- investigation of distribution and interaction of impact and detonation waves at microscales;
- digital and experimental investigation of flow stability and laminar-turbulent transition at hypersonic speeds, as well as investigation of flow control possibilities using porous coatings and local heating will enable the project team to determine the fundamental physical laws for the following:
• Traditional and advanced jet propulsion technologies, including chemical and electrical rocket engines;
• Gas and multiphase currents in microscale devices and microscale nozzles;
• Aerothermodynamics of promising space vehicles;
• Development of instability and laminar-turbulent transition in hypersonic flows and investigation of applied aerothermodynamic problems within these areas.
Anticipated results of the project:
The project will help obtain digital and experimental data about the parameters of non-equilibrium flows in nozzles and streams, determine the fundamental mechanisms controlling distribution of impact and detonation waves at microscales, and examine the impact of viscosity and thermal loss on efficiency of microscale nozzles.
The project will help determine the aerothermodynamic parameters of various space vehicles operating within a broad range of altitudes and examine possibilities for control over laminar-turbulent transition using porous sound-absorbing coatings and local heating of surfaces.
The project team will put together recommendations on possible methods of deferring laminar-turbulent transition in practical conditions.
The project will help obtain information on how real gas affects the process of generation and development of excitations within a viscous shock layer on a plate, as well as investigate possibilities for exercising control over development of excitations.

The leading scientist made an important contribution to the development of digital methods of non-equilibrium gas dynamics, as well as a broad spectrum of fundamental and applied problems using the previously developed methods.
He conducted fundamental research of the nature of radiometric forces and their applications in microelectromechanic systems and propulsion engines. He was the first to experimentally confirm negative thermophoresis. He was the first to conduct kinetic research of rocket engines operating on the basis of inverted magnetic field. He was the first to conduct numerical research demonstrating how linear non-equilibrium affects laminar-turbulent transition.
He designed a kinetic multiphase computation system for high-precision modeling of solid propellant boosters.
