Title
(EN) DEPLOYABLE KIRIFORM FLEXURES
(FR) FLEXIONS DE KIRIFORM DÉPLOYABLES
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.
(FR)
La présente invention concerne une flexion de Kiriform déployable qui comprend des première et deuxième sections. La première section de la flexion de Kiriform comprend une pluralité d’ailettes incurvées agencées autour d’un axe central. La deuxième section de la flexion de Kiriform comprend une pluralité d’ailettes incurvées agencées autour d’un axe central. Chaque ailette de la deuxième section est assemblée à une ailette de la première section de sorte que les première et deuxième sections partagent un axe central commun dans une configuration qui produit un flambage élastique hors du plan des ailettes de façon à actionner la flexion de Kiriform d’une structure sensiblement plate qui s’étend sensiblement uniquement dans deux dimensions orthogonales à l’axe central à une structure étendue s’étendant sensiblement dans une troisième dimension parallèle à l’axe central lorsqu’au moins l’une des première et deuxième sections est tournée par rapport à l’autre section.
