DETAILED DESCRIPTION

[0078] FIG. 1 shows a schematic perspective view of a first partial region 12 of a main body 10 of a penetrator 1 according to the invention according to a first embodiment. Such a penetrator 1 can be used for engaging an armored target with reactive armor, in particular a tank with reactive armor.

[0079] The penetrator 1 is configured for a projectile with a tail unit, in particular a subcaliber kinetic energy projectile.

[0080] The penetrator 1 comprises a main body 10. The penetrator further comprises a head K and a tail unit H. The head K and the tail unit H can be configured as part of the main body 10 or attached to the main body 10. Preferably, the main body 10 is configured as a single piece.

[0081] Further, the main body 10 comprises at least one partial region 12 that comprises longitudinal recesses 20. The longitudinal recesses 20 are configured in an outer wall 13 of the main body 10.

[0082] In the at least one partial region 12 provided with the longitudinal recesses, the main body 10 of the penetrator 1 comprises a large selected outer diameter, which provides a high section modulus against bending with reduced cross-sectional area and mass compared to an equal-area circular cross-section.

[0083] The at least one partial region 12 with recesses 20 is configured in such a way that it comprises an increased surface moment of inertia compared to an equal-area circular cross section.

[0084] FIG. 2 shows a schematic perspective view of a main body 10 of a penetrator 1 according to the invention according to a second embodiment. The second embodiment is based on the first embodiment and only the differences between the first and second embodiment are set forth below.

[0085] The main body 10 shown in FIG. 2 comprises a first partial region 12′ having longitudinal recesses 20′ and a second partial region 12″ having longitudinal recesses 20′, wherein the second partial region 12″ is disposed behind the first partial region 12′ having longitudinal recesses 20′.

[0086] A third partial region 14 is arranged between the first partial region 12′ with longitudinal recesses 20′ and the second partial region 12″ with longitudinal recesses 20′. This can be a cylindrical partial region 14 as shown in FIG. 2. In the cylindrical partial region 14, there are no longitudinal recesses 20′ to ensure power transmission between the penetrator 1 and a sabot.

[0087] According to FIG. 2, the first partial region 12′ comprises three longitudinal recesses 20, in particular three longitudinal notches 20′, and the second partial region 12″ comprises six longitudinal recesses 20, in particular six longitudinal notches 20′.

[0088] As can be seen from FIG. 2, the longitudinal recesses 20 are distributed equidistantly in the first partial region 12′ and in the second partial region 12″.

[0089] FIG. 3 shows a schematic perspective view of a main body 10 of a penetrator 1 according to the invention according to a third embodiment.

The fourth embodiment is based on the first and/or second embodiment, and only the differences between the fourth embodiment and the first and/or second embodiment are set forth below.

[0094] The at least one partial region 12 is configured fluted. The longitudinal recesses 20″ are rounded and configured concavely in the outer wall of the main body 10 of the penetrator 1.

[0095] According to FIG. 4, three longitudinal recesses 20″ are shown. However, the number of longitudinal recesses 20 can also be larger.

[0096] Likewise, it is possible for the at least one partial region 12 to comprise longitudinal recesses 20, 20′, 20″ in the form of longitudinal grooves 20″.

[0097] FIG. 5 shows a sectional view of a partial region 12 with longitudinal recesses 20 of a main body 10 of a penetrator 1 according to the invention according to a fourth embodiment. The fifth embodiment is based on the first and/or second embodiment, and only the differences between the fifth embodiment and the first and/or second embodiment are set forth below.

[0098] According to FIG. 5, the partial region with longitudinal recesses comprises a plurality of longitudinal notches 20′. The number of longitudinal notches 20′ can be twelve, for example, as shown in FIG. 5, but more or fewer longitudinal notches 20 can also be configured.
