Design of Brake Control System on Sounding Rocket Experiment

Abstract

One engineering experiment and two scientific experiments are scheduled by using the bare electro-dynamic tape tether on the S520 sounding rocket in 2009. Purpose of the engineering experiment is a quick deployment of tape tether stored in the box with the foldaway storage method, which is a new concept of tether deployment schemes. The design of braking control system for foldaway tape tether deployer is studied in this paper. Braking drag force is measured by experiment in vacuum condition and air, and braking drag characteristic is analyzed from these results of several kinds of experiments.
