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%.

The project is designed to develop the latest, competitive technologies and designs of stamping equipment for the manufacture of artillery shells, which is relevant to increase Ukraine's defense capabilities. Technology development is performed in two directions. The first age includes increased productivity and cost reduction through the use of the latest developments in hot extrusion of hollow semi-finished products and hot and cold stamping by drawing with thinning and crimping at the end of operations.

Drones are widely used to solve many practical problems. The main parameters of drones are flight range, load capacity, speed and shunting characteristics. Currently, the best technical characteristics are drones with permanent magnet motors and lithium-polymer batteries. Placing more pairs of poles on the rotor reduces the size of the motor while maintaining the same torque, but requires the use of more complex, spatio-temporal laws of voltage modulation and multichannel power converters, which slightly increases the weight of the power supply system. not used in practice.

The requirements for electric contact joints between workpieces in the core columns of Kastner furnaces are formulated. The choice of a material - graphite foam - for making electric contact gaskets is justified. Rational form and thickness of electric contact pads have been determined, the glue for their fixation between electrode blanks has been selected. A mold for forming electrocontact pads has been developed and prototypes of pads of different shapes, thickness and density have been made in order to check their suitability for forming Kastner furnace core under industrial conditions.

Methodological, mathematical, algorithmic and software maintenance and support services have been developed and improved for optimizing structure, parameters and operation modes of new and improved solutions in heating systems based on renewable energy sources and energy efficient technologies (low-energy houses, low-temperature heating systems and high- temperature cooling systems, heat pumps and cogeneration plants, thermal storages, etc.).

The essence of the development is to create and test the system of monitoring and analysis of electric networks modes of operation and automatic control of electric distribution networks based on new methods of processing data of synchronous vector measurements, as well as experimental validation of the developed technology to determine the features of its application in power grids with renewable energy sources.
The main results of the work are:

The concept of development of the theory of designing of manipulators of mobile robots on the basis of the put forward idea of division of processes into various groups - macroprocesses and microprocesses is offered. Effective theoretical methods of research of working processes on the basis of stochastic tensor fields, generalized functions and screw calculus adapted to the tasks of research of mobile robot manipulators are applied.
