Definitions

  • the invention relates to an intervention system for defense against targets in the form of RAM targets and / or UAVs with the features of the preamble of claim 1. Furthermore, the invention relates to a method for defense against RAM targets and / or UAVs with the features of the preamble of Claim.
  • the intervention system is suitable for fighting unmanned aerial vehicles in the form of so-called UAVs (Unmanned Areal Vehicles), which can be operated and navigated without a crew on board by a computer or from the ground via a remote control.
  • UAVs Unmanned Areal Vehicles
  • the intervention system is able to fight RAM (Rocket, Artillery and Mortar) targets such as missiles, artillery and mortar shells.
  • RAM Random, Artillery and Mortar
  • Such intervention systems are also known as C-RAM systems or Counter-RAM systems (Counter Rocket Artillery and Mortar).
  • Missiles or automatic cannons are expensive, especially if they have to be used in large numbers.
  • the ammunition has shaped charges that are distributed over the circumference and act transversely to the longitudinal axis of the ammunition and a flyby ignition system.
  • the ammunition is designed as a missile with a warhead.
  • the warhead has a target recognition device.
  • a tracking device rotates the shaped charge in the direction of the flight target. At the moment the detonation is triggered, the shaped charges are aligned in their effective direction at the flight target by means of the flyby ignition system.
  • the defense drone has a motor for driving a propeller, a fuselage connected to the motor, one on the fuselage arranged effector and a device for dropping the effector.
  • the effector comprises threads which are made of a material suitable for blocking the moving parts of the small drone.
  • the effector has a sheath encompassing the threads and an ejection means received in the sheath and an activation means.
  • Such a defense drone is not suitable for fighting RAM targets.
  • the unmanned aerial vehicle known for the combat against ground targets.
  • the unmanned flying object is designed as a drone with a propeller.
  • the unmanned aerial vehicle has a homing device and a combat charge capable of detonation. At least one projectile-forming charge is available as combat charge.
  • the at least one load is arranged in a stationary manner in the aircraft.
  • the corresponding charge arrangement consists of two or more axially parallel charges that are ignited simultaneously.
  • the aircraft is designed as a drone with delta wings and a multi-part fuselage.
  • An engine with a propeller is located in a stern section.
  • a detection device for detecting a target corridor is arranged in the fuselage.
  • the invention is therefore based on the object of providing a cost-effective method and a cost-effective intervention system against RAM targets and / or against enemy UAVs / drones.
  • the intervention system according to the invention has several UAVs or drones, each of which is equipped with an effector to combat C-RAM targets and / or UAVs, the drones being arranged around the object in a standby mode, the drones each having an effector in Have the form of an explosive charge arrangement, the drones being designed as multicopters. This enables cost-effective combat against C-RAM targets and UAVs.
  • the method according to the invention is characterized in that several drones of the intervention system are arranged around the object in a standby mode, with drones in the form of multicopters each with an effector in the form of an explosive charge arrangement being used, a trajectory of the target being calculated in advance and that of the trajectory next adjacent drone is steered onto the trajectory or close to the trajectory of the target, the target being fought by detonating the explosive charge arrangement when the target approaches this adjacent drone.
  • a certain destruction results from the fact that a detonator of the target is sighted. This also has the advantage that the debris is divided into small pieces and thus causes little damage.
  • the intervention system is preferably suitable for protecting objects such as buildings or vehicles. Even slowly moving objects can be well protected by drones in the form of multicopters. Since the drones are mobile, moving objects can also be protected.
  • the drones are initially ready to start or are already floating around the object to be protected in a standby mode. In the standby mode, the drones hover in particular evenly distributed and at such a maximum distance around the object to be protected that the next-positioned drone has enough time to be able to reach the possible trajectory of the target.
  • eight drones can protect an object with an area of 250,000 m 2 .
  • the drones are evenly distributed on a circular path with a radius of 750 m around the object. This results in a distance of just under 600 m between the individual drones. To intercept the target, a drone therefore only has to cover a distance of approx. 300 m.
  • the drones are arranged around the object with a radius of less than 1 km.
  • the drones are at a distance of less than 1000 m, in particular less than 800 m, to the neighboring drone, preferably less than 600 m, which means that the drones only have to travel a short distance from the flight path of the target.
  • the drones are arranged on a circular path or on a spherical segment around the object so that the object is closely protected. It is particularly advantageous that the multicopters can hover on the spot and thus always assume the optimal defensive position.
  • the explosive charge arrangement can in particular have a shaped charge.
  • the explosive charge arrangement can alternatively or additionally have a fragmentation charge.
  • An explosive charge arrangement with only one shaped charge or only one fragment charge can be used as the effector.
  • the explosive charge arrangement has both a shaped charge and a fragment charge. Either a shaped charge, a projectile-forming charge, a fragment-forming charge or a combination of these charges can be ejected through the explosive charge arrangement.
  • the drones each have a fuselage and a gimbal, the explosive charge arrangement being connected to the fuselage of the drone by means of the gimbal. In this way, the explosive charge arrangement can be well aligned with the target in the flyby.
  • the flight path of the target is calculated in advance and the next positioned drone of the intervention system is steered towards the flight path of the target.
  • the drones of the intervention system are preferably remote-controlled by means of a command and control system. Alternatively, the drones can also be designed to be self-steering.
  • the drone can then be steered onto or close to the flight path.
  • the target is set by means of the explosive charge arrangement, ie by means of the effector fights.
  • the drone can preferably be on the flight path in front of the target or next to the target when the target is flying past.
  • a detonator of the target is preferably targeted in a targeted manner, the detonator of the target generally being arranged at the head of the RAM target.
  • the drone is preferably positioned on the trajectory of the target.
  • the drones each have at least one sensor for final phase control of the drone.
  • the drones preferably have several different sensors such as TV cameras, radar, lidar and / or IR sensors. These sensors are directed upwards towards the sky on the drone's fuselage when the drone is hovering, so that during a fast flight with a tilted fuselage, the sensors are directed towards the target in the direction of flight.
  • the at least one sensor is oriented in the direction of a rotor axis or at an acute angle to the rotor axis of the drone, so that the target can be detected with the sensor or sensors even during rapid acceleration.
  • the drone's sensors are used in particular for final phase control when the target flies by.
  • Fig. 1 and 2 an intervention system 1 with several drones 2 is shown.
  • the drones 2 are here arranged around an object 3 to be protected.
  • the object 3 to be protected is protected against attacks with C-RAM targets 4 by means of the intervention system 1.
  • a rocket 4 is shown here as an example for a C-RAM target 4.
  • the intervention system 1 is also suitable for protecting the object 3 against attacks by third-party drones (not shown).
  • the drones 2 each have an effector 5, the effector 5 being formed by an explosive charge arrangement 5.
  • the drones 2 are designed as multicopters.
  • the drones 2 accordingly have several propellers 6.
  • the drones 2 are initially ready to take off or are already positioned around the object 3 to be protected while floating in a standby mode.
  • the next positioned drone 2 of the intervention system 1 is steered to a pre-calculated trajectory of the target 4.
  • the target 4 is fought by means of the explosive charge arrangement 5 (cf. Fig. 2 ).
  • the drone 2 can preferably be on the flight path in front of the target 4 when fighting the target 4 or next to the target 4 when the target 4 is flying past.
  • the drones 2 of the intervention system 1 are preferably controlled by means of a command-and-control system (not shown) remotely. In an alternative embodiment, the drones 2 can also be designed to be self-steering.
  • the drones 2 also have various sensors 7, such as a TV camera, radar, lidar or IR sensors. These sensors 7 are arranged on a fuselage 8. When a target 4 is approaching, in particular the drone 2 closest to the predicted flight path of target 4 is accelerated in the direction of the flight path of target 4. With such a strong acceleration it can happen that the drones 2 with their propeller axes are directed essentially in the direction of flight. Here it is advantageous if the sensors 7 are also directed in the direction of flight of the drone 2.
  • the sensors 7 are preferably aligned at an acute angle or parallel to the propeller axes.
  • the sensors 7 can therefore preferably be pivoted in the direction of the propeller axes by means of corresponding joints.
  • the fuselage 8 is inclined relative to the direction of flight.
  • the sensors 7 are used in particular for final phase control of the drone 2 shortly before the target 4 flies past.
  • the drones 2 hover in particular evenly distributed at such a maximum distance around the object 3 to be protected, so that the next-positioned drone 2 has enough time to reach the possible trajectory of the target 4.
  • the distance between a drone 2 and its neighboring drones 2 is preferably less than 1 km, in particular less than 800 m, in particular approximately 600 m. It is possible here to arrange the drones 2 on a circle or a hemisphere with a diameter of 1.5 km around the object 3 to be protected.
  • the drones 2 are not only arranged on a circular path, but also cover a spherical segment around the object 3 to be protected.
  • the drones 2 can each be arranged at a distance of approximately 600 m, with eight drones 2 being distributed over the corresponding circle. With these eight drones 2, the object 3 with an area of 250,000 m 2 can be protected. To intercept a target 4, one of the drones 2 therefore only has to cover a distance of about 300 m.
  • the drones 2 and the intervention system 1 have the advantage that the drones 2 can be steered and are inexpensive. Object protection, for example of buildings or vehicles, is made possible by using a network of drones 2.
  • the explosive charge arrangement 5 is connected to the fuselage 8 preferably via a gimbal 9.
  • the gimbal 9 is essentially arranged in the center of gravity of the drone 2 with a horizontal alignment of the drone 2.
  • the Gimbal 9 can be formed by a cardanic suspension or mounting, that is to say mounting in two planes with bearings arranged at right angles to one another. This special arrangement and a balanced center of gravity make it possible for the explosive charge arrangement 5 to pivot about several axes.
  • the explosive charge arrangement 5 is arranged on an underside of the fuselage 8 of the drone 2.
  • the explosive charge arrangement 5 can either have a shaped charge 10, a projectile-forming charge, a fragment-forming charge 11 or a combination of these charges.
  • the explosive charge arrangement 5 has a shaped charge 10 and a fragmentation charge 11.
  • the explosive charge arrangement 5 is designed such that the shaped charge 10 and the fragmentation charge 11 can emerge in a lateral direction relative to the rotor axis. Because the hollow charge 10 and the fragmentation charge 11 act transversely to the direction of the rotor axes, targets 4 can be fought very well in flyby.
  • the shaped charge 10 and the fragmentation charge 11 are arranged within a housing 12.
  • the hollow charge 10 and the fragmentation charge 11 are each assigned a separate explosive 13, 14.
  • the explosive 13 has a greater detonation speed than the explosive 14.
  • Both explosives 13, 14 are ignited by means of a detonator (not shown) at the base of the hollow charge 10. Due to the different detonation speeds of the explosives 13, 14, the shaped charge jet (not shown) can exit completely before the fragmentation charge 11 detonates and exits. In this way an interaction between the two detonations can be avoided.
  • the shaped charge 10 has a metal insert 15 in the form of a shaped charge cone 15.
  • the shaped charge cone 15 preferably has copper or is made of copper.
  • the axis of symmetry (not shown) of the shaped charge cone 15 is also oriented here in a lateral direction relative to the rotor axis.
  • the housing 12 is in particular cylindrical, the gimbal 9 preferably being centered on a cover 16 is attached.
  • the shaped charge 10 and the fragmentation charge 11 point towards the cylindrical wall 17 of the housing 12.
