UNDERWATER VEHICLE HAVING A HOLLOW CHARGE WITH VARIABLE ACTION

Abstract

A watercraft may have a shaped charge and a gas chamber. The gas chamber may be adjacent to the shaped charge in a direction of action of the shaped charge. The gas chamber can be varied in length in the direction of action of the shaped charge. Further, the shaped charge may be movable parallel to the direction of action of the shaped charge. A threaded rod can be used to move the shaped charge. In some cases a length of the gas chamber is variable between 0.1-times and 10.0 times a diameter of the shaped charge. The watercraft may be configured in some instances as an unmanned underwater vehicle.

Claims

1.-5. (canceled)

6. A watercraft comprising: a shaped charge; and a gas chamber adjacent to the shaped charge in a direction of action of the shaped charge, wherein the gas chamber is variable in length in the direction of action of the shaped charge, wherein the shaped charge is movable parallel to the direction of action of the shaped charge.

7. The watercraft of claim 6 wherein the shaped charge is movable by way of a threaded rod.

8. The watercraft of claim 6 wherein a length of the gas chamber is variable between 0.1-times and 10.0 times a diameter of the shaped charge.

9. The watercraft of claim 6 comprising: a distance detection device configured to detect a distance between the watercraft and an object arranged in front of the watercraft; a movement device for changing the length of the gas chamber; and a control device configured to determine an optimum length of the gas chamber based on the distance that is detected between the watercraft and the object in front of the watercraft and control a direction of movement for adjustment of the length of the gas chamber.

10. The watercraft of claim 6 configured as an unmanned underwater vehicle.

Description

[0019] The watercraft according to the invention is explained in greater detail below with the help of an exemplary embodiment illustrated in the drawing.

[0020] FIG. 1 Cross section

[0021] FIG. 1 shows by way of example a watercraft according to the invention. A shaped charge 20 can be moved by means of a threaded rod 30. In this way, the distance between the shaped charge 20 and the casing 40 is varied, where a gas chamber is located. The watercraft 10 can be moved by means of a propeller 70. The watercraft preferably has a battery 50 and a motor 60 for this purpose. The distance from an object can be determined using sonar 90 as the distance detection device, and the optimal position of the shaped charge 20 can thereby be determined and controlled by means of a control device 80.
