Abstract (en)

[origin: US4714022A] A warhead designed for employment against a target having active armor protection comprises a forward shaped charge and a rear shaped charge. The forward shaped charge generates a core explosion whose speed is below 2,500 meters per second, and thus does not detonate the active armor, while the rear charge is formed of a high-performance, high-explosive charge and completely pierces the armor. A time delay of between 50 and 300 mu sec is employed for detonating the rear charge after the detonation of the first charge. This type of warhead is suitable for piercing rolled homogenous armor (RHA), or spaced, composite, or active armor, and can be fired by means of rockets, missiles, shells, etc.

Abstract (fr)

Le secteur technique de l'invention est celui des têtes militaires comportant plusieurs charges creuses. La tête militaire selon l'invention est constituée par une charge explosive formée (2) capable de générer un noyau dont la vitesse est inférieure à 2500 m/s de manière à ne pas faire détoner les blindages actifs, et une charge formée arrière (3) destinée à la perforation complète du blindage. Application à la perforation des blindages simple, feuilletés, composites ou actifs à l'aide de roquettes, missiles ou obus.
