Definitions
- the invention relates to a watercraft with a shaped charge. Such watercraft are regularly used to clear objects, in particular mines.
- a mine is usually cleared by detonating the explosives present inside the mine by a charge from the outside.
- a shaped charge is usually used for this. What is important here, however, is that the explosive used in a mine itself can be difficult to ignite and only the detonator itself contains highly explosive material. It is therefore necessary to achieve a high energy input into the explosive of the mine in a volume. For this reason, shaped charges are usually used to ignite the explosive in a mine.
- a shaped charge projectile for combating underwater targets is known, an extendable arrangement being arranged in front of the shaped charge.
- a hollow explosive charge device for underwater use with a spacing space with an inflatable element is known.
- the object of the invention is to provide a watercraft in which an optimal introduction of energy into the explosive can be achieved regardless of the realizable distance between the watercraft and a mine.
- the watercraft according to the invention has a shaped charge.
- a gas space then adjoins the shaped charge in the effective direction of the shaped charge.
- the gas space is important because a plasma jet forms in this gas space when the hollow charge is ignited.
- the shape of the plasma jet and its speed are influenced by the length of the gas space in the effective direction.
- the gas space is variable in length in the effective direction of the shaped charge.
- the shape and speed of the plasma jet can be specifically adapted to the current requirements.
- the longer the gas space the narrower and faster the plasma jet becomes. With a shorter gas space, a wider plasma jet is generated at a lower speed.
- the energy loss between the watercraft and the mine can be optimized by varying the plasma jet.
- the length of the gas space is maximized when the distance between the watercraft and the mine is small and a comparatively fast plasma jet is thus generated.
- This rapid plasma jet suffers Although there is a greater attenuation in the water, since the distance is small, the energy losses are lower at a short distance compared to a broad, slow plasma jet.
- the gas space is shortened and a comparatively slow plasma jet is thus generated. This is slower and is therefore less weakened by the surrounding water. This means that a greater amount of energy arrives in the mine at a great distance.
- the shaped charge is arranged movably parallel to the effective direction of the shaped charge.
- the effective direction of the shaped charge is particularly preferably parallel to the longitudinal direction of the watercraft.
- the hollow charge is fixed and a boundary wall is movably arranged between the hollow charge and the outer shell of the watercraft, so that the length of the gas space between the hollow charge and the boundary wall can be adjusted by moving the boundary wall.
- the boundary wall has at least one further degree of freedom, for example can be tilted in one or two axes.
- a further design option for the plasma jet can thus be made possible.
- the shaped charge can be moved by means of a threaded rod.
- the advantage of this embodiment is the comparatively robust design.
- the length of the gas space can be varied between 0.1 times and ten times the diameter of the shaped charge. Particularly preferably, the length of the gas space can be varied between 0.5 times and seven times the diameter of the hollow charge.
- the watercraft has a distance detection device, wherein the distance detection device can detect the distance between the watercraft and an object, in particular a mine, arranged in front of the watercraft.
- the watercraft has a movement device for changing the length of the gas space.
- the watercraft has a control device, wherein the control device is designed to determine the optimal length of the gas space from the detected distance between the watercraft and the object arranged in front of the watercraft, and the direction of movement is designed to control the length of the gas space.
- the distance detection device comprises a sonar or an optical sensor such as a camera or a laser-based distance meter.
- the control device is designed to shorten the length of the gas space, the greater the distance between the watercraft and the object.
- the watercraft is an unmanned underwater vehicle.
- the watercraft is particularly preferably a remotely controlled unmanned underwater vehicle. With remote control, the hollow charge can be triggered safely and reliably by an operator at a safe location and on the basis of recognized protocols.
- the watercraft can also be an autonomous unmanned underwater vehicle, but this is not without problems due to the autonomous ignition of an explosive charge.
- FIG. 1 cross section In Fig. 1, a watercraft according to the invention is shown by way of example.
- a shaped charge 20 can be moved by means of a threaded rod 30.
- the distance between the hollow charge 20 and the envelope 40, where a gas space is located, is thus varied.
- the watercraft 10 can be moved via a propeller 70.
- the watercraft preferably has a battery 50 and a motor 60.
- a sonar 90 as a distance detection device, the distance to an object can be determined and the optimal position of the hollow charge 20 can thus be determined and controlled via a control device 80.
