<p>An extendable structure (100) which may be used in space-based applications, for example forming the body of a telescope. The structure is movable between a stowed configuration and an extended configuration, and comprises a plurality of walls (401,402,403,404) arranged to give a polygonal cross-section in the extended configuration. Each wall comprises a plurality of repeating units (2501,2502) which are connected by a plurality of hinges. Each repeating unit itself comprises a plurality of sections (101,102,103,104,105,106) connected by a plurality of hinges (109,110,111,112,113,114). The plurality of hinges may comprise tape-spring hinges.</p> |
