Abstract: Results of experimental studies and numerical calculations of aerodynamic characteristics of a supersonic flow around a body of revolution with a gas-permeable porous nose cone and an internal duct are presented. At a flow velocity corresponding to the Mach number $\mathrm{M}=3$, the body considered is found to have a lower drag coefficient (approximately by 9%) than a similar body impermeable for the gas and a lower streamwise static stability.

Keywords: cone-cylinder body of revolution, supersonic flow velocity, drag coefficient, gas-permeable porous surface, streamwise stability, aerodynamic tests.
