ON THE WEB-SITE ARE REPORTS OF WORKS IN "KPI" to priority areas of science and technology:
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.
There are done improved development and modeling, manufacturing and research of subsystems - power supply, navigation and orientation with a flywheel - electromagnetic executing mechanism and sensors for determining the coordinates of the Sun, high-speed radio communication and telemetry, an optoelectronic scanner, control and data processing - a flight model of a nanosatellite (NS) PolyITAN-3 -PUT 3U CubeSat format for remote sensing of the Earth. Including were:
1. Manufactured and tested:
- design of the case and solar panels for power supply (EPP) NS,
The gasification method with the highest value of the syngas calorific value and the prototype of equipment for calcining carbon-containing bulk material are substantiated. A mathematical model of the process of gasification of bulk carbon containing material in a drum-cooler of a rotary kiln was developed, based on a continuous-discrete formulation of the interaction of a mixture of reacting gases with a discrete solid phase, taking into account the turbulent flow regime and thermal radiation.
As a result of the work, a new technology for the production of intelligent polymer composite materials using sensors that provide the ability to obtain a sufficient level of information about the state of the polymer composition and products from them to manufacture on their basis responsible structural products.
