The aim of the invention is to obtain great final ballistic effectiveness of fragmentation bullets and warheads regardless of the impact speed while using as little explosive material as possible. Said aim is achieved by combining an explosive shell (3) with a damming inner member (4) in connection with an accelerated outer jacket (2). This arrangement results in the best possible conversion of the explosive energy while offering great creative flexibility regarding the design. A wide range of additional possible effects is created by blast-compacting the inner damming member (4). Furthermore, the shape of the inner damming member allows the fragments to obtain a directionally controlled effect. Depending on the caliber and technical design, the amount of explosive material used can be reduced by 50 to 80 percent compared to conventional explosive bullets at comparable fragment speeds or sub-bullet speeds. The explosive material economized is available as additional effective mass. The accelerated jacket (2) can also be entirely or partly composed of preformed fragments or sub-bullets.

L'objectif de cette invention est de créer des projectiles ou des ogives à fragmentation permettant d'obtenir une efficacité balistique finale élevée, indépendamment de la vitesse d'impact, avec le moins de matière explosive possible. A cet effet, une enveloppe en matière explosive (3) est combinée avec un corps d'isolation interne (4) et une enveloppe externe (2). Cette configuration permet de convertir l'énergie de la matière explosive de la meilleure manière possible, et offre en outre une grande liberté de conception. La compression du corps d'isolation interne (4) par la matière explosive permet de créer un large éventail de possibilités supplémentaires. La configuration de l'élément d'isolation interne permet de commander la direction des fragments. La quantité de matière explosive peut être réduite de 50 à 80 %, en fonction du calibre et de la conception technique, par rapport aux projectiles explosifs traditionnels, pour des vitesses comparables de fragments ou de sous-projectiles. La quantité de matière explosive économisée peut servir de matière active supplémentaire. L'enveloppe accélérée (2) peut aussi être totalement ou partiellement constituée de fragments préformés ou de sous-projectiles.
