One of possible effect of electromagnetic field on the high-speed ionized airflow is considered. Namely, deceleration of the flying body due to interaction of the electric current induced around the body with the magnetic field generated by on-board magnetic system is studied. The principal scheme of magnetohydrodynamic interaction over the flat plate is presented. The goal of the study is to demonstrate the deceleration effect in terms of standard aerodynamic drag. Two test cases are considered: small-scale (lab-scale) interaction zone size and large-scale (space-scale) one. The primary result of the study is a feasibility to increase the total drag of the body in more than order of magnitude relative to the original one. The effect can be achieved by means of practically reasonable magnetic field amplitudes. Common for both cases is that the total drag grows as the magnetic field increases. The difference between two cases is that significantly smaller magnetic fields are required in space-scale case to increase aerodynamic drag than in the lab-scale case. In any case, the drag control could be used as a potential for high-speed flow control.
