Abstract

L'invention a pour objet un projectile incorporant un générateur d'éclats (1) comprenant une enveloppe perforante (2) renfermant un matériau élargisseur (3) capable sous la pression due à la perforation d'accélérer radialement le matériau de l'enveloppe (2), l'enveloppe perforante (2) étant fermée à sa partie avant par un piston (4) solidaire de l'enveloppe (2), piston comportant une face arrière (5) appliquée contre le matériau élargisseur (3) et une partie externe à l'enveloppe qui porte une surface partiellement sphérique (6). Ce projectile est caractérisé en ce que le générateur d'éclats (1) est sous calibré et disposé à l'intérieur d'un corps (13) de projectile (8), le générateur d'éclats (1) étant rendu solidaire du corps de projectile par un moyen de liaison, le corps (13) de projectile comportant des amorces de rupture (23) ou des fragilisations longitudinales favorisant son ouverture à l'impact sur une cible et la libération du générateur d'éclats (1).

Figure imgaf001
The invention relates to a projectile incorporating a splinter generator (1) comprising a perforating envelope (2) enclosing a widening material (3) capable under pressure due to the perforation of accelerating radially the material of the envelope ( 2), the perforating envelope (2) being closed at its front portion by a piston (4) integral with the casing (2), a piston having a rear face (5) applied against the expanding material (3) and a part external to the envelope which carries a partially spherical surface (6). This projectile is characterized in that the chip generator (1) is sub-calibrated and disposed inside a projectile body (13) (8), the fragment generator (1) being secured to the body projectile means by means of a connection means, the projectile body (13) comprising rupture initiators (23) or longitudinal weakenings favoring its opening on impact on a target and the release of the chip generator (1).
