Currently, the use of aviation systems with unmanned aerial vehicles (UAVs) of various classes and purpose for the benefit of both special customers and civilian purposes has acquired particular relevance and practical significance. Modern UAVs, used both separately and as part of the group, can carry several target loads on board at the same time, built on various physical principles: multifunctional optoelectronic system, digital aerial photography system, on-board radar station, radio and radio reconnaissance system, communication system for transmitting data from target loads (sensors) to a mobile device (for example, a tablet) to a remote subscriber, etc. At the same time, the issue of determining the evaluation of the effectiveness of solving both individual target tasks of UAVs and finding an integral assessment of the effectiveness of using aircraft systems with UAVs when solving a set of target tasks (sequentially or sequentially-in parallel in time), taking into account their priority and a number of other factors, remains practically unlit. The scientific and technical article consists structurally of three parts and is devoted to the consideration of the issues of finding an integral assessment of the effectiveness of the use of aviation systems with unmanned aerial vehicles. In the first part of article [1], a scientific and methodological approach has been developed to determine estimates of the effectiveness of solving private target problems of radio communication and remote monitoring (by optical and radar means) by a complex with UAVs. The second part of the article presents a mathematical apparatus for assessing the effectiveness of solving problems of conducting radio-technical reconnaissance and aircraft destruction of targets. As a criterion for the effectiveness of solving all private target problems, a universal indicator of the probability of solving them has been adopted, which will ultimately allow for convolution and determine an integral assessment of the effectiveness of solving a whole set of target problems. The methodological apparatus developed in the article is universal and invariant to the input parameters, that is, the number of solved target problems, the stage of operation of the complex with UAVs, and can be easily adapted to the new conditions for the use of other complexes with UAVs. Within the framework of this approach, a mathematical apparatus for functional dependence of probabilities of solving particular target problems with design parameters of target loads in the UAV has been developed, taking into account the peculiarities of its functioning and in the conditions of existing restrictions and assumptions. The scientific and methodological approach allows already at the stage of formation of the tactical and technical task for the complex with UAVs to obtain quantitative estimates of the probabilities of solving private target tasks using the technical backlog of industrial enterprises for key components from the complex (target loads, a set of communication facilities, etc.). Finding effectiveness estimates in the group application of UAVs, as well as taking into account possible electronic counteraction, goes beyond the scope of this article and is the direction of further research on this topic.

Currently, the use of aviation systems with unmanned aerial vehicles (UAVs) of various classes and special purposes has gained particular relevance and practical importance in the interests of both special customers and civilians. Modern UAVs are used both individually and as part of a group, they can carry several target loads on board simultaneously, they are built on various physical principles: a multifunctional optoelectronic system, a digital aerial system, an airborne radar station, a radio and electronic reconnaissance system, and a system communications for transmitting data from target loads (sensors) to a mobile device (for example, a tablet) to a remote subscriber, etc. However, the question of determining the effectiveness of solving both individual UAV targets and finding an integrated assessment of the effectiveness of using aviation complexes with UAVs when solving a set of targets (sequentially or sequentially-in parallel in time) taking into account their priority and a number of other factors. This article structurally consists of three parts. In the first part, we can observe a scientific and methodological approach to determining the effectiveness of solving particular communication targets and remote monitoring by a complex with UAVs according to the probability of their solution is developed. In the framework of this approach, a mathematical apparatus has been developed for the functional depend-ence of the probabilities of solving particular target problems with the design parameters of target loads as part of the UAV, taking into account the peculiarities of its functioning and under the conditions of existing limitations and assumptions. The scientific and methodological approach allows already at the stage of the formation of the tactical and technical task for the complex with UAVs to obtain, using the calculation method, quantitative estimates of the probabilities of solving particular targets taking into account the technical backlog of industrial enterprises for key components of the complex (target loads, communications equipment complex, etc.). The methodological apparatus developed in the article is universal and invariant with respect to input parameters, i.e., the number of tasks to be solved, the stages of operation of the complex with UAVs, and can be easily adapted to new conditions of use. It should be noted that the result of the article is the methodological apparatus for finding exactly the integral estimate. Finding performance assessments for the group use of UAVs, as well as taking into account possible countermeasures, is beyond the scope of this article and is a direction of further research on this topic.

The relevance of the article is due to the importance of the development of export of high-processing industries. Objective: to develop methodological support for assessing the neo-industrial export specialization of regions and its determining factors. The research methods included identifying potential assessment parameters and testing their applicability based on the analysis of economic development statistics of the region selected as an example. The proposed methodological support for the assessment of neo-industrial export specialization includes its integral assessment, assessment of goods and services, assessment of the contribution of the high-tech component to the change in exports, ranking of regions by absolute values of high-tech exports. The method of assessing the factors of neo-industrial export specialization involves the assessment of indicators that identify these factors of exo-and endogenous order – the development of manufacturing production, innovation potential, transport potential, the development of the export support system, and the international demand for the region's products. The practical significance of the proposed methodological support lies in the fact that it makes it possible to analyze the neo-industrial export specialization of Russian regions and the factors of its development, and to identify and analyze possible directions of development in this area.


The article is devoted to dynamic capabilities manifestation issues as a mechanism for implementing the potential of an industrial enterprise. In this context, a methodical approach to managing the industrial enterprises potential is formed, the basis of which are dynamic capabilities indicators. The emphasis on the human factor is made as a basis for the development of dynamic capabilities. The issue of "weak signals" comprehension and detection in the role of organizational changes markers is investigated. Different models of change markers work and study, their role in mutual understanding of people and enterprises are considered. The active and accurate detection of these markers changes allows us to interfere into the processes course, adjusting them with the smallest consumption of forces, material, mental and spiritual resources. The algorithm for an industrial enterprise potential managing is constructed according to the criterion of dynamic capabilities, taking into account markers of organizational changes. The method of an industrial enterprise dynamic capabilities quantitative assessment is developed on the interaction of the dynamic capabilities level and their co-care with weak signals degree. Unlike existing ones, based solely on expert estimates, the proposed method uses statistical data, which allows you to get more objective result. The external weak signals environment changes predicting method using nonlinear dynamics tools, which allows you to identify the most significant organizational markers, to predict changes in the environment and take into account these changes in the process of strategic decisions acceptance. Methodological approach implementation allows an industrial enterprise to take preventive decisions that allow you to store and increase competitive advantages. The obtained research results practical significance is the possibility of using the developed methods in the context of making a strategy for managing the industrial enterprise potential in response to rapid environment changes. Obtained results build the principles of the organizational and economic mechanism for ensuring the effective use of the potential of industrial enterprises in the implementation of domestic economy development European vector.

There is a growing interest in using unmanned aerial vehicles (UAVs) in the most diverse application areas from agriculture to remote sensing, that determine the need to project and define mission profiles of the UAVs. In addition, solar photovoltaic energy increases the flight autonomy of this type of aircraft, forming the term Solar UAV. This study proposes an extended methodology for sizing Solar UAVs that take off from a runway. This methodology considers mission parameters such as operating location, altitude, flight speed, flight endurance, and payload to sizing the aircraft parameters, such as wingspan, area of embedded solar cells panels, runway length required for takeoff and landing, battery weight, and the total weight of the aircraft. Using the Python language, we developed a framework to apply the proposed methodology and assist in designing a Solar UAV. With this framework, it was possible to perform a sensitivity analysis of design parameters and constraints. Finally, we performed a simulation of a mission, checking the output parameters.

ABSTRACTThe range of small, electrically powered UAVs is still limited by the mass specific energy of batteries. This paper investigates the idea that, in cases where multiple aircraft must transit to the same location, savings in mass or an extension of achievable range are possible when they join wingtip-to-wingtip. The viability of joined flight is investigated by quantifying the relative magnitude of savings resulting from increased aerodynamic efficiency and that of penalties due to the increased structural and component weights. Through a parametric analysis the level of savings achievable is found to be greatly dependent on the proportion of the flight spent in a joined configuration and aircraft design parameters such as wing loading, aspect ratio and the added weight of the joining mechanism. A custom, multidisciplinary UAV sizing algorithm is presented and utilised to design several sample aircraft, featuring two different joining mechanism architectures. The results verify the findings of the parametric study and indicate that mass savings are possible only for moderate to low aspect ratios, with semi-permanent magnetic joining mechanism performing better than rigid structural ones, even when the joined fight segment accounts for only 30% of the total airborne time.

The use of unmanned aerial vehicles (UAVs) as a communication platform is of great practical significance in the wireless communications field. This paper studies the activity scheduling of unmanned aerial vehicles acting as aerial base stations in an area of interest for a specific period. Specifically, competition among multiple UAVs is explored, and a game model for the competition is developed. The Nash equilibrium of the game model is then analyzed. Based on the analysis, an algorithm for Nash equilibrium computation is proposed. Then, a game model with fairness concern is established, and its equilibrium price is also analyzed. In addition, numerical examples are conducted to determine the factors that affect the strategies (price, quality of service, and beaconing duration) of the UAV and to show how the expected profits of UAVs change with that fairness concern point. The authors believe that this research paper will shed light on the application of UAV as a flying base station.

T he dynamic development of the digital economy creates new business conditions that catalyze crossindustry cooperation of enterprises and accelerate technology transfer between various market entities. This determines the need for the efficient integrated structures in the industrial sector of Russia with high scientific, innovative, digital, and production capacity. The purpose of the research is to develop and operationalize a competitive model of the scientific and industrial complex in the digital economy. The content of the scientific and industrial complex is determined, and the differences between the complex and the industrial cluster are identified. The competitive advantages of a scientific industrial complex in relation to autonomous enterprises are highlighted. The scientific novelty and practical significance of the study unfold in the development of theoretical provisions and structural and functional parameters of the model of the scientific and industrial complex in the digitalization of the social economic systems, as well as a cluster analysis based methodological approach to its operationalization. A methodological approach to the operationalization of the model of scientific and industrial complexes performing in the digital economy includes four stages: 1) identifying the prerequisites for the integration; 2) choosing the goals for establishing a complex; 3) enterprises clusterization and modeling of scenarios for establishing a complex; 4) development of a complex’s functioning and development mechanism. The basic, industrial and technological, innovative digital, institutional and managerial, structural, financial and market criteria for clustering enterprises and organizations to establish a complex have been worked out. The approach was tested and options for establishing scientific and industrial complexes were modeled from cluster analysis of 37 enterprises of the Central Chernozem region of Russia by the G-means method. With the results of the analysis in mind, the authors recommended to set up radio-electronic, electrical engineering complexes in Voronezh region and a machine-building complex in Lipetsk region. The article offers a list of members, goals, types of strategies, integration projects and expected results of the modeled complexes performance. The model of the scientific and industrial complex and the approach to its operationalization can become a methodological tool for the management of enterprises when some options for setting up, organization types and scenarios for the development of integrated structures in the industry of Russia are considered. Further research is seen to be in developing the models of strategic and sustainable development during digital transformation of scientific and industrial complexes, as well as in developing organizational and economic mechanisms for institutional transformations of industrial enterprises in the digital economy.

The purpose of the research was to create an algorithm for determining and correcting the output parameters of the navigation module and the flight-navigation complex of unmanned aerial vehicles which provides control of an aviation gyro-stabilized platform with a multispectral optoelectronic system during flight and tracking various objects of observation.Principles of control of an aviation technical vision system located on an unmanned aerial vehicle on a two-degree gyro-stabilized platform with the possibility of full turn around two perpendicular axes along the course and pitch are considered. Stability of tracking of observation objects at a distance of up to 10000 m is ensured by the use of a multispectral optoelectronic system including a rangefinder, thermal imaging and two visual channels.Analysis of the object of observation and the method of its support are carried out. An algorithm is proposed for integrating a Global Navigation Satellite System and a strapdown inertial navigation system based on the extended Kalman filter which includes two stages of calculations, extrapolation (prediction) and correction. Specialized software in the FreeRTOS v9.0 environment has been developed to obtain a navigation solution: latitude, longitude and altitude of the unmanned aerial vehicle in the WGS-84 coordinate system, as well as the pitch, heading and roll angles; north, east and vertical components of velocities in the navigation coordinate system; longitudinal, vertical and transverse components of free accelerations and angular velocities in the associated coordinate system based on data from the receiving and measuring module of the Global Navigation Satellite System and data from the 6-axis MEMS sensor STIM300.

Abstract The possibility of ensuring the safety of flights of aircraft, such as helicopters, at low altitudes, where there is a high probability of unauthorized appearance of small-sized objects such as unmanned aerial vehicles, is being considered. The possibility of solving the problem of detecting such objects on the basis of radar soundings in the resonant frequency range of the UHF radio wave range is considered. Sub-band processing of the received signals is proposed, based on the division of the spectral definition area into sub-bands, for adaptation to the frequency response band and noise filtering. The mathematical apparatus of sub-band signal analysis using sub-band matrices has been developed. An optimal solution to the problem of filtering responses in given sub-bands is obtained. A procedure for processing the received signals is given when making decisions about the presence of a response in a given sub-band. Estimates of the probabilities of erroneous decisions are given for a given probability of errors of the first kind.
