Definitions

  • the invention relates to an interception device for flying objects, according to the preamble of claim 1.
  • FR-PS 859 282 which comes closest to the subject of the application, describes interception devices in the form of net-like structures which are brought into the trajectory of the object to be controlled by means of a carrier projectile and are deployed there preferably by centrifugal force.
  • interception devices in the form of net-like structures which are brought into the trajectory of the object to be controlled by means of a carrier projectile and are deployed there preferably by centrifugal force.
  • small, evenly distributed flyweights are arranged on the net.
  • the vertical falling speed of the interception device can be slowed down, for example, by several small parachutes, ie by aerodynamic resistance bodies, which results in a longer dwell time in the air and thus a higher probability of being hit.
  • the possible applications should also extend to land and water vehicles.
  • Comparable interception devices are described in EP-OS 0 175 914, in which at least one projectile is moved in the direction of an object to be combated, and in the vicinity of the object, a parachute, tennis net, accordion or octahedral element is ejected and unfolded over a large area becomes.
  • Shock-absorbing devices are provided between the projectile (s) and the element in order to prevent damage to the element or separation from the projectile when it is unfolded.
  • DE-OS 24 15 288 describes air and water barriers in the form of missiles deployed with missiles. In the case of air locks, the ropes are prevented from falling too quickly by parachutes, balloons, wings etc.
  • DE-PS 37 22 420 deals with interception devices for combating helicopters in the form of strands or ropes. which are deployed in bundles or networks and should collide with the main or control motor of the helicopter. The goal is clearly to destroy the helicopter by crashing.
  • the object of the present invention is to provide an interception device for flying objects, in particular manned aircraft, which is capable of effectively obstructing or preventing enemy flight missions, without the use of destructive or fatal means.
  • the essence of the invention is that the interception device neither seriously damages nor destroys the affected flying object, but negatively influences its flight properties, in particular its speed and maneuverability, by means of aerodynamic active bodies, so that it cannot continue its mission in a planned manner.
  • This disability or disturbance is limited in time by the interception device itself being destroyed at a selectable point in time, so that the flying object can return to its airfield unhindered and land safely.
  • the interception device must be destroyed at the latest when dangerous flight conditions, such as insufficient ground clearance or spin, occur.
  • the invention is less or not suitable for the interception of helicopters (rotary wing aircraft) and propeller aircraft, since the danger of a standstill or destruction of the rotors or propellers would be too great, which would result in an immediate emergency landing or a crash.
  • Subclaims 2 to 7 contain preferred configurations of the interception device according to claim 1.
  • the expected flight ban of the aircraft 2 in Fig. 1 is marked with a horizontal arrow and - in its extension - with a dashed line.
  • This trajectory crosses the trajectory of a missile 3 coming from the bottom right, which carries the interception device 1 as a payload.
  • the interception device 1 is released, e.g. by explosive self-dismantling of the missile 3, and unfolded. Unfolding can also be carried out or supported, for example, by additional small solid rockets or by spring-elastic elements such as wires, springs, etc.
  • the interception device can take on a two-dimensional as well as a spatial extension, e.g.
  • High-strength plastic fibers are the basic material for the structure of the interception device, since they are light, tear-resistant, elastic and flexible, thereby reducing the risk of damage to the aircraft to a minimum. Furthermore, they are relatively easy and quick to destroy thermally or chemically if necessary.
  • FIG 2 shows the moment when the net-like interception device 1 is caught on the aircraft 2, containers 4 being indicated, in which aerodynamic resistance bodies are located, here in the form of small parachutes 5.
  • resistance bodies are deployed automatically or remotely, in their entirety or selectively.
  • a selective, that is, spatially and temporally staggered actuation is more favorable with regard to a limitation of the deceleration values of the aircraft and a targeted influencing of its aerodynamics.
  • Asymmetric configurations are also conceivable, which force the aircraft into a curve or a descent.
  • There are countless possibilities with regard to the type and operation of the resistance bodies e.g. Balloons, air bags, parachutes, ribbons, foam bodies etc., whereby the operation is most easily done by the air flow.
  • compressed gases, liquid foams, etc. can also be carried.
  • FIG. 3 shows the aerodynamically disturbed state of the aircraft 2 with the parachutes 5 unfolded.
  • negotiations can be carried out with the crew or their command post, and only then if a termination of the mission has been assured or a continuation no longer makes sense the interception device 1 is destroyed and the aircraft 2 is released. Destruction may also be necessary if dangerous flight conditions occur, such as near the ground, dive, spin etc.
  • a self-destruction device can be integrated into the interception device, which is activated via remote control.
  • This can e.g. chemical, electromechanical, electromagnetic, electrothermal or pyrotechnic.
  • the structural material of the interception device is preferably locally selectively destroyed by dissolving, melting, tearing, cutting, etc.
  • the interception device can be destroyed by external influences, preferably by means of chemical reagents or high-energy radiation.
  • the former are, for example, in the form of fog or clouds by means of an aircraft, missile, grenade or other carrier in front of the The affected aircraft are deployed and must be such that they attack the interception device but not the aircraft structure.
  • High-energy rays are, for example, laser beams which are directed onto the interception device from a suitable carrier or from the bottom.
