A bare electro-dynamic tape tether is expected to be employed in a sounding rocket project. Experiment is performed with S520-25 rocket which is donated by JAXA in 2009 summer. The tape tether is stored in a box in a foldaway storage method, which is a new concept of tether deployment schemes. The main theme of the present paper includes a numerical simulation on the separation of two payloads, an experimental study on the relationship between deployment velocity and deployment drag, on-ground experiments. The time history of the deployment velocity at the actual payload separation is designed with using the numerical simulation. The experimental results will be presented for the tape tether deployment employed with a water rocket model and also the concept of vacuum experiments on the tape tether deployment. The whole system in the project is also under synthesized and some experimental verification is addressed including the ejection system and braking scheme for the tape tether deployment.
