Abstract

Le canon d'arme à feu est constitué de plusieurs parties. Grâce à cette conception, la rigidité du canon augmente fortement alors que l'angle de sortie du projectile par rapport à l'axe du canon diminue sensiblement, ce qui augmente le précision du tir. Le canon est refroidi par un flux d'air ou grâce à un liquide. Lorsque le canon est soumis à un prétensionnement, un système rigide se crée entre le canon et la gaine, qui peut être considéré comme un corps relativement dur, l'angle de sortie du projectile par rapport à l'axe du canon dans ce système étant égal à zéro. L'invention permet d'augmenter sensiblement la précision du tir et mieux calculer la balistique du projectile.
