Definitions
- the invention relates to a removable cage for a sub-caliber projectile according to the preamble of claim 1.
- Driver cages for large-caliber KE and KE practice projectiles that are fired from smooth-tube guns are predominantly provided with a guide band made of plastic, in particular polyamide, which has predetermined breaking points in the area of the joints of the sabot segments. During the opening phase of the sabot, a separation of the guide belt through these predetermined breaking points should then be initiated.
- the object of the present invention is to further develop a sabot of the type mentioned at the outset in such a way that reproducible detachment of the sabot segments can be achieved in a simple manner, regardless of the moisture content of the respective guide belt.
- the invention is based on the idea of subsequently providing guide belts of a known type with a slot-shaped longitudinal groove in the region of the joints of the sabot segments.
- This longitudinal groove preferably extends over at least (30%) of the width of the guide belt and has a course that is chosen such that there is no circumferential crack formation in the guide belt area during the opening process of the respective sabot.
- a predeterminable area with guide band material should remain in order not to impair the eyelid function of the guide band at this point when firing.
- Fig. 1 denotes a sub-caliber projectile which essentially consists of a wing-stabilized penetrator 2 and a two-flange drive cage 3.
- the sabot 3 is composed of three segments 4-6 (FIG. 2), which together form the parting lines 7-9 and which are held together in the region of the rear flange (pressure flange) 10 with the aid of a guide belt 11.
- longitudinal grooves 12-14 are provided in the guide band 11 along the parting lines 7-9, which cause the guide band 11 to tear out along these grooves as soon as the projectile 1 leaves the respective weapon barrel.
- the longitudinal groove 12 runs parallel to the longitudinal axis 15 of the floor (FIG. 1) and has a length 16 which covers almost the entire width 17 of the guide band 11 .
- the course of the longitudinal groove 16 facing the penetrator is selected such that the guide band 11 is weakened in the region of the parting line 7, but tearing of the guide band in the circumferential direction is reliably avoided.
- the longitudinal section 12 producing the longitudinal section is guided through the guide band 11 so that webs in the substructure, which are required for the tight fit of the guide band 11, are included in the sectional profile of the longitudinal groove 12 in such a way that sharp Changes in cross-section of the guide band profile, at which the crack to be avoided can be deflected in the circumferential direction, are compensated for.
- An axial crack progression is thus achieved reliably and reproducibly.
- the cutting width should not exceed 0.6 mm, so that it is ensured that it is completely closed when it is pressed into the transition cone of the gun barrel (not shown) by displaced guide band material, so that the sealing function of the guide band 12 is in no way impaired.
- the length and depth of the longitudinal grooves 12 produced by cuts are to be adapted to the respective guide belt geometry. Sharp changes in cross-section must be compensated for by the cut. On the other hand, sufficient cross-sectional area must be maintained to ensure the holding function of the guide belt.
- the longitudinal groove 12 'and 12' ' is also formed such that radial tearing in the circumferential direction of the guide band 11 is reliably avoided, but in which the length of the longitudinal groove is somewhat is less than in the embodiment shown in FIG. 3.
- the length 16 should, however, be at least 30% of the length of the width 17 of the respective guide belt 11.
- the longitudinal groove should not begin directly at the rear end of the guide band 18 (FIG. 3), but only after a distance 19, which must be determined experimentally for the respective projectile type.
