Abstract

L'invention concerne un projectile d'exercice de gros calibre (1) comportant une partie ogive (3) massive et un corps d'empennage (5) tubulaire dans le prolongement arrière de la partie ogive (3). L'invention vise à assurer la résistance au tir de ce projectile de manière économique. A cet effet, le corps d'empennage (5) est conçu de sorte que les gaz de charge propulsive dégagés lors du tir du projectile d'exercice (1) agissent également sur la face externe (6) de la paroi latérale (7) du corps d'empennage (5) tubulaire. Afin d'éviter que les gaz de charge propulsive ne s'écoulent sur la face externe du projectile d'exercice (1) à l'intérieur du canon de l'arme, un système d'étanchéité (10) est prévu dans la zone de la partie ogive (3) massive du projectile d'exercice (1), ce système comprenant une bague d'étanchéité (11) soumise à l'action d'une bague conique (12). La bague conique (12) axialement mobile et la bague d'étanchéité (11) sont toutes deux disposées dans une rainure annulaire (13) ménagée dans la zone arrière de la partie ogive (3). La bague d'étanchéité (11) disposée devant la bague conique (12) dans la direction de tir du projectile d'exercice (1) présente une cavité interne (14) arrière en forme de cône dans laquelle s'emboîte à force et par liaison de forme la partie avant de la bague conique (12) de sorte que, lorsque la bague conique (12) est soumise à une pression axiale, elle est déplacée dans l'axe et appuie la zone de paroi latérale (15) externe, qui agit comme lèvre d'étanchéité, de la cavité interne (14) en forme de cône de la bague d'étanchéité (11) radialement contre la paroi interne du canon de l'arme.
