通过弹道分析和DSMC仿真，对电磁气动制动飞行系统的适用性进行了研究。数值结果表明，在较弱的外加磁场条件下，电磁流量控制系统能大幅度缩短航空制动飞行的飞行时间。这是由于与空气动力相比，电磁力在近地点附近更有效地降低了飞行器的速度。利用该系统可将航空制动飞行时间缩短至无外加磁场飞行时间的30%左右。
The applicability of the electromagnetic aerobraking flight system is investigated by using trajectory analyses and DSMC simulations. The numerical results indicate that the electromagnetic flow control system could shorten the flight time of the aerobraking flight drastically with a relatively weak applied magnetic field. This is due to that the vehicle is decerelated near the perigee point more efficiently by the electromagnetic force, compared to the aerodynamic force. By utilizing this system, the flight time of the aerobraking flight could be reduced to about 30% of the flight time without applied magnetic field.
