Abstract: This Letter presents the results of an experimental and numerical study of a supersonic ($\mathbf{M}_\infty$ = 7) flow past a hollow cylinder with gas-permeable porous inserts, installed along the flow. We demonstrate that it is possible to control the aerodynamic drag of the model by transferring some of the free-stream flow into the base region through gas-permeable porous inserts. The flow rate of the air directed to the base region to control the drag was regulated by heating the porous inserts with an electric glow discharge.
Keywords: aerodynamic drag, control, porous materials.
