Purpose. The purpose of this work is the formation of conceptual approaches to the construction of an effective integrated system of simultaneous synchronized control of the movement and suspension of a maglev vehicle – a magnetoplane. Methodology. The paper uses a technique for simultaneous control of the movement and suspension of a maglev vehicle with the mutually coordinated application of both levitation methods, electromagnetic and electrodynamic, through individual control of the energy supply of each track coil. Findings. The conceptual control principles of a traction-levitation system in a hybrid mode of its operation are substantiated. The interaction of a track structure with a vehicle on an electrodynamic suspension with a linear drive is disclosed and the features of the implementation of the power unit are highlighted. Originality. It is shown that a significant improvement in maglev technology can be achieved due to the mutually coordinated combination of electromagnetic and electrodynamic methods of magnetic levitation and the use of a fundamentally different architecture for constructing a MAGLEV track. It is constructed not from long sections with three-phase power windings, but from discrete ones, they are also linear engine traction coils, and a component (load) of a solar track power plant located along the overpass. The power plant includes a photovoltaic module (solar battery) that converts solar energy into electricity, a storage device and an inverter. This construction makes possible independent supply of each travel coil and its autonomous control with the ability to switch to traction or levitation mode. The control concept is that each track coil can participate both in the creation of a static suspension due to the interaction of the magnetic field of the onboard superconducting magnet and the magnetic field of the track coils when a certain amount of direct current is applied to them, as well as the dynamic suspension provided during the train movement as a result of the interaction of the magnetic field of the onboard superconducting magnet and the magnetic fields created in the track coils by currents induced in them when the magnetic fields of the onboard superconducting magnet intersect. Practical value. The results are of practical value, as the use of such complex control system of the suspension and the magnetic plane movement will significantly improve the quality of MAGLEV technology, increase the efficiency and reliability of high-speed land transport based on electrodynamics levitation using superconducting magnets.
An analysis of the transport systems current state in Ukraine has shown that the main problem in this area is the lack of transport infrastructure capacity, due to low route speeds for most transport modes and low levels of traffic organization and management. The level of rail container transport, the most common and perspective type of freight transportation is also low compared to European countries. Therefore, the main idea of the article is to justify the need for the introduction of fundamentally new transport technologies that will help reduce or eliminate the problems of freight transport, and so the article is relevance. The possibility of using magnetic technologies that exclude contact of a vehicle with a road structure, for freight transportation is investigated. The authors consider the main structural elements, functions and possible options of the magnetic levitation transport system of freight transport. The practical value of the work is that the use of magnetic levitation container platforms will significantly increase the intensity and speed of the conveyor sending of each container with a decrease in energy consumption, which will significantly affect the improvement of cargo logistics. The main results of the work: the conceptual bases of construction of unmanned magnetic levitation vehicles and the main systems of their infrastructure are formulated, it is shown that the implementation of the function of drone for the vehicle is possible only if permanent levitation in all sections of the freight transportation will be provided.
The article proposes a way to determine the position of the crew of the tape recorder using the method of rangefinder. The basis of the developed idea is the use of emitters with which you can register the rotational movements of the crew (pitch and dredging), as well as to register the roll. According to the results of the research, the following is substantiated: phase rangefinder with one emitter on the crew platform allows to determine the position of the crew on the race, its displacement in the horizontal plane relative to the longitudinal axis of the track structure and the height of the suspension between the crew bottom and three rotational movements (pitch, digging and roll). The novelty of the work is to substantiate the method of continuous positioning of high-speed magnetic levitation vehicle on 6 degrees of freedom based on phase rangefinder for arbitrary configuration in three-dimensional space of a fixed overpass and the integrity of the navigation system. The considered method of navigation is intended for use in high-speed transport ground systems on a magnetic suspension, the organization of the automated control of movement of wheeled transport on local platforms of industrial function, the organization of high-speed small-scale municipal transport of individual use.

Проблематика. РЛС подобного типа относятся к большим сложным и наукоемким техническим системам. Новизна применяемых научно-технических решений, длительные сроки проектирования и изготовления РЛС обнаружили невозможность применения существующих стандартов разработки и постановки на производство и обусловили необходимость создания нового стандарта. Цель. Анализ и обобщение особенностей разработки и изготовления систем контроля космического пространства на базе отечественных радиолокационных средств. Материалы и методы. Применен метод системного анализа особенностей отечественной школы радиолокационных систем контроля космического пространства с использованием научно-технического задела и материалов Главного конструктора по обеспечению эффективного решения возникающих специфических проблем при создании новых поколений РЛС. Результаты. Показано, что для реализации информации, получаемой существующей РЛС, необходимо обеспечение ее конкурентоспособности на возрастающем рынке таких услуг, что возможно как за счет повышения технических характеристик существующих средств, так и благодаря разработке новых. Исходя из специфических особенностей, неизбежно возникающих на разных стадиях жизненного цикла РЛС, наличия достаточного объема научно-технического задела (НТЗ) и опыта создания как данной, так и последующих поколений РЛС, представлен ряд предложений, направленных на эффективное решение вопросов контроля космического пространства (ККП) радиолокационными средствами. Выводы. Обеспечение интеграции и поставки наукоемкой продукции отечественных радиолокационных средств в международные структуры ККП возможно только на путях эффективного использования и стабильного наращивания потенциальных возможностей имеющихся средств на базе существующего научно-технического задела с учетом специфических особенностей построения РЛС контроля космического пространства. Изложены отдельные специфические особенности возникающих проблем и возможные пути их эффективного решения могут быть полезны широкому кругу разработчиков сложных наукоемких систем.
