【 摘 要 】

This article presents the results of mathematical modeling of the interaction of a single supersonic jet with a wedge barrier. The angles of the wedge were 0, 5, and 10 degrees. The distance from the nozzle to the barrier was 0.5 meters. The parameters of the gas of hydrazine combustion products at the nozzle inlet varied. Mach number at the nozzle exit was 4 and 5. It was found that the wedge angle of the barrier slightly affects the shape of the jet, the shape of the wall jets and the pressure along the barrier at an ambient pressure of 650 Pa and a temperature of 250 K. With an increase in the barrier angle, the pressure on the jet axis decreases and the first barrel of the wall jet is displaced.
