The institute provides scientific and technical support to the execution of the projects of the National Space Programs of Ukraine and coordinates R&D’s in space engineering under the supervision of the National Space Agency of Ukraine.
At present, fundamental and applied research are conducted at the institute. Those involve:
The institute has developed unique experimental and test facilities, software, and physical and mathematical models to study processes that take place during space hardware transportation to launch sites, orbital injection, operation in space, and re-entry. These scientific and technical developments contribute to bringing the Ukrainian space science and technology to the world’s level and even above it.
In content and the novelty of obtained results, these investigations are unparalleled. They have made it possible to gain a new insight into the LPRPS dynamic processes and to lay the scientific and technical foundations of a novel line of research in LPRPS and liquid-propellant launch vehicle dynamics..
Fundamental investigations have been conducted on the injection of inert and reactive liquids and gases into a supersonic high-enthalpy gas flow. The obtained results have made it possible to develop pioneer,radically new high-performance final control elements for the rocket flight control system..
A prominent place in the institute’s research area is occupied by launch vehicle, engine, and spacecraft aerogasdynamics and spacecraft-environment interaction in the Earth ionosphere and magneto-sphere. Numerical simulation methods have been developed for space vehicle aerogasdynamics in re-entry and in a flight at a high supersonic speed. A complex of effects and phenomena that characterize spacecraft-environment interaction in the Earth ionosphere and magnetosphere has been studied.
Investigations in the area of aerodynamic support of space R&D’s were started at the institute on the initiative of the former Chief Designer of Yuzhnoye Design Office’s Design Office No 3 (from 1986 Designer General of Lavochkin Research and Production Association) V.M. Kovtunenko, Corresponding Member of the Ukrainian and the Russian Academy of Sciences, who headed the aerogasdynamics department at the institute. At present, three research departments of the institute are engaged in continuation of aerodynamic investigations.
In the dynamics of mechanical systems, efficient methods of study of steady and unsteady oscillations of complex mechanical systems have been developed, and methods of identification and stabilization of their parameters have been proposed. Mathematical models and methods have been developed to provide safe rail transportation of space structures and to predict and minimize vibrational loading.
Methods have been developed for the analysis and synthesis of mobile control and the study of the dynamics of singularly perturbed mechanical systems.
Solutions have been found to the complex problems of deformation, strength, and carrying capacity (with the inclusion of the plasticity and creep of the material) of nonuniform structures of aerospace hardware, power equipment, and transport vehicles operating under intensive actions of complex physical nature, including local loads and contact interactions.
Efficient comprehensive methods have been devised to calculate the reliability and durability indices of space systems in designing, tryout, manufacturing, and operation. Probabilistic-statistical methods of complex engineering systems designing have been developed.
Methods have been developed for the techno-economic analysis of large systems with consideration for market uncertainties..
The obtained results have been widely used in space hardware development, and they significantly contributed to the successful commissioning and operation of the Zenit and Cyclone launch vehicles and the implementation of the Venus Halley international project and other projects. Some lines of research have gained international recognition: the study of hydrodynamic cavitation, including cavitation in liquid-propellant rocket engine pumps, space vehicle aero- and plasmadynamics, land-based vehicle statistical dynamics, etc..
Radically new pneumatic systems for driver vibroprotection have been developed and studied experimentally.A number of advanced proprietary technologies have also been created and found experimental proof-of-a-principle. Among them are a technology of cavitation pulse hydroabrasive treatment of metal surfaces; a technology of deposition of heat- and corrosion-resistant coatings onto engineering and metallurgical products; a technology for the manufacturing of high-strength thin-walled structures of antenna/waveguide devices, solar concentrators, and other complex-shaped elements; a technology of low-grade coal burning, etc.
The institute’s computing facilities are up-to-date, and its experimental facilities for the study of hydrodynamic processes in rocket propulsion feed systems and thermogas dynamic and heat-and-mass exchange processes in power plants, the simulation of high-, medium-, and low-altitude flight conditions, strength and vibration testing, and the tryout of electroforming-based radio device and solar concentrator manufacturing processes are unique.
The institute has an editorial and publishing system equipped with up-to-date facilities and publishes a scientific journal, “Tekhicheskaya Mekhanika” (“Technical Mechanics”).
The institute has numerous scientific and partner contacts in the field of space hardware development, rail transport, and mechanical and heat-power engineering with a large number of Ukrainian and foreign institutes, universities, enterprises, and organizations.
Based on the results of the studies conducted, 126 monographs, 64 collected volumes, and more than 5,687 papers have been published since the institute was established. 927 inventor’s certificates and patents have been issued. 34 D.Sc. and 207 PhD theses have been defended.
Institute scientists participate in many international societies and organizations, among which are the International Academy of Astronautics, the Tsiolkovsky Russian Academy of Cosmonautics, the American Society of Mechanical Engineers, the International Society for Air Breathing Engines, the German Society for Applied Mathematics and Mechanics, and International Engineering Academy.
