Title
(EN) Deployable KiriForm Flexures
Abstract
(EN)

A deployable Kiriform flexure includes first and second sections. The first section of the Kiriform flexure includes a plurality of curved fins arranged about a central axis. The second section of the Kiriform flexure includes a plurality of curved fins arranged about a central axis. Each fin of the second section is joined with a fin of the first section such that the first and second sections share a common central axis in a configuration that produces out-of-plane elastic buckling of the fins to actuate the Kiriform flexure from a substantially flat structure that extends substantially only in two dimensions orthogonal to the central axis to an expanded structure extending substantially in a third dimension parallel to the central axis when at least one of the first and second sections is rotated relative to the other section.
