| Research Abstract |
Result of a systematic study is reported on dynamic characteristics to play an important role in practical implementation of tether technology and synthesized in a category as "Experimental Study of Space Tether Technology on Actuator Performance".
The present systematic study includes a fundamental study on such tether system dynamics in micro-gravity condition as deployment and braking states. The study includes both numerical and experimental analysis and much important dynamic feature becomes apparent even for very fast deployment and nonlinear behavior of tether.
Based on these results an actuator and a velocity-tension sensor are studied for tether in order to verify technology of actuator of tether technology. A flexible-leverage actuator and a non-contact velocity-tension sensor are invented to employ in the tether control system and studied experimentally as a space tether technology on actuator performance.
Overall control performance is also studied with a solar power satellite orbiting in a moon orbit an example and result of the study shows an excellent performance.
Results are presented as many reviewed papers and presentations in international conferences and five patents are produced in the present study.
