Abstract
La présente invention concerne les dispositifs pour stocker, grâce à un ressort composite, de grandes énergies élastiques sous une faible masse, pour les applications suivantes : Dans le domaine de l’astronautique, de l’aéronautique, exemple séparation d’étages de fusée ; éjection : des boosters, de la coiffe ou de satellites. Dans le domaine des éléments élastique de suspension destinés aux transports. La présente invention a pour but de réaliser un dispositif, tolérant aux dommages, offrant une immunité au fluage, aux chocs à la corrosion et à l’entaille tout en atteignant des niveaux de densité d’énergie considérable à savoir 1 550 J/kg ! Ce niveau de performance est à comparer avec les modestes 300 J/kg des ressorts en acier ! La présente invention se caractérise par la forme dite en oméga, de son élément élastique de compression ; cette forme est dessinée à base de portion(s) d’ellipse(s), comme le montre la Figure 1, elle est terminée, préférentiellement, par des portions de boucles de fixation d’axe géométrique 4 et 6.
