Rarefied Gas Effects on the Magnetic Flow Control System for Aerobraking Flight of the Reentry Vehicle

Description

The impact of the rarefied gas effects on the applicability of the electromagnetic flow control system for aerobraking flight of the reentry vehicle is investigated by trajectory analyses. The numerical results suggest that even if the rarefied gas effects are considered the electromagnetic flow control system can still reduce the flight time of the aerobraking flight. This is due to that the vehicle is decelerated near the perigee point effectively by the imposed magnetic field, compared to the typical aerobraking flight vehicle. By utilizing this system, the flight time of the aerobraking flight can be reduced to about 50% of the flight time without imposed magnetic field.
