【 摘 要 】

The space vehicle deceleration at reentry into the atmosphere leads to aerodynamic heating and, hence, ionization of near-wall plasma layers. The plasma layer causes radio communication blackout. This report discusses the possibility to provide a blackout mitigation by changing the plasma parameters near the body with the help of the magnetohydrodynamic (MHD) effects. The numerical simulations were carried out for the conditions corresponding to those at the DLR test facility.
