摘要

This paper provides a structural evaluation for electrodynamic tape tethers that can resist collisions with small items of space debris. To actively remove space debris such as defunct satellites from orbit, an electrodynamic tether that exploits the interaction between the geomagnetic flux and plasma electrons has been proposed. Among various types of tether, the large width and surface area of tape-shaped designs can resist critical impacts with small items of debris and collect many electrons from plasma space, resulting in successful removal missions. The survival possibility of tether systems in orbital paths evaluates the likelihood of a successful removal mission. In this paper, the relationship between the structural geometries of tape tethers and the impact hole caused by debris impacts is analyzed through large-scale hypervelocity impact experiments. A damage evaluation method based on stress concentration at the impact hole is then proposed to formulate the survivability of tape tethers. Finally, this paper evaluates the survivability of bare tape tethers, enabling comprehensive design guidelines to be identified for improving the survivability. An overall insight into electrodynamic tape tethers should be used for their detailed structural design.
