The influence of aircraft transmitter nonlinearity for different types of fading in the channel (Rayleigh and Rician) was studied and the possibility of correcting nonlinearity by using pre-distortion was revealed. The impact of space-time diversity (MISO 2 × 1) for different types of fading in channels was investigated. The effect of the Doppler frequency shift on the operation of communication channels was analyzed.Item AIRCRAFT NAVIGATION EFFICIENCY IMPROVING DURING LANDING USING SATELLITE NAVIGATION SYSTEM(Вісник Національного Авіаційного Університету, 2017-12) Kharchenko, Volodymyr; Konin, Valeriy; Olevinska, Tetiana; Харченко, Володимир Петрович; Конін, В.В.; Олевінська, Т.І.; Харченко, В. П.; Конин, В.В.; Олевинская, Т.И.; Харченко, Володимир ПетровичPurpose: Two algorithms have been considered in this article. Both of them make possible to improve aircraft navigation efficiency during landing by satellite navigation system signals. The first algorithm describes creation of two reference planes in space using measured coordinates of four points on the runway and the subsequent calculation of the aircraft horizontal and vertical angular deviation from these planes. The second algorithm describes an autonomous integrity control in the aerodrome area when four satellites are visible. Methods: methods of experiment planning, analytic geometry and linear algebra have been used. Results: obtained a new experimental data. Discussion: The results of experimental research of the first algorithm showed the principal possibility of deviation calculation in this way. It is shown that implementation of this technology will make it possible to increase the efficiency of small aircrafts navigation during landing at aerodromes and landing areas that are currently not equipped with radio equipment for instrument landing. The results of research of the second algorithm showed that it allows reducing the number of satellite navigation system failures and also enhances navigation efficiency. These results can be used in the aerospace sector for reducing the number of small aircraft non-flying periods.Item Application of Imprecise Models in Analysis of Risk Management of Software Systems(Вісник Національного Авіаційного Університету, 2017) Харченко, Володимир Петрович; Kharchenko, Volodymyr; Alexeiev, Oleg; Rudas, Sergiy; Kozhokhina, Olena; Алексєєв, В.М.; Рудас, C.І.; Кожохіна, О.В.; Харченко, В.П.; Алексеев, В.Н.; Рудас, С.И.; Кожохина, Е.В.The analysis of functional completeness for existing detection systems was conducted. It made it possible to define information systems with a similar feature set, to assess the degree of similarity and the matching degree of the means from the "standard" model of risk management system, that considers the recommended ICAO practices and standards on aviation safety, to justify the advisability of decision-making support system creation, using imprecise model and imprecise logic for risk analysis at aviation activities. Imprecise models have a number of features regarding the possibility of taking into account the experts’ intuition and experience, the possibility of more adequate flight safety management processes modelling and obtaining the accurate decisions that correlate with the initial data; support for the rapid development of a safety management system with its further functionality complexity increase; their hardware and software implementation in control systems and decision making is less sophisticated in comparison with classical algorithms.Item COMPLETE SEPARATION OF THE VERTICAL AND HORIZONTAL INDEPENDENT COMPONENTS OF THE FLIGHT IN POLICOPTER UAV NAU PKF "AURORA" AND MATHEMATICAL MODEL OF THIS FLIGHT(Вісник Національного Авіаційного Університету, 2017) Харченко, Володимир Петрович; Kharchenko, Volodymyr; Nakhaba, Alexandr; Нахаба, О.О.Purpose: This article presents a mathematical model and the experimental results of automatic flights of the policopter UAV NAU PKF "Aurora" of oktacopter scheme with additional elektroimpeler engines of horizontal thrust. Methods: UAV NAU PKF "Aurora" is developed for experimental flights in manual, semiautomatic and unmanned modes. The uniqueness and scientific novelty of data of flight testes is in a complete separation and isolation of vertical and horizontal components of the flight, which enables a fundamentally new way of moving of vehicle in the aerial space. This approach gives a ability to obtain all advantages and to eliminate disadvantages of helicopter and airplane in fundamentally new aircraft by structure and by function – namely in the policopter flyer with additional independent engines of the lateral thrust. Results: Obtained a new experimental data that allowed to better understand the nature of the physical forces, providing the flight of the policopter. Discussion: Revised a physical basis of the airscrew (propeller), namely on the example of flight of the policopter proved that most of the thrust of the propeller provided by the mechanical impulse (kinetic energy Ек=mv2/2) by the impulse, that a airscrew receives at his collisions with air molecules,but not by the gradient of air pressure below and above the airscrew. Is put forward a hypothesis of gravitational nature of the flight and introduced the notion of "functional antigravity", that a force completely identical in function and opposite on the direction of the force of gravity (gravity force). Deduced a mathematical formula of "functionally antigravitational" transport, namely:G·M·m/R2= mI·v2/2 – for the flights of the aircraft with a mass m over universal astronomical body with a mass M, and m·g = mI·v2/2 – for the flights of the aircraft with mass m over a planet Earth.Item FACTORS BEHIND EFFICIENCY OF INTERACTION BETWEEN REMOTE PILOT AND UNMANNED AERIAL VEHICLE(Вісник Національного Авіаційного Університету, 2017) Kharchenko, Volodymyr; Мatiychyk, Denys; Харченко, Володимир Петрович; Матійчик, Д.М.Objective.

At present time, aviation is an ultra-safe system, (i.e. a system that experiences less than one catastrophic safety breakdown every one million production cycles). But, unfortunately, we can never state that aviation activities will be absolutely safe. In current conditions the increase of the civil aviation safety level is one of the principal objectives of the world air transport development. The paper pays special attention to the civil aviation threats and risks in the context of globalization processes. The investigation deals with problems of global implementation of Annex 19 to the Convention of the International Civil Aviation. Present research paper discusses new theoretical approaches to searching for methods to assess the “safety space” of civil aviation activity. Special attention is paid to an effective test, proposed by A. Wald.Item ГРАФОАНАЛІТИЧНІ МОДЕЛІ ПРИЙНЯТТЯ РІШЕНЬ ЛЮДИНОЮ-ОПЕРАТОРОМ АЕРОНАВІГАЦІЙНОЇ СИСТЕМИ(Вісник Національного Авіаційного Університету, 2011) Харченко, Володимир Петрович; Шмельова, Т.Ф.; Сікірда, Ю.В.Наведено фактори, що впливають на людину-оператора, яка приймає рішення, в аеронавігаційній системі.
