  • Effects of applied magnetic field on IPG6-S, test-bed for an ABEP-based inductive plasma thruster (IPT) 

    Romano, Francesco; Herdrich, Georg; Binder, Tilman; García-Almiñana, Daniel; Rodríguez Donaire, Silvia; Sureda Anfres, Miquel (Association Aéronautique et Astronautique de France, 2018)
    Conference report
    Restricted access - publisher's policy
    An atmosphere-breathing electric propulsion system (ABEP) captures the residual atmosphere of a planet and uses it as propellant for an electric thruster to counteract the drag. The system would theoretically allow orbiting ...
