Abstract
In recent years, the research on flexible space structure is rapidly advanced in many country. One of the examples of the flexible space structure, the authors has been developing a nano-satellite named "SPROUT". The main mission of SPROUT is deployment demonstration of combined membrane structure by the inflatable tube. But, flexible space structure is difficult to experiment on the earth because air drag and gravity is very affected. So, we need know numerical analysis result of deployment dynamics. However, it is not enough data because the results of deployment demonstration on orbit are very few. So the purpose of this experiment, we establish the new estimation method of flexible space structure by ground experiment and microgravity experiment. We think the results of this experiment are big steps of realization of large scale of flexible space structure. In this paper, the author introduces the results of experiment and the new estimation method of flexible space structure by ground experiment results.
