CA 2179373

A spin-stabilized projectile containing a payload is presented. The projectile includes a projectile body with a payload chamber that may be laterally defined by a projectile casing, on top by an axial fixing device for a payload disposed in the payload chamber, and on the bottom, by a dividing wall. The projectile casing may include axial grooves on the inside, which on the contribute to the fixing of the payload and include intended break zones for freeing the payload. Below the dividing wall, an opening charge may be disposed, which includes complete radial contact and is axially spaced apart from the dividing wall by a damping device. The detonation of opening charge causes the projectile casing to immediately split open at the intended break zones to release, by centrifugal force, the payload from the payload chamber. The damping device prevents the payload from being damaged in the region of the dividing wall and prevents the release of the payload from being interrupted.

L'invention porte sur un projectile stabilisé par rotation qui contient une charge transportée. Le projectile comprend un corps avec une chambre pour la charge transportée, qui peut être défini latéralement par une enveloppe, dans sa partie supérieure par un dispositif de fixation axiale pour la charge transportée placée dans la chambre, et dans sa partie inférieure par une cloison de séparation. L'enveloppe du projectile peut comporter des rainures axiales à l'intérieur qui contribuent à la fixation de la charge axiale et comprennent des zones de rupture à crans pour libérer la charge transportée. Sous la cloison de séparation, on peut placer une charge d'ouverture qui comporte un contact radial complet et est espacée axialement de la cloison de séparation par un dispositif amortisseur. La détonation de la charge d'ouverture provoque immédiatement l'ouverture en deux de l'enveloppe du projectile le long des zones de ruptures à crans et permet de libérer, sous l'action de la force centrifuge, la charge transportée de sa chambre. Le dispositif amortisseur empêche l'endommagement de la charge transportée à proximité de la cloison de séparation et empêche l'interruption de la libération de la charge transportée.
