In the course of work on the basis of the developed theory of interactive methods of control of formation of a difficult surface: by placement of an initial surface by means of functional dependences of geometry of a surface and parameters of space, the software integrating with CAD / CAM systems, namely the COPTeR software for space management is developed.
The fundamentals of non-trivial additive technologies of 3D-printing and cold spraying (CS) for the manufacture of complex-shaped products from cermet and ceramic composites, as well as from multicomponent metal alloys, which are fundamentally different from existing analogs of costly foundry methods ensure the level of material properties required for their operation at temperatures above 600 °C, under conditions of high-speed multiple heating-cooling (1500 deg/min), cyclic loading and in an aggressive oxidizing environment.
Algorithmic and technological approaches to the technological-constructive and algorithmic-software integration of the complex of navigation-visual modules and sensors are determined. A patent information study was carried out on a number of technical and technological solutions. A physical and mathematical model for solving navigation problems with the structure of a local navigation positional system has been developed. Optimal design parameters and operating modes of robotic platforms for a local navigation system have been developed.
A new approach to the creation of composite wear-resistant coatings is proposed, which consists in realizing the advantages of combining the effect of mechanical nanocrystallization and mechanochemical reactions in the near-surface layers treated with ultrasonic impact treatment (UIT) in chemically active and inert media. This fundamentally distinguishes the proposed technique from the known methods of synthesis of bulk composite materials and provides more effective, compared to heat treatment and standard UIT schemes, surface hardening.
Obtained ecologically safe compounds (organic compounds from plant extracts) for the formation of a passivation layer and modification of metal surfaces that meet global trends in the concept of sustainable development of "green" chemistry and "green" economy for enterprises.
The regularity of the formation of framework materials in the LaB6-TiB2-Cu systems was Regularities of formation of frame materials in the LaB6-TiB2-Cu system are established. Establishing the influence of technological parameters of the production process in the conditions of spark-plasma sintering and surface modification of ceramic reinforced particles on the structure, mechanical and electrical properties of the refractory frame. Spark-plasma sintering by temperatures of 850 ° C-1100 ° C was obtained composites (LaB6-TiB2) -Cu, with a content of refractory compound 2.5-70 vol.%.
The main threat for increase of the Ukraine’s mobilization potential is global tendence of liberalizetion of civil-military relations. The state structures should control the population to provide the mobilization activities. Unfortunately, it is not relevant to contemporary situation in Ukraine. The most of Ukrainian youth is not ready to protect its homeland or take part in other forms of defence.
Methods of water pre-treatment before baromembrane installations in order to remove the predominant amount of salts are proposed. The technological scheme of obtaining high-quality permiate in the amount of 90-95% of the initial volume of water during its preliminary stabilization treatment has been developed. The influence of various factors on the quality and yield of permiate has been established.
This paper investigates ways to increase the efficiency of coherent optical spectrum analyzers (COSA). The increase in efficiency is achieved through usage of space-time discrete light modulator in the COSA input and through recording of the spatial spectrum with a matrix detector (MD). The matching of the parameters of the modulator, Fourier lens and MD allowed to improve the technical characteristics of COSA. The matching means the choice of parameters of COSA’s components, which allow to obtain improved characteristics of the COSA.
