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.
