The basic regularities of the physical nature of strength of directionally solidified eutectic alloys (LaB6-MeB2, B4C-MeB2, Ti-TiB, Mo-Si-B, etc.) have been defined by systematic studies of the influence of the nature of the matrix and reinforcing phases, their structural-geometric characteristics, and stress-strain state on the temperature dependence of mechanical characteristics of composite materials.

Statement and performance of the research under consideration are substantiated by: (1) vital necessity of support and strengthening of safety barriers in nuclear power engineering by passive methods heat removal; (2) availability of vaporization-and-condensation type (VCT) systems creation for heat removal and thermal shielding; (3) significant limitation of the noted R&D and absence of its implementation in nuclear power technologies; (4) extremely insufficient experimental data base as to core temperature mode in the SCW reactors of a new generation resulting in absence of reliable

A package of applied programs for calculating and designing a mobile robotic complex based on a chassis of high cross-country ability with a wheel-walking twin-rollers driver. Effective methods for solving a number of applied problems are proposed, in particular, analytical and numerical modelling of chassis’s dynamics during overcoming obstacles with comparable sizes; identification of loads applied to chassis’ parts by numerical methods or by values of corresponding sensors; predicting the residual life of parts under intense external loads.

As a result of the work, an energy saving power supply system was created for the university space vehicle - nanosatellite (NS) PolyITAN-2 of the 2U CubeSat format when solving an important applied task - full-scale nanosatellite measurements of the parameters of the lower Earth thermosphere in the international project "QB50". Energy saving is a necessary condition of long period of functioning of NS.

In order to improve the quality of cable products, the idea of a multi-level system of structural and parametric identification of objects of the electrical complex of the technological line for the production of domestic cable with polymeric insulation on ultrahigh voltage is aimed at the main task. Systems guarantee correct, optimal for the main indicator of the quality of the solution of the problem under real conditions of structural, parametric and signal uncertainty and space-time limited data.

New methods have been developed for sample preparation and analysis of heavy metal ions in water based on polarography, which provide an accuracy of 2-6 orders of magnitude higher than those known today. Methods for determining trace concentrations of heavy metal ions in water have been developed. New processes of separation and removal of ions of heavy metals, chromates and other anions from acidic and alkaline solutions have been studied and developed to produce metals and chemical reagents suitable for reuse.

The novel technology was developed of heat transfer, gasdynamics, and film cooling efficiency prediction of high-performance gas turbine blades providing high accuracy of calculations.This technology takes into consideration stationary conditions and rotation of of cooled surface, blowing ratio, external flow speed, surface geometric shape (flat, concave, or convex), surface indentations configuration (spherical or rectangular), multi-row of coolant supply.

A universal gas diesel fuel supply system with microprocessor control (MPSS) for the conversion of diesels of stationary and transport facilities of average power, including military engines, to work on the gas-diesel cycle, which allows to improve the energy and environmental performance of the engine, reduce the consumption of diesel engines more expensive diesel fuel and attract cheap fuel for environmentally friendly gas to the fuel fund.

The experimental curves of the creep and the long-term strength of 25Kh1M1FA steel have been scientifically substantiated and proved by studying of the rotor of power unit No. 9 on the Luganskaya TES which had worked 275 thousand hours and reproduced all aging processes for the entire period of operation. The experimental curve of the long-term strength is supplemented taking into account the creep, which was limited a range of 175 thousands hours, up to 375 thousands hours.

A set of hardware and software for constructing distributed multi-channel microcontroller acquisition systems and processing of measurement information based on virtual measuring network networks supporting IP protocol, common digital interfaces, specialized CoAP/CoRE network protocols and flexible software configuration of measuring channels in a multitask environment is developed.
