Definitions
- the invention relates to the destruction of sea mines by means of an underwater vehicle as part of what is known as mine hunting.
- the underwater vehicle drives head-on towards the mine. If the underwater vehicle has arrived at the mine, for example when it comes into contact with the mine, the underwater vehicle is connected to the mine. This can be done by driving (i.e. ramming) a spike into the mine. The mine can then be safely detonated by means of explosives on board the underwater vehicle, for example a shaped charge, or it detonates as soon as the dome is driven in. Alternatively, the explosive charge can be detachably connected to the underwater vehicle so that only the explosive charge is connected to the mine. The underwater vehicle can then move away from the mine site and survive the detonation. Furthermore, it is also possible for the explosives of the underwater vehicle to detonate upon contact with the mine, for example by an impact fuse, and thus also cause the mine to detonate.
- the underwater vehicle should hit the mine head-on and as precisely as possible at a planned point in order to detonate it safely.
- turbulences of the water
- the underwater vehicle has to go through these to get to the sea mine. Due to the forces prevailing in the turbulence, the underwater vehicle can deviate from its planned route and not hit the sea mine properly or not at all. Then a second attempt is necessary to hit the sea mine. This unnecessarily costs time and there is no guarantee that the sea mine will be hit at the second attempt.
- the submersible is so unfavorably connected to the sea mine that the explosives of the submersible are detonated, but part of the energy is detonated Sea mine missed and this is not detonated sympathetically. Then a second underwater vehicle has to be used to destroy the sea mine, which is a significant cost factor.
- the object of the present invention is therefore to create an improved concept for underwater vehicles.
- Exemplary embodiments show an underwater vehicle for destroying sea mines.
- the underwater vehicle includes an enveloping body, a flywheel and a drive unit for the flywheel.
- the enveloping body can protect the underwater vehicle against the ingress of water.
- the flywheel is also known as the flywheel.
- the centrifugal mass has an axis of rotation that corresponds to a longitudinal axis of the underwater vehicle.
- the axis of rotation is also referred to as the main axis of rotation.
- the flywheel is non-gimballed (i.e., the flywheel exhibits the absence of a gimbal) such that the axis of rotation is the only axis about which the flywheel moves.
- the centrifugal mass has exactly one degree of freedom.
- a fictitious line between the bow and the stern of the underwater vehicle, arranged in particular centrally through the underwater vehicle is referred to as the longitudinal axis of the underwater vehicle.
- the longitudinal axis can also be referred to as the roll axis. The fact that the axis of rotation and the longitudinal axis correspond means that the axis of rotation lies in the longitudinal axis.
- the drive unit is designed to set the centrifugal mass in rotation before the underwater vehicle hits the sea mine and after the underwater vehicle has entered the water. This means that the drive unit sets the centrifugal mass in motion before the watercraft has to cross the sea mine's turbulence. Furthermore, it is advantageous to use the flywheel just like that let it run as short as possible. Otherwise the maneuverability of the submersible would be restricted.
- An (electric) motor can be used as the drive unit.
- the drive unit can also have a controller (eg a processor/computer) in order to control the motor, ie to start it and optionally brake it.
- the idea is to use the flywheel to increase the inertia of the underwater vehicle in the yaw axis (also known as the vertical axis) and pitch axis (also known as the transverse axis).
- the underwater vehicle is more robust against the effects of turbulence.
- This concept makes it possible to build underwater vehicles for mine destruction more easily and still reliably hit the mine.
- the concept compensates for the lower mass inertia compared to heavier submersibles and ensures that the lighter submersible is not more susceptible to turbulence.
- switching on the flywheel while driving does not affect the maneuverability of the underwater vehicle before the flywheel is switched on. When the flywheel is switched on, the maneuverability of the submersible is reduced due to the higher inertia.
- the underwater vehicle has a braking unit which is designed to brake the flywheel mass in its own movement before the drive unit causes the flywheel mass to rotate.
- the braking unit can be any device suitable for preventing the flywheel from rotating.
- the intrinsic movement of the centrifugal mass can arise, for example, when the underwater vehicle rolls.
- the drive unit is designed to brake the flywheel mass in its own movement before the drive unit causes the flywheel mass to rotate.
- the motor used can generate a stall torque that opposes the intrinsic movement, ie the intrinsic torque, of the flywheel mass, so that the flywheel mass stands still.
- the underwater vehicle has a control unit which is designed to steer the underwater vehicle towards the sea mine and bring it into contact with the sea mine in order to enable the sea mine to detonate.
- the control unit can have a controllable flow element, for example a rudder, with which a direction of travel of the underwater vehicle can be actively influenced.
- the control unit can also include a controller (eg a processor/computer) in order to control the flow element.
- the control unit can steer the underwater vehicle in a straight line towards the sea mine.
- a straight-line journey means that the underwater vehicle is not planned to change direction. However, changes in direction caused by currents or other external forces acting on the underwater vehicle can, of course, be compensated for by the control unit.
- the drive unit then sets the flywheel in motion after the underwater vehicle has started traveling in a straight line in the direction of the sea mine.
- the drive unit is designed to set the flywheel in rotation in such a way that the flywheel has reached a specified speed immediately, i.e. for example a maximum of 1 second, a maximum of 2 seconds or a maximum of 5 seconds before entering a turbulence in the surrounding water caused by the sea mine .
- a rotation speed or a range of the rotation speed of the centrifugal mass that is sufficient to stabilize the underwater vehicle in the turbulence caused by the sea mine can be regarded as the intended speed.
- This rotational speed or this range can be defined in advance and must be adapted to the vehicle to be stabilized.
- a rotational speed that at least corresponds to the manufacturer's specifications for normal operation of the flywheel can be regarded as the intended speed.
- a starting speed of the flywheel mass ie the time that the flywheel masses from standstill to reaching the intended speed required, selected such that a metacentric height of the underwater vehicle or, additionally or alternatively, an active compensation of the underwater vehicle, prevents the underwater vehicle from rolling.
- the enveloping body comprises a body of revolution.
- the longitudinal axis of the enveloping body then corresponds to the axis of rotation of the body of rotation.
- the underwater vehicle has flow elements, for example rudders, arranged on the enveloping body.
- the flow elements are designed to counteract a torque of the underwater vehicle. That is, in particular, the flow elements can prevent the underwater vehicle from performing a rolling movement.
- the controller can control the flow elements in such a way that it counteracts a torque transmitted to the underwater vehicle by a rotation of the centrifugal mass. This takes place in particular in that the flow elements are controlled in opposite directions.
- the flow elements can also be used for course control. However, the flow elements are then preferably controlled in the same way.
- the centrifugal mass is arranged in a front third of the underwater vehicle, preferably in a front quarter of the underwater vehicle. This is advantageous because the underwater vehicle enters the turbulence nose first, i.e. bow first. Because the centrifugal mass is arranged in the front part of the underwater vehicle, this part of the submersible is stabilized and the submersible travels straighter through the turbulence than if the centrifugal mass were arranged in a rear part of the underwater vehicle.
- Method for destroying sea mines with an underwater vehicle with the following steps: arranging a centrifugal mass in the underwater vehicle, so that an axis of rotation of the centrifugal mass corresponds to a longitudinal axis of the underwater vehicle; Setting the centrifugal mass in rotation before the underwater vehicle hits the sea mine and after the underwater vehicle has entered the water.
- the controllers (or processors/computers) mentioned can be the same physical assembly, i.e. the same controllers. In other words, all or any selection of the processes executed by the controllers can run on the same controller.
- FIG. 1 in FIG. 1a an exemplary, schematic lateral sectional representation and in FIG. 1 b an exemplary, schematic frontal sectional representation of an underwater vehicle;
- FIG. 2 in FIG. 2a an exemplary, schematic lateral and in FIG. 2b an exemplary, schematic frontal sectional representation of the underwater vehicle according to exemplary embodiments.
- FIG. 1a and 1b show an exemplary embodiment of an underwater vehicle 20, with FIG. 1a revealing a schematic lateral sectional view and FIG. 1b revealing a schematic frontal sectional view.
- the underwater vehicle 20 includes an enveloping body 22, a centrifugal mass 24 and a drive unit 26.
- the enveloping body 22 protects the underwater vehicle 20, for example, against the ingress of water.
- the centrifugal mass 24 has an axis of rotation 28 which corresponds to a longitudinal axis 30 of the underwater vehicle 20 .
- the drive unit 26 causes the centrifugal mass 24 to rotate before the underwater vehicle 20 hits the sea mine and after the underwater vehicle 20 has entered the water.
- a shaft of the drive unit 26, in particular of a motor of the drive unit 26 lies in the axis of rotation 28.
- a rotation arrow 32 indicates the rotation of the centrifugal mass 24.
- the centrifugal mass 24 is arranged in the figure in the front quarter of the underwater vehicle 20, but can be arranged at any other position in the underwater vehicle.
- FIG. 2a and 2b show an exemplary embodiment of an underwater vehicle 20, with FIG. 2a revealing a schematic lateral sectional view and FIG. 2b revealing a schematic frontal sectional view.
- Fig. 2a and Fig. 2b show extensions to Fig. 1a and Fig. 1b.
- FIG. 2a an optional control 34 is shown in FIG. 2a.
- the controller 34 can take over various control (and regulation) tasks of the underwater vehicle.
- the controller 34 may optionally be part of the power unit when a power unit motor 26 and the power unit controller 34 are separate.
- the underwater vehicle 20 optionally has a brake unit 36 .
- the brake unit 36 can brake the movement of the flywheel 34 before the drive unit 26 causes the flywheel to rotate.
- the braking and thus also the stopping of the centrifugal mass can take place by means of known brakes.
- the braking effect in the illustration in FIG. 2a can be generated by the braking unit 36 coming into contact with the flywheel mass 24 .
- the movement of the braking unit 36 required for this is indicated by the double arrow 38 .
- the associated control of the brake unit 36 can also be taken over by the controller 34 .
- the control is in the braking unit 36 integrated.
- the drive unit can also perform the braking and thus also the stopping of the centrifugal mass 24.
- an optional flow element 40 is arranged on the underwater vehicle 20 or the enveloping body 22 in FIG. 2 .
- the flow element can counteract a torque of the underwater vehicle 20 .
- the flow element can thus, for example, prevent or slow down a rolling movement of the underwater vehicle.
- the rolling movement of the underwater vehicle can be generated by a propeller drive, for example.
- turbulence in the water for example caused by the sea mine, can also cause the underwater vehicle to roll.
- the flywheel itself in particular the acceleration of the flywheel, can also lead to a rolling movement of the underwater vehicle.
- the rolling motion shortly before reaching the mine unlike a pitching or yawing motion, is not problematic for the course of the underwater vehicle and can in principle be tolerated.
- the flow element 40 can also compensate for the rolling movement of the underwater vehicle.
- the flow element 40 can be controlled by the controller 34 .
- the flow elements 40 can optionally also control a travel direction of the underwater vehicle 20 .
- the flow elements can control the underwater vehicle 20 when they are deflected in the same direction, while a torque of the underwater vehicle can be compensated for when the flow elements are deflected in an opposite direction.
- the underwater vehicle can also have propellers as the flow element.
- the underwater vehicle can be driven by means of a four-propeller drive.
- the two propellers on one diagonal can then have a different rotational speed than the two propellers on the other diagonal.
- the enveloping body comprises a body of revolution both in FIG. 1 and in FIG. 2 .
- the enveloping body advantageously consists of a body of revolution.
- Other device features attached to the enveloping body, such as the flow element 40 do not stand in the way of this.
- the longitudinal axis 30 of the enveloping body then forms the axis of rotation of the body of rotation.
- the underwater vehicle can have hydrophones, for example for orientation.
- the (water) sound transducers disclosed are designed for use under water, in particular in the sea.
- the sound converters are designed to convert waterborne sound into an electrical signal (e.g. voltage or current) corresponding to the sound pressure, the waterborne sound signal.
- the sound converters are designed to convert an applied electrical voltage into waterborne sound. Accordingly, the sound converters can be used as waterborne sound receivers and/or as waterborne sound transmitters.
- the sound transducers have a piezoelectric material, for example a piezoceramic, as the sensory material.
- the transducers can be used for (active and/or passive) sonar (sound navigation and ranging). The transducers are not suitable for medical applications.
- aspects have been described in the context of a device, it is understood that these aspects also represent a description of the corresponding method, so that a block or a component of a device is also to be understood as a corresponding method step or as a feature of a method step. Similarly, aspects described in connection with or as a method step also constitute a description of a corresponding block or detail or feature of a corresponding device.
