Title (EN) INDUCTION IGNITION DEVICE
(FR) DISPOSITIF DE MISE A FEU PAR INDUCTION
Abstract:
(EN) A device (2) for igniting a munition consisting of a projectile (4) and its propelling charge (5), comprising a breech (13) that is suitable for coming into contact with a chamber (6) of a barrel (1) loaded with said munition, said breech (13) closing said barrel (1) in the firing position, in which said breech (13) comprises a magnetic (7) or electromagnetic induction priming device allowing the combustion of the propelling charge (5) to be triggered and the projectile (4) to be fired from said barrel (1), a shield (3) positioned between the induction priming device (7) and the chamber (6) of said barrel, comprising a ceramic material made of an oxide, of a carbide, of a nitride, of an oxynitride or of a boride of at least one element chosen from silicon, aluminum, zirconium, boron, titanium, tungsten and hafnium, said ceramic material comprising grains, the maximum diameter of which is smaller than or equal to 500 micrometers, the shield being a right cylinder having a circular base.
(FR) Dispositif de mise à feu (2) d'une munition constituée par un projectile (4) et sa charge propulsive (5), comprenant une culasse (13) adaptée pour venir au contact d'une chambre (6) d'un canon (1) chargé de ladite munition, ladite culasse (13) fermant ledit canon (1) en position de tir, dans lequel ladite culasse (13) comprend un dispositif d'amorçage par induction magnétique (7) ou électromagnétique permettant de déclencher la combustion de la charge propulsive (5) et l'expulsion du projectile (4) dudit canon (1), un bouclier (3) disposé entre le dispositif d'amorçage par induction (7) et la chambre(6) dudit canon, comprenant un matériau céramique fait d'un oxyde, d'un carbure, d'un nitrure, d'un oxynitrure ou d'un borure d'au moins un élément choisi parmi le silicium, l'aluminium, le zirconium, le bore, le titane, le tungstène, l'hafnium, ledit matériau céramique comprenant des grains dont le diamètre maximal est inférieur ou égal à 500 micromètres le bouclier étant un cylindre droit de base circulaire.
