  • Descrição: We have experimentally studied the effect of a gas-permeable material situated in front of a blunt body on the aerodynamic drag of this system in a supersonic airflow with a Mach number of M = 4.85. It is established that the porous material significantly reduces the wave drag in the system. Explanation of the observed phenomenon is proposed.
