UNDERWATER VEHICLE COMPRISING TWO SHAPED CHARGES ARRANGED BEHIND ONE ANOTHER

Abstract

A watercraft may include a first shaped charge as well as a second shaped charge. The second shaped charge may be positioned behind the first shaped charge in an effective direction of the first shaped charge. The effective direction of the first shaped charge and an effective direction of the second shaped charge may run to a common target point. At least one of the first shaped charge or the second shaped charge is movable. Further, a distance sensor may be configured to detect a distance between the watercraft and an object positioned in front of the watercraft. An electronic evaluation and control system can process the distance that is detected by the distance sensor and move at least one of the first shaped charge or the second shaped charge based on the distance that is detected.

Claims

1.-8. (canceled)

9. A watercraft comprising: a first shaped charge; a second shaped charge disposed behind the first shaped charge in an effective direction of the first shaped charge, wherein the effective direction of the first shaped charge and an effective direction of the second shaped charge extend to a common target point, wherein at least one of the first shaped charge or the second shaped charge is movable; a distance sensor configured to detect a distance between the watercraft and an object positioned in front of the watercraft; and an electronic evaluation and control system configured to process the distance that is detected by the distance sensor, wherein the electronic evaluation and control system is configured to move at least one of the first shaped charge or the second shaped charge based on the distance that is detected.

10. The watercraft of claim 9 wherein the effective direction of the first shaped charge and the effective direction of the second shaped charge are parallel.

11. The watercraft of claim 9 wherein a main extent of the watercraft extends in a longitudinal direction, wherein the effective direction of the first shaped charge and the effective direction of the second shaped charge are arranged in the longitudinal direction of the watercraft.

12. The watercraft of claim 9 wherein the first shaped charge and the second shaped charge are movable, wherein a distance between the first shaped charge and the second shaped charge is constant.

13. The watercraft of claim 9 wherein the first shaped charge includes a first fuse, wherein the second shaped charge includes a second fuse, wherein the first fuse and the second fuse are connected to an ignition device, wherein the ignition device includes a delay device configured to cause a delayed ignition of the second fuse.

14. The watercraft of claim 9 comprising: a first gas chamber disposed between the first shaped charge and a casing of the watercraft; and a second gas chamber disposed between the first shaped charge and the second shaped charge, wherein a length of the first gas chamber in the effective direction of the first shaped charge is smaller than a length of the second gas chamber in the effective direction of the second shaped charge.

15. The watercraft of claim 14 wherein the first gas chamber positioned in front of the first shaped charge in the effective direction of the first shaped charge is shorter than the second gas chamber positioned in front of the second shaped charge in the effective direction of the second shaped charge.

16. The watercraft of claim 9 wherein the distance sensor is sonar.

Description

[0023] The watercraft according to the invention is explained in greater detail below with the help of an exemplary embodiment illustrated in the drawings.

[0024] FIG. 1 Watercraft

[0025] FIG. 2 Watercraft having movable shaped charges

[0026] In FIG. 1 the watercraft 10 is shown as a schematic cross section. The watercraft 10 has a battery 50, a motor 60, and a propeller 70 for propulsion. Alternatively, the watercraft 10 may also comprise multiple motors 60 and propellers 70. A first shaped charge 21 and a second shaped charge 22, which are aligned with the effective direction in the longitudinal direction of the watercraft and in the travelling direction of the watercraft 10, are arranged in the watercraft 10. It can be seen that the first gas chamber lying between the first shaped charge 21 and the casing 40 is shorter than the second gas chamber, which is arranged between the second shaped charge 22 and the first shaped charge 21. In this way, the second plasma beam of the second plasma charge 22 is more focused. The watercraft 10 has an ignition device 100, in order to ignite the first shaped charge 21 and the second shaped charge 22. In the example shown, the ignition device 100 is arranged in such a manner that the central core of the ignition device 100 has a longer connection to the second shaped charge 22 than the connection to the first shaped charge 21, so that the connection from the central core of the ignition device to the second shaped charge 22 acts as a delaying device. In addition, the watercraft 10 comprises sonar 90, in order to determine the distance of the watercraft 10 from a mine.

[0027] In addition, the watercraft 10 shown in FIG. 2 comprises a threaded rod 30, with which the first shaped charge 21 and the second shaped charge 22 can be jointly displaced. In this way, the widening of the plasma beam of the first shaped charge 21 can be changed. On the other hand, due to the constant distance between the first shaped charge 21 and the second shaped charge 22, the shape of the second plasma beam remains unchanged.
