Title (EN) SACRIFICIAL BREAKAWAY MECHANISM
(FR) MÉCANISME DE RUPTURE SACRIFICIEL
Abstract:
(EN) A sacrificial breakaway mechanism (1) comprising: a first piece (5) attached to a fixed structure (3); a second piece (6); a plurality of connectors (11, 12) running between the second piece (6) and the fixed structure (3); and a sacrificial element (8) connecting the first piece (5) to the second piece (6), wherein said sacrificial element (8) is configured such that a tensile load exceeding a predetermined threshold exerted on the second piece causes the sacrificial element (8) to break, separating the first piece (5) from the second piece (6) and allowing relative movement therebetween, said relative movement causing a sequential disconnection of the plurality of connectors (11, 12).
(FR) Selon l'invention, un mécanisme de rupture sacrificiel (1) comprend: une première pièce (5) fixée à une structure fixe (3); une seconde pièce (6); une pluralité de raccords (11, 12) s'étendant entre la seconde pièce (6) et la structure fixe (3); et un élément sacrificiel (8) raccordant la première pièce (5) à la seconde pièce (6), ledit élément sacrificiel (8) étant conçu de sorte qu'un travail à la traction dépassant un seuil prédéterminé et exercé sur la seconde pièce provoque la rupture de l'élément sacrificiel (8), séparant ainsi la première pièce (5) de la seconde pièce (6) et permettant un mouvement relatif entre celles-ci, ledit mouvement relatif entraînant un découplage séquentiel de la pluralité de raccords (11,12).
