Description

  • 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.
  • Such an arrangement is known from ' FR-A-25 29 319. There, an increase in the final ballistic performance is achieved by advancing the outer edge of the gas pressure receiving surface of the sabot for the propellant gases in the axial vicinity of the rear edge of the inflow surface for the air. This creates additional space for the propellant charge around the rear area of the sabot without significantly changing the weapon-side cargo space and / or increasing the overall length of the ammunition unit, consisting of the sleeve, sabot and missile. In addition, an attack of the axial propellant pressure is achieved far in front of the center of gravity of the missile and thus the centering in the tube is promoted. Furthermore, the gas pressure receiving surface formed as a sagging profile also results in a radially acting propellant gas pressure in the tube, as a result of which a reliable positive connection is achieved in the transmission area between the propellant cage and the missile.
  • In contrast, 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 essential features of the invention to achieve the stated object are mentioned in the characterizing part of claim 1, the subclaim mentions an embodiment of the invention.
  • The Fig. Shows an embodiment of the new arrangement in side elevation after a longitudinal axis section. In the arrangement shown, the penetration performance of the missile against multi-plate targets is improved - even under difficult conditions. For this purpose, 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. Through the transition cone 15, a slim main penetrator 14 'can be realized via a rear extension. 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, on the one hand, results in increased performance through an increased load. On the other hand, 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. Overall, 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.
  • In the new arrangement, 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. Segmental sabot (20) with a front air compartment, the forward part of the sabot being secured in a propulsive charge casing, the sabot interlockingly surrounding the middle zone of an arrow-stabilized projectile (10) of high length-to- diameter ratio from a position starting immediately behind the nose (12') of the projectile, the sabot being provided at the rear with a gas pressure receiving surface (22), which extends to form a profile which falls away from an outer edge of the sabot and located immediately behind the point at which the sabot is secured in the mouth of the casing, as far as a point at the rear of the sabot close to the peripheral zone of the projectile, characterized by the fact that in the central transmission part (16) of the projectile surrounded by the sabot (20), and between the nose (12') of the projectile and the main core (14'), the latter is extended towards the front by a transition cone (15), which is followed to the front by preliminary cores (19.1 to 19.4) formed by incisions (16.1 to 16.5) which define preset breaking points and of which the diameter (de) is smaller than the maximum diameter (da) of the transition cone, the said incisions (16.1 to 16.5) also constituting the only form-closure means between the sabot (20) and the projectile.
2. Projectile in accordance with Claim 1, characterized by the fact that the preliminary cores (19.1 to 19.4) vary in length.
