Title
(EN) ARTILLERY SHELL PROPELLANT GAS SEALING DEVICE
(FR) DISPOSITIF D'ETANCHEITE AUX GAZ DE PROPULSION POUR MUNITIONS D'ARTILLERIE
Abstract
(EN)
A propellant gas sealing device for artillery shells comprising a projectile and a propellant charge, including a piston (10) attached to the back of the projectile by a separable connector (12) to separate the projectile from the explosive charge, a low pressure seal (14) supported by the piston for sealing the piston from the weapon chamber, and a high pressure plug (17) supported by the piston (10) for sealing the piston from the weapon barrel. The device is suitable for shells in which the propellant charge is separate from the projectile.
(FR)
Etanchéité au gaz de propulsion pour munitions d'artillerie. Le dispositif d'étanchéité aux gaz de propulsion pour munitions d'artillerie comportant un projectile et une charge propulsive est caractérisé en ce qu'il comprend: un piston (10) fixé à l'arrière du projectile par un dispositif de liaison séparable (12), piston isolant le projectile de la charge explosive, une garniture d'étanchéité (14) basse pression portée par le piston et destinée à assurer l'étanchéité entre le piston et la chambre de l'arme, et un obturateur (17) haute pression porté par le piston (10) et destiné à assurer l'étanchéité entre le piston et le tube de l'arme. Application aux munitions à charge propulsive indépendante du projectile.
