Definitions
- the present invention relates to a defense system against missiles, preferably with rotors.
- Corresponding missiles are available in different sizes, which can be unmanned, but also manned.
- the unmanned missiles with such rotors are often referred to as drones.
- These missiles can have one or more rotors.
- Such missiles Due to the popularity and easy availability of such missiles, they are increasingly perceived as a threat. On the one hand, such missiles can be equipped with a weapon system or reconnaissance means, on the other hand, they could also hinder conventional vehicles and airplanes and, in the worst case, render them unable to navigate.
- such missiles with rotors can pose a threat if they occur in swarms and / or suddenly, ie if they fly in large numbers in a spatially limited location.
- DE 102015011 058 A1 discloses a defense system using non-lethal means. Projectiles made of non-lethal materials are used. A laser is also disclosed for defense. However, only one threat is effectively warded off over time.
- DE 102015 011 579 A1 discloses a drone defense through a network. However, only a small area can be defended, namely that of the network. Drones can also easily recognize such a network and circumvent it if necessary.
- the present invention thus claims a defense system against missiles with rotors or nozzles, the defense system containing at least one non-Newtonian fluid.
- a non-Newtonian fluid is a liquid or gaseous fluid that solidifies or liquefies under mechanical influence.
- Normal fluids or Newtonian fluids are fluids with linear viscous flow behavior. This means that the mechanical action has a proportional effect on the flow behavior of the fluid.
- non-Newtonian fluids are designed in such a way that they change their viscous flow behavior nonlinearly when subjected to mechanical action.
- the above-mentioned behavior is used by the present invention to influence the movement of the missile rotors. If a missile to be defended with rotors can no longer move them functionally, this leads to unstable flight behavior which can cause the missile to crash and / or render the missile harmless.
- the invention proposes to use at least one non-Newtonian fluid in order to introduce it into the area of the missiles to be defended with rotors or nozzles.
- the defense system also consists of at least one application agent for the non-Newtonian fluid.
- the non-Newtonian fluid is introduced into the flight area of the missiles to be defended.
- the movement of the rotors acts mechanically on the non-Newtonian fluid that is deployed. Because the viscosity of the non-Newtonian fluid is changed during this mechanical action, the non-Newtonian fluid impedes the movement of the rotors of the missiles to be defended.
- the flight behavior of the missile to be defended is preferably changed in such a way that it is brought to a crash. This effect can also be applied to nozzles because it does this is also mechanically acted on the non-Newtonian fluid.
- a non-Newtonian fluid with a dilatant action is preferably proposed in order to slow down the rotor movement of the missiles to be defended.
- the viscosity in the area of the rotors increases with mechanical action due to the movement of the rotors on the non-Newtonian fluid, as a result of which the rotors rotate more slowly or the buoyancy forces are reduced and the missile to be deflected thus falls.
- the high viscosity of the surrounding fluid prevents the rotors from moving, which reduces the speed of the rotors.
- a non-Newtonian fluid in which the viscosity decreases under mechanical stress, that is, structurally viscous or shear-thinning fluids. This can also change the flight behavior of the missiles to be defended. If the rotors move in an environment in which they receive less resistance than through normal air, the rotor of these missiles rotates faster than in normal air. This also makes these missiles unstable in flight behavior and can thus lead to defense.
- the proposed non-Newtonian fluid can be a mixture of solid and liquid. It can also be a mixture of solid and gas. Water and starch are given here as an example of a dilatant, non-Newtonian fluid as a mixture of solid and liquid. Zinc compounds are also known to have a dilatant effect. In contrast, many dispersions have a pseudoplastic appearance.
- the non-Newtonian fluid is applied in the target area by the application means.
- the application means can be designed as a thrower.
- a projectile is proposed which contains the non-Newtonian fluid. Such a projectile can then be ejected into the target area by a spreading means which is designed as a thrower.
- the throwing body then contains a cutting set, which rather distributes the non-Newtonian fluid in the target area.
- a cutting set which rather distributes the non-Newtonian fluid in the target area.
- Such application occurs in the target area through a local distribution of the non-Newtonian fluid.
- the dispensing means can furthermore be designed as a nozzle which dispenses the non-Newtonian fluid in the target area continuously or at fixed intervals.
- the application of the non-Newtonian fluid in the target area through a nozzle is always advantageous when threats are to be warded off in an area close to the nozzle. Application by a thrower is recommended for an area further away.
- the non-Newtonian fluid can be premixed and distributed by the application agent in the defense area.
- the non-Newtonian fluid is only mixed in the target area.
- This embodiment has the advantage that, when deployed, no mechanical forces act on the non-Newtonian fluid, which can influence the viscose behavior of the non-Newtonian fluid even before contact with the missiles to be defended.
- the components in the application means are applied separately.
- the application means as a nozzle
- this is divided, so that the materials used for the non-Newtonian fluid are applied simultaneously, namely each component from a part of the nozzle.
- the fluid is mixed in the air by the simultaneous application.
- the non-Newtonian mode of action of the fluid thus only arises when mixed in the air.
- the throwing body can have different chambers in which the individual components of the non-Newtonian fluid are accommodated.
- the disassembly of the individual components in the chambers then ensures the distribution and mixing in the air.
- the non-Newtonian fluid is only created in the target area with this type of application, namely by mixing the materials in the air.
- sensors which can detect missiles to be defended.
- Such sensors can be imaging sensors that can recognize corresponding missiles by means of a downstream image processing or motion sensors that react to objects of a certain size.
- a simple camera as a sensor is also conceivable, an observer then being able to trigger the defense system after detection of corresponding missiles.
- the defense system furthermore contain a control which, after detection of at least one missile to be deflected, is the application means activated independently for the non-Newtonian fluid.
- the sensors pass on corresponding messages to the control and the latter then activate the application means for the non-Newtonian fluid.
- activation can be done electrically or pyrotechnically, but also hydraulically or pneumatically when using a nozzle.
- the non-Newtonian fluid after the non-Newtonian fluid has been applied, it will act on the rotors of the missiles to be defended.
- the rotation of the rotors is influenced by the dilatant or pseudoplastic action of the non-Newtonian fluids. Such an influence makes the flight behavior of the missile to be defended unstable to unpredictable. This makes it possible to effectively ward off missiles with rotors, in particular several such missiles at the same time.
- the defense system thus repels missiles in a limited area, namely in the area in which the non-Newtonian fluid is applied. All missiles with rotors or nozzles that move into this area are affected by the defense function.
- the non-Newtonian fluid as proposed in this invention can be perceived as foam or mist due to its composition in the target area.
- Light components for the non-Newtonian fluid are preferred use so that the fluid stays in the air for a long time in the target area. The heavier the components of the fluid are, the more likely the fluid will fall to the ground where it is ineffective.
- the invention is not restricted to the aforementioned features. Rather, further configurations are conceivable.
- wind-generating elements could be provided that guide or hold the non-Newtonian fluid that has been applied in a certain range. This makes it possible to extend the effectiveness of the defense system.
- the deployment of drones is also conceivable.
