Abstract
Ensemble séparable par découpe pyrotechnique L’invention concerne un ensemble séparable par découpe pyrotechnique (1), comprenant une structure à découper (110), un élément de maintien (120) et un cordeau détonant (130), ledit ensemble (1) étant caractérisé en ce que le cordeau détonant (130) présente une section oblongue dont l’axe de symétrie de plus petite longueur (a) s’étend entre une première surface allongée (131) et une deuxième surface allongée (132) dudit cordeau détonant (130), le cordeau détonant (130) étant disposé dans une cavité formée entre la structure à découper (110) et l’élément de maintien (120) de sorte à ce que la première surface allongée (131) du cordeau détonant (130) soit maintenue en contact avec la structure à découper (110) et que la deuxième surface allongée (132) du cordeau détonant (130) soit maintenue en contact avec l’élément de maintien (120). Figure pour l’abrégé : Fig. 1Assembly separable by pyrotechnic cutting The invention relates to an assembly separable by pyrotechnic cutting (1), comprising a structure to be cut (110), a holding element (120) and a detonating cord (130), said assembly (1) being characterized in that the detonating cord (130) has an oblong section whose axis of symmetry of shortest length (a) extends between a first elongated surface (131) and a second elongated surface (132) of said detonating cord (130). ), the detonating cord (130) being arranged in a cavity formed between the structure to be cut (110) and the holding element (120) so that the first elongated surface (131) of the detonating cord (130) is maintained in contact with the structure to be cut (110) and that the second elongated surface (132) of the detonating cord (130) is maintained in contact with the holding element (120). Figure for abstract: Fig. 1
