Jovian Capture of a Spacecraft with a Self-Balanced Electrodynamic Bare Tether

摘要

This paper proposes and analyzes the use of a nonrotating tethered system for a direct capture in Jovian orbit usingudthe electrodynamic force generated along the cable. A detailed dynamical model is developed showing a strongudgravitational and electrodynamic coupling between the center of mass and the attitude motions. This paper shows the feasibility of a direct capture in Jovian orbit of a rigid tethered system preventing the tether from rotating. Additional mechanical–thermal requirements are explored, and preliminary operational limits are defined to complete the maneuver. In particular, to ensure that the system remains nonrotating, a nominal attitude profile for a self-balanced electrodynamic tether is proposed, as well as a simple feedback control.
