CFRP Tethers for Use in Multi-Directional Tether Deployment Mechanisms

We examined the tether storage method and extension method that are useful for multi-directional deployment of CFRP space tethers for space deployment structure. Tether stretching experiments were performed in a simulated weightless environment using CFRP tethers of different cross-sectional properties. It has become clear that stable attitude can be developed stably by devising the storage method. We are also developing an automatic extension device by sending commands.
