Mechanisms for deployable tensairity structures

This paper investigates suitable deployment mechanisms for Tensairity structures. Three proposals for a compression element for a deployable Tensairity structure are presented: the ‘spiral folding mechanism’ (segmented compression element), the ‘triangulated cylinder’ and the ‘foldable truss mechanism’. The concepts of the first two proposals are described and illustrated in the paper. The ‘foldable truss’ system is discussed more in detail.
