Field of research – fundamental research on the mechanics of the interaction of a solid body with plasma flows, electromagnetic radiation, electric and magnetic fields in the atmosphere and in the Earth’s ionosphere.

Research methods – physical and numerical modeling of processes and phenomena characteristic of the interaction of a solid body (aircraft) with the surrounding environment in the Earth’s atmosphere.

A brief research history in the department

Department 4 – Department of Aerogas Dynamics of the Dnipropetrovsk branch of the Institute of Mechanics of the Academy of Sciences of the Ukrainian SSR was organized on June 10, 1966. The first head of the department was the Hero of Socialist Labor, corresponding member of the Academy of Sciences of the USSR and Academy of Sciences of the Ukrainian SSR, member of the International Academy of Astronautics, Doctor of Technical Sciences, Professor, laureate of the Lenin and State Prizes of the USSR, chief designer of KB-3 V. M. Kovtunenko.

In 1973, a laboratory of ionospheric aerodynamics was organized in the department, on the basis of which in 1987 the department of mechanics of ionized media of the Institute of Technical Mechanics of the Academy of Sciences of the Ukrainian SSR was created. Doctor of Technical Sciences, Professor V. O. Shuvalov became the head of the department.

The department is one of the world leaders in research in the field of “mechanics of the interaction of a solid body with plasma flows, electromagnetic radiation, electric and magnetic fields in the atmosphere and in the Earth’s ionosphere.”

According to the research results in the department, the following have been scientifically substantiated:

  • the effectiveness of plasma countermeasures to radar detection and recognition of aircraft (AC) in the upper layers of the Earth’s atmosphere, distortion of radar characteristics, reduction of the visibility of aircraft in the Earth’s atmosphere (“plasma-stealth” technology in the centimeter, decimeter and meter wavelength ranges).

The effectiveness of plasma countermeasures for radar detection and recognition of aircraft signatures has been confirmed in live experiments on space vehicles (SC) of the “Cosmos” series and the “Altitude Atmospheric Probe” spacecraft;

Distortion of backscatter diagrams
of various spacecraft models
  • procedures have been developed to forecast the degradation of the electrical power of silicon solar batteries of space vehicles under the conditions of long-term action (within 10-15 years) of a complex of space factors in near-Earth circular, highly elliptical and geostationary orbits, namely: atomic oxygen, ionizing and ultraviolet radiation, contamination of protective surfaces, thermal cycling, radiation electrification, plasma jets of electrojet engines;
  • development and creation of scientific and scientific-technological equipment for spacecraft.

On-board system of active ion-plasma protection of spacecraft against the consequences of high-voltage differential electrification

The most important achievements of the department

A set of on-board scientific equipment for diagnosing ionospheric plasma has been developed – sensors of charged and neutral particles (electric cylindrical Langmuir probes, two-channel electric pressure probe). The equipment has been installed and operated on the Ukrainian space vehicles “Sich-2”, “Sich-2-30”. The equipment makes it possible to identify the localization of sources of ionospheric plasma disturbances caused by natural phenomena, man-made disasters and seismic activity on subsatellite tracks.

Within the framework of the international project RP 7 of the EU “Improving the safety of low Earth orbit using an improved electric rocket engine” (“LEOSWEEP” project FP7-SPA 2013.3.2-01, EUROPEAN COMMISSION 7th Framework Program for Research, technological, Development and Demonstration, concluded under the results of the victory in the FP7-SPACE-2013 competition of the European Union) to justify active methods and means of removing large fragments of space debris using intense ion and plasma jets, models of dynamic interaction of high-energy ions of plasma flows with structural materials of rocket and space technology products have been determined: the dependence of coefficients has been determined sputtering, momentum and energy accommodation coefficients from the type and kinetic energy of ions, from contact angles with the surface of materials, taking into account secondary emission and particle reflection.

Current cooperation

A number of works and studies have been carried out and are conducted in cooperation with leading institutions of the aerospace industry, universities and academic institutes: State enterprise “M. K. Yangel “Yuzhnoye” Design Office, Lviv Center of the Institute of Space Research of the National Academy of Sciences of Ukraine and the Institute of Space Research of the National Academy of Sciences of Ukraine, Oles Honchar Dnipro National University, Ukrainian State University of Chemistry and Technology and others.

Experimental base

Experimental research is carried out on the ITM plasma-electrodynamic stand developed and created in the department, which was included in the State Register of scientific objects that are national property by Order of the Cabinet of Ministers of Ukraine dated August 28, 2013 No. 650.

ITM plasmodynamic bench

The stand is intended for the study of various aspects of the interaction of a solid body (including materials and structural elements of aircraft) with the environment in the Earth’s ionosphere and magnetosphere.
