With results of testing various models for several last years, the article will describe the capabilities of the IT-302M hotshot wind tunnel in terms of modeling of high-velocity flows in the Mach number range from 4 to 20 for external flow regimes and from 2 to 6 for the attached pipeline regime with the following flow parameters: total pressure from 5 to 1000 bar and total temperature from 700 to 3500 K. Some of these pioneering activities are unique: for instance, a positive thrust force was obtained in a scramjet model for the first time; a series of tests was performed for comparisons of the results of inlet flows obtained in hotshot and blow down wind tunnels, including shock starting of the inlet and a possibility of its modeling by using a special device in the long-duration wind tunnel. A new concept of a short-duration wind tunnel with opposing pistons of pressure multipliers has been considered.
