Abstract

Radio communication blackout is one of the most significant obstacles to the operation and telemetry of hypersonic vehicles. The plasma manipulation with a pulsed magnetic field has been identified as a promising solution to the blackout problem through laboratory observations. To evaluate the effect of the pulsed magnetic field in realistic hypersonic flight conditions, this work numerically studies pulsed magnetic field manipulation for the plasma layer of hypersonic vehicles based on the magnetohydrodynamic model coupled with the high-temperature gas effect. The Wentzel-Kramer-Brillouin (WKB) method is used to analyze the transmission characteristics of electromagnetic waves in a magnetized plasma. The numerical results show that the pulsed magnetic field with suitable pulse duration can reduce electron density and radio attenuation near the antenna. The communication window created by the pulsed magnetic field allows lower-frequency radio to transmit through the plasma layer and the duration of the window can last more than 0.1 ms. Besides, the effect of blackout mitigation by the pulsed magnetic field is significantly enhanced with increasing magnetic field strength at each flight altitude. These investigations can provide useful information for designing and optimizing electromagnetic manipulation for blackout mitigation.
