Definitions

  • the disclosure relates to a device, a method and a system for defending against flying objects.
  • Possibilities and devices for defending against flying objects are known from the prior art, which are based, for example, on disrupting radio signals.
  • continued flight cannot always be reliably prevented, e.g. if the flying object is autonomous and self-sufficient.
  • the nets are fired from the ground towards the flying objects or transported by airborne devices.
  • soldiers for example in tanks or on foot, often travel in dusty, impassable and/or confusing terrain where visibility can be severely limited.
  • a flying object is provided with an interceptor, wherein the interceptor has a hollow body with an opening and a locking mechanism and a first rope with at least a first body arranged at the first end of the rope.
  • the first rope is arranged inside the hollow body and is held by the locking mechanism. After the locking mechanism has been released, e.g. when there is local proximity to a flying object that is to be brought down, the first end of the first rope with the first body emerges from the interior of the hollow body through the opening under the effect of gravity.
  • a method for defending against a flying object using a flying object with an interceptor includes sending the flying object with an interceptor in the direction of the flying object, approaching the flying object with the flying object with an interceptor, releasing the locking mechanism and flying over the flying object in such a way that the first cable hits the flying object.
  • a flying object defense system includes a flying object with an interceptor and a cassette for sending out the flying object with an interceptor.
  • the cassette has a capacity of at least 1, preferably at least 6, preferably at least 12, particularly preferably at least 24 flying objects with an interceptor.
  • the cassette can also be designed in such a way that it can hold different flying objects.
  • Figures 1A to 1C show schematically flying objects for defense against flying objects according to some embodiments.
  • Figure 2 shows schematically an interception device of a flying object according to an embodiment in a perspective view.
  • Figure 3 shows schematically the interception device of a flying object Figure 2 in a sectional view before releasing a locking mechanism.
  • Figure 4 shows schematically the interception device of a flying object Figure 2 in a sectional view after releasing the locking mechanism.
  • Figures 5A and 5B show schematically flying objects after defense by a flying object according to a further embodiment in a perspective view.
  • Figure 6 shows schematically the use of a system for defending against flying objects according to one embodiment in a first phase in a side view.
  • Figure 7 shows schematically the use of a system for defending against flying objects according to the embodiment Figure 6 in a second phase in a side view.
  • a flying object according to the techniques disclosed herein repels flying objects with the aid of a first rope arranged in a hollow body of the interceptor and at least one first body arranged at a first end of the first rope, in that the first rope and at least the first body are at least partially and/or partially traverse a surface of rotation of a rotor of the flying object and/or touch a part of the flying object such that the first rope with the first body wraps around parts of the flying object.
  • the first rope is held inside the hollow body by a locking mechanism.
  • the first rope can be releasably attached to the hollow body so that it can be thrown off completely.
  • the first body supports the "wrapping" in the manner of a slingshot, since the first rope is brought towards the flying object at a certain relative speed and, due to inertia, the first body creates a circular path around the flying object when the first rope hits the flying object Object accomplished.
  • this disclosure describes the defense against flying objects with a flying object with an interceptor.
  • the “flying object” can be an unmanned aircraft, a drone, a small drone or similar.
  • Drone also includes copters, e.g. so-called quadrocopters or octocopters.
  • further embodiments of unmanned flying objects of different sizes are included, which are designed to be autonomous, remotely controlled and/or self-sufficient.
  • flying object can be understood to mean all of the above-mentioned flight-capable objects.

  • Each flying object has at least one rotor, each with a surface of rotation.
  • the “area of rotation” corresponds to a substantially round area in which the at least one rotor rotates.
  • rope refers to an elongated object that essentially absorbs no compressive forces.
  • the rope can be made of any material that is suitable for damaging a rotor and/or for withstanding a rotational movement of the rotor in such a way that the rope is not destroyed.
  • the rope can, for example, consist of a composite material and/or have a structure that makes it more resistant to forces acting transversely to a longitudinal axis of the rope.
  • the rope can be made of aramid fibers, an example is DuPont TM Kevlar ® . “Transverse” also includes forces at an angle to the longitudinal axis.
  • a flying object according to some embodiments can be arranged in a vehicle, in particular an armored vehicle, for example in a cassette.
