modification of each type of UAV, namely the design features and tactical and technical characteristics of the aerial vehicles. Based on the analysis of the functioning of a system of several types of aerial vehicles designed to serve a variety of purposes in the Earth’s atmosphere, the configuration (appearance) of this system is determined, which allows, under the conditions of accepted assumptions and initial operating conditions, to solve the target tasks with maximum probability and minimum cost. The solution of the target task is understood as the delivery of data collection platforms to specified areas of the World Ocean and the Earth’s surface. The problem is solved by considering the aerial vehicles parameters structural features, design, and functional limitations.","PeriodicalId":380541,"journal":{"name":"2023 XX Technical Scientific Conference on Aviation Dedicated to the Memory of N.E.

At the same time, the modern requirements for the time and cost of developing complex high-loaded items require a calculated analysis of the design behavior in the presence of plastic deformations, for example, in case of emergency. Description of the plastic deformation is complicated by more significant influence of the deformation rate, temperature, material anisotropy and other factors. The Johnson – Cook analytical model is used to simulate the material behavior under dynamic loading conditions accompanied by the intensive plastic deformation, which takes into account the effect of material loading speed and adiabatic heating for its hardening. It is also possible to use the Johnson-Cook tabulated model, which in comparison with the analytical one is more universal due to the use of the tabular or arbitrary method for setting deformation curves at different levels of deformation rates and temperatures.","PeriodicalId":380541,"journal":{"name":"2023 XX Technical Scientific Conference on Aviation Dedicated to the Memory of N.E.

The ups and downs of output are analyzed, the connection with the processes in the global aircraft industry is shown. It is noted that the growth in the production of passenger airplanes continued until 1980. During next five years it decreased by more than three times, this is the pre-perestroika period. During the time of perestroika, from 1986 to 1992, production grew again. A crushing decline in the passenger aircraft industry in Russia occurred in 1994–1996. The article lists its possible causes. It is shown that the developers responded to this decline with an increase in activity, which cannot be considered effective behaviour in a time of sales reduction and a shortage of working capital.","PeriodicalId":380541,"journal":{"name":"2023 XX Technical Scientific Conference on Aviation Dedicated to the Memory of N.E.

Vorobev","doi":"10.1109/TSCZh58792.2023.10233332","DOIUrl":"https://doi.org/10.1109/TSCZh58792.2023.10233332","url":null,"abstract":"The article analyses the transport system of Russia’s eastern Arctic regions, identifying its distinctive features and risks of use. The main features are that air transport has no alternative for the organization of passenger transportation, delivery of socially important urgent cargo and provision of sanitary aviation services. The provision of air service to remote settlements in the Eastern Arctic is hampered by: harsh natural and climatic conditions and difficult geological conditions, low population density and its dispersion over a large area, the lack of alternative options for local communication between most settlements and district airports. The lack of landing sites in settlements forces airlines to use helicopter, the flight hour cost of which in Arctic conditions is several times higher than that of light aircraft. As a result, local flights are irregular, with a frequency of one to three times a month. The low frequency of local flights leads to a decrease in air mobility of the population, which is currently between 0.3 and 0.6 trips per inhabitant per year. To solve this problem, the concept of aviation accessibility of Russia’s Eastern Arctic regions has been developed. The concept of regional aviation accessibility consists in structuring the functions and types of air transport services provided to different stakeholders of the region and forming a unified systematic approach to their implementation based on the assessment of aggregate demand.","PeriodicalId":380541,"journal":{"name":"2023 XX Technical Scientific Conference on Aviation Dedicated to the Memory of N.E.

The hybrid approach is based on the joint use of model-based and data-based methods. The main advantage of the methodology described in the article is determined by the use of a single mathematical apparatus in the implementation of both groups of methods. To demonstrate the performance of the methods, a methodical example of a lower-order high-speed rotorcraft dynamics linear model is considered. The results of symbolic and numerical simulation in case of flight control system failure show the operability of the proposed methods. The implementation of the approach being developed will lead to an increase in the levels of reliability and testability of the flight control system, as well as a reduction in its weight and cost due to the rejection, in some cases, of redundant hardware redundancy of the sensing and actuating subsystems, which currently has a 3rd or 4th multiplicity.","PeriodicalId":380541,"journal":{"name":"2023 XX Technical Scientific Conference on Aviation Dedicated to the Memory of N.E.

It is shown that with the direct synthesis of control, the optimal value of the quality functional is achieved by measuring the full state vector. Otherwise, firstly, the closed control system will not meet the required restrictions, and, secondly, the conditions of optimality of the specified quality functional are not met. An algorithm for restoring the full state vector is proposed, the estimation of the state vector is determined as a function of the discrepancy, defined as the difference between the measurement vector and its forecast. This algorithm differs from the known ones in that the control signal is formed by the measured components of the state vector of the system, and the missing components are replaced by the coordinates of an ideal closed-loop system.","PeriodicalId":380541,"journal":{"name":"2023 XX Technical Scientific Conference on Aviation Dedicated to the Memory of N.E.
