Experimental samples of flat-oval thermosyphons (TS) with partial transverse rectangular and corrugated finning and samples of round TS with inner intensifiers of heat transfer in evaporation section (ES) were developed and fabricated. They are intended for functioning in heat exchangers (HE) utilizers of heat wastes in ventilation systems. It was shown, that freon R134a is the most optimal heat carrier for TS functioning in conditions close to these in ventilation systems from the point of boiling temperature and safety of application.

A novel theoretical and practical development for highly efficient traction electromechanical systems based on the induction and synchronous reluctance motors is presented, which allows to overcome the problem of permanent magnets limited availability. New nonlinear and adaptive control methods have been developed for traction electrical drives and hybrid energy storage systems based on batteries and ultra capacitors. The theory of vector control systems design was extended to class of highly saturated electric motors using their improved mathematical models.

Scientific knowledge was obtained regarding the kinetic complications of direct electrochemical oxidation of nitrogen oxide on metal modifications and the possibility of oxidation of nitrogen oxide by a homogeneous iodine-iodate mediator redox system in an aqueous solution was thermodynamically proven, the kinetic feasibility of which was experimentally proven due to the revealed exclusive selectivity of semiconducting titanium dioxide on the surface of the titanium base to halogen mediator reduction reactions.

The work is aimed on the improvement and testing of the subsystems of the university nanosatellite (NS) of Cubesat format through the development, modeling and research of service subsystems to ensure the payload - an optical-electronic scanner with the ability to image the Earth's surface in the visible light range with the resolution of 15m to 30m when operating in orbit with an altitude from 400 km to 700 km, by the efforts of students, master's students, post-graduate students and research staff of Igor Sikorsky Kyiv polytechnic institute.

An information system for monitoring changes in the land cover of the territories based on satellite data was created. The system is integrated into the Information and Analytical Situation Center of the Igor Sikorsky Kyiv Polytechnic Institute.

A complex of methods and models has been developed, based on which the degree of transformation of land cover types is evaluated, critical changes are identified, and their classification by type of transformation is carried out. Methods used to identify transformations:

On the base of the results determined by using modern physical material science methods scientific principles referred to relationships of structure, phase composition, physical and mechanical properties formation of frame metal-ceramic composites based on tungsten carbide with a multicomponent high-entropy alloy (HEA) binder during high-speed electron-beam and induction sintering has been developed for the first time and will play an important role in deepening the understanding of the processes of structure formation in dispersed heterogeneous systems.

In the scope of the work, an analysis of the water supply of residents of the Donetsk region and other regions of Ukraine with natural and anthropogenic sources of water suitable for further processing was carried out, the chemical composition of waters of various origins was determined, and the possibility of their additional processing to provide consumer properties was determined. Possible methods of pre-treatment of water are proposed, which ensure long-term and uninterrupted operation of baromembrane installations.

The perspective of using combined thermal, ionic and deformation effects as a tool for purposeful modification of the structural and phase states of the near-surface region of a wide class of structural and functional metal materials to increase the durability, quality and reliability of parts, products and structures of transport engineering and medicine has been proven. Steels 40X13, 08X18N10, 9Г2ФА, aluminum alloys AMg6, D16, cobalt alloy Co-Cr-Mo-W, brass LS59-1, titanium alloy VT6, multi-component alloys Fe81B7Si1P10Cu1, CrMnFeNi2CoCu, etc. were studied.

The main processes of manufacturing unicycles are mechanical processing from a monolithic workpiece, which is highly labor-intensive for aluminum unicycles up to 200-250 hours, and for titanium 250-350 hours on CNC machines. The use of new knowledge reduces the labor intensity of production by 40-80%.
