A detonator which includes, inside a tubular housing two containers which are -breakable thereby to release their contents which, when mixed, form an ignitable explosive composition.
摘要:
An explosives detonator system for detonating an explosive charge with which it is, in use, arranged in a detonating relationship is provided. On acceptance of a detonation initiating signal having a detonation initiating property, the system initiates and thus detonates the explosive charge. The system includes an initiating device which accepts the detonation initiating signal and initiates and thus detonates the explosive charge. The initiating device is initially in a non-detonation initiating condition, in which it is not capable of accepting the detonation initiating signal. The system also includes a switching device that detects a chemical compositional component as a switching property of a switching signal that is transmitted to the detonator system, with the switching device being capable of switching the initiating device, on detection of the chemical compositional component, to a standby condition in which the initiating device accepts the detonation initiating signal when it is transmitted thereto.

L'Invention concerne un système mécanique d'auto-destruction d'une munition, en particulier d'une sous-munition d'obus cargo, la munition tant pourvue d'une charge militaire (4) initiée par une chaîne pyrotechnique (1) comprenant un percuteur principal (2) et un dispositif d'amorçage constitué d'un coulisseau (3) mobile entre une position de sécurité et une position d'armement, et qui porte un moyen d'amorçage (6) de la charge (4). Le système (10) comprend un percuteur secondaire (15) monté à l'intérieur d'un logement (5b) du coulisseau (5) et un dispositif de commande (16) pour libérer le percuteur secondaire (15) après un retard prédéterminé. Le percuteur secondaire (15), est solidaire d'un élément de retenue (25) maintenu en appui sur un siège (28) sous la sollicitation d'un ressort d'armement (26), le dispositif de commande (16) du percuteur secondaire (15) comprenant un agent corrosif (30) destiné à attaquer chimiquement l'élément de retenue (25) pour le libérer de son siège (28).

Method and device for mixing and initiating a pyrotechnic charge, comprising at least one coherent porous fuel structure (16) and at least one oxidizer (8). According to the invention, the coherent porous fuel structure (16) and the oxidizer (8) are placed apart in a mixing device (1, 20) to prevent unintentional ignition, and in which the oxidizer (8), in response to the action of a force upon the mixing device (1, 20), for example upon firing of an artillery shell, is transported into the coherent porous fuel structure (16), after which the obtained pyrotechnic charge is initiated after a set time delay.
摘要:
An apparatus for the generation of electricity that may be in a "standby" mode for long periods of time, i.e. many years. Thus, in one embodiment of the invention, a fuel cell may include at least one of the following features or components: a membrane, and/or storage tanks or cells for hydrogen and oxygen, and/or an "inertial" switch, which may optionally be assembled in close proximity to a membrane. The inertial switch, when activated, may rupture the membrane and allow the hydrogen and oxygen to mix in a fuel cell.

L'invention concerne un dispositif de sécurité pour engin explosif 1 du type mine roquette ou missile, lancé à partir d'un tube 38, comprenant un volet de sécurité 2 maintenu par un premier moyen de verrouillage 4 dont l'effacement est interdit par un moyen de blocage 8. Il comporte un second moyen de verrouillage 5 du volet 2, indexé sur le tube 3 et un moyen de verrouillage 5 coopérant avec le moyen de blocage 8, d'une part, et un ressort 12 à mémoire de forme dont le changement de caractéristiques mécaniques commande l'effacement du moyen de blocage 8. Le moyen de blocage 8 assure de plus le blocage du moyen de verrouillage intermédiaire 19, et son effacement est commandé par le ressort 12 à mémoire de forme autorisant la translation du moyen de verrouillage intermédiaire 19 et la libération du second moyen de verrouillage 8. Application aux projectiles.
