(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 Петрович
Purpose: 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.
ANALYSING SURFACE MOVEMENT DELAYS IN AN AIRPORT
(Національний авіаційний університет, 2014-04-04) Kharchenko, Volodymyr; Tapia, Katerina; Shvets, Alexander; Харченко, Володимир Петрович
Delays can be introduced into the system from any overloaded or poorly performing service component. The stages of service that constitute an airport are arranged in a network. This network can be thought of as a single macroscopic server. As for airport the main bottleneck is the runway system. The variable and often relatively high demand due to weather conditions, made it obvious that overloaded runway can explain a majority of the surface – movement delays encountered at airports. Before departure and after arrival aircraft pass stages of taxi – out and taxi – in processes that can influence on rate of traffic in airport and, of course, can be the reason of delays. If the same runway is being used for both arrivals and departures, the tower controller only allows takeoffs to occur during gaps in the arrival sequence. Departing aircraft are often delayed while waiting on the taxiways or at terminals for takeoff clearance. Thus, surface movement delays in airport are analyzed
Analysis of layout and justification of design parameters of a demonstration aircraft based on solar cells
(2020) Isaienko, Volodymyr; Kharchenko, Volodymyr; Matiychyk, Mykhailo; Lukmanova, Inessa
The development of aviation vehicles on SC (solar cells) requires, in particular, evaluations of the technical decisions made regarding the layout of future developments and obtaining their design parameters. Accordingly, it is important to take into account previous developments in the various aviation engineering fields relevant to new aviation vehicles on the SC. Thanks to a detailed analysis of the flight and performance characteristics of widely known aircraft models on the SC from the 70s of the 20th century to the present, a picture of the distribution of aerodynamic schemes and important design parameters with conclusions regarding their choice is obtained. For aircraft on SC, the corresponding boundaries of their work in height and speed are determined in comparison with long-range aircraft. Also, acceptable values of unit load per unit area and specific power have been obtained that allow aircraft to be lifted on the SC at altitudes of at least 20 ths.m. These altitudes are promising for longhaul aircraft to be operated on to SC for the purpose of performing the functions of an "aerodynamic satellite" or the so-called "pseudosatellite". The design parameters of the "pseudosatellite" demonstrator on the SC with a wingspan of 11m and a starting mass of 16 kg were obtained.

(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.

(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.

(Wroclawskie Wydawnitstwo Oswitatowe, 2022) Kharchenko, Volodymyr; Bugayko, Dmytro; Paweska, Marcin; Харченко, Володимир; Бугайко, Дмитро; Павеска, Марчін
Rozwój ludzkości oznacza ciągłe pokonywanie problemów i wyzwań. Te, z którymi mierzymy się dziś, dotyczą zróżnicowanych dziedzin i aspektów życia. Największe współczesne światowe wyzwania wiążą się ściśle z rozwojem technologii, a ich przezwyciężanie wymaga określonych zmian w nauce i kształceniu, czyli doskonalenia metod zdobywania nowej wiedzy. Naszym zdaniem bardzo wiele zależy od rozwoju takich systemów socjotechnicznych, jak transport i przemysł lotniczy, energetyka jądrowa czy przemysł chemiczny. Chcąc sprostać wyzwaniom w przyszłości, będziemy musieli stale rozwijać dziedziny nauki koncentrujące się na perspektywach światowej gospodarki i technologii. Równocześnie konieczne będzie właściwe kształcenie kolejnych pokoleń naukowców, ekspertów, specjalistów i menedżerów, zapewniające odpowiedni poziom wiedzy i konkurencyjności. Transport lotniczy jest jednym z kluczowych elementów współczesnej gospodarki. Bez względu na to, czy mówimy o pasażerach, czy towarach, możliwość szybkiego i bezpiecznego transportu cennych zasobów na duże odległości poprawia jakość i standard życia ludzi na całym świecie. Najważniejsze cechy transportu lotniczego to bardzo duża szybkość, wysoki poziom niezawodności, wysoki koszt oraz średnia elastyczność. Innym ważnym aspektem podróży lotniczych jest stosunkowo wysoki poziom bezpieczeństwa. Wynika to nie tylko z faktu, że same samoloty jako maszyny stają coraz bezpieczniejsze, ale także z danych pokazujących, iż transport lotniczy to najbezpieczniejsza forma podróżowania. Wszystkie inne codzienne rodzaje transportu, od poruszania się na piechotę po jazdę samochodem, są ciągle znacznie bardziej ryzykowne.
