Definitions

  • the invention relates to a propellant cage with a missile, which is held in a propellant charge sleeve and has the features of the preamble of claim 1.
  • the invention has for its object to achieve a further increase in performance with simple means, as well as an increased firing resistance of the missile.
  • the Fig. Shows an embodiment of the new arrangement in side elevation after a longitudinal axis section.
  • the penetration performance of the missile against multi-plate targets is improved - even under difficult conditions.
  • the missile 10 is designed with a longitudinal axis 11 and with a center of gravity 17 in a transmission area 16 in a targeted manner; Incisions 16.1 to 16.5 provided as positive locking means are also designed as predetermined breaking points.
  • the pre-cores 19.1 to 19.4 formed by the predetermined breaking points Due to the transition cone, the pre-cores 19.1 to 19.4 formed by the predetermined breaking points have a larger diameter de than the diameter, ie the main core 14 ', and thus allow this unimpeded penetration through the penetration hole created by the pre-cores in the target.
  • the transition cone 15 is included in the transmission area 16.
  • the incisions 16.1 to 16.5 are assigned a respective smallest diameter de. They separate from one another a tip body 12 ', pre-cores 19.1 to 19.4 and an adjoining front part 14 "of the main core 14', the larger diameter being assigned to the pre-cores and the front part 14".
  • the new design of the ammunition unit results in increased performance through an increased load.
  • the transition cone as a rear extension achieves an advantageous degree of slenderness of the main core 14 '.
  • the pre-cores result in a targeted breakability, which prevents the main core from being deflected from the desired direction.
  • the mass available according to the invention for striking multi-plate targets is increased.
  • the inclusion of the transition cone 15 in the transmission area 16 achieves the increased firing resistance of the missile. Only then is it possible that only the incisions between the front cores can serve as form-locking means.
  • the propellant charge sleeve can be at least partially combustible.
  • the sabot 20 can be designed without radial projections (29) or ribs for additional holding on the sleeve, since due to the surging gas pressure also acting radially on the gas pressure receiving surface, a required positive connection between the missile 10 and the sabot 20 is ensured in the common transmission area 16.
  • the drive cage 20 is formed by a predeterminable number of segments 21 and has an essentially caliber-like part with a circular cylindrical circumferential surface 33, a front inflow surface 25 and a rear gas pressure receiving surface 27a.
  • the inflow surface 27a extends from a front end edge 26, which grips the tip 12 'of the missile 10 at a radial distance, to a rear edge 27, which closely surrounds the missile.

Claims (2)

1. Cage de propulsion (20) segmentable retenue dans une douille de charge propulsive dans sa zone antérieure, comportant une poche d'air antérieure qui entoure par des moyens d'accouplement à concordance de forme un projectile (10) à direction stabilisée de grand rapport lon- gueur/diamètre dans sa zone centrale commençant juste derrière la pointe (12') du projectile et qui comporte à l'arrière une surface de réception de pression gazeuse (27a) qui s'étend, sous la forme d'un profil fléchi, d'un bord extérieur de la cage situé juste derrière le point de fixation du sabot dans l'embouchure de la douille, vers l'arrière, jusqu'au voisinage immédiat de la zone périphérique du projectile, caractérisé en ce que, dans la zone de transmission centrale (16) du projectile entourée par la cage (20), entre la pointe (12') du projectile et le noyau principal (14'), celui-ci est prolongé vers l'avant par un cône de transition (15) auquel se raccordent vers l'avant des noyaux antérieurs (19.1 à 19.4) formés par des encoches (16.1 à 16.5) constituant des zones destinées à la rupture, de diamètre (d(e)) plus petit que le plus grand diamètre (d(a)) du cône de transition, lesdites encoches (16.1 à 16.5) étant en même temps le moyen d'assemblage par concordance de forme unique entre la cage (20) et le projectile.
2. Projectile selon la revendication 1, caractérisé en ce que les noyaux antérieurs (19.1 à 19.4) présentent des longueurs différentes.
