A projectile firing weapon (10) for firing artillery rounds (30) from a barrel assembly (11) utilises rounds having a projectile (31) and an associated bore seal (32) which is radially expanded by relative axial displacement between the projectile and the bore seal. The barrel assembly (11) provides a barrel bore (13), a barrel chamber (14) for the round to be fired and an associated breech chamber (15) for the next round to be fired. A propellant chamber (17) is formed between the barrel chamber (14) and the breech chamber (15). The breeched round (30) provides the closure for the barrel chamber (14) and after firing is advanced into the barrel chamber (17) by the next round introduced to the breech chamber (15). Liquid propellant may be injected to the propellant chamber (17) to facilitate rapid firing.
Arme à projectiles (10) conçue pour tirer des munitions d'artillerie (30) à partir d'un ensemble canon (11); dans cette arme on utilise des munitions qui comprennent un projectile (31) et un joint d'âme correspondant (32); ce dernier se dilate radialement sous l'effet du déplacement axial du projectile par rapport au joint d'âme. L'ensemble canon (11) comprend une âme (13), une chambre de canon (14), destinée à la munition à tirer, et une chambre de culasse (15), destinée à la munition suivante. Une chambre pour charge propulsive (17) est formée entre la chambre de canon (14) et la chambre de culasse (15). La munition introduite dans la culasse (30) obture la chambre de canon (14) et après le tir, elle est avancée dans la chambre de canon (14) par la munition suivante introduite dans la chambre de culasse (15). Pour faciliter le tir rapide, on peut injecter une charge propulsive liquide dans la chambre pour charge propulsive (17).
