A numerical and experimental research of supersonic and hypersonic air flow round cubic fragments, differently oriented relative to the direction of the incoming flow was carried out. The results of visualizing supersonic airflow round cubic fragments are rendered by two methods: a theoretical one, based on a mathematical model by way of numerical solution of the Reynolds - averaged complete Navier-Stokes equations, and an experimental one using shadowgraphy.
