Definitions

  • the invention relates to a device for the rescue of a hit display sensor, which is detachably arranged in a serving for displaying air targets and provided with a rescue system with a parachute and a tow rope linkage for fastening a tow rope.
  • Such target bodies are well known and are used in various air forces. These tow target bodies are pulled behind an aircraft during an air / air practice shooting with barrel weapons to represent an air target by means of a tow rope.
  • the towed target body essentially consists of a central stringer with smaller or larger wings arranged thereon and a hit display sensor arranged thereon. Both devices, tow Target body and hit display sensor, are so far as one-way or loss devices designed. This means that either the towing target is separated from the towing aircraft after use and is no longer recovered, or it glides to the ground with a parachute.
  • a salvage system for towed flying targets which consists of a parachute
  • the triggering device is effective when the tension of the tow rope is released.
  • the end of the tow rope attached to the target missile is electrically conductive and has electrical contact with a control circuit in the target missile.
  • At its contour there is an electrically conductive contact ring that is insulated from its skin.
  • the object of the invention is to provide a device with which the relatively small, light and costly hit indicator sensor with associated electronics can be separated from the large, heavy and often severely destroyed and useless for further use and can be recovered as a reusable device.
  • the advantage of the invention is that the hit display sensor can be separated from the towing target body automatically by mechanical activation of the salvage electronics as well as by radio-electronic activation by means of reception and salvage electronics. This makes it possible to separate the hit display sensor together with the recovery system from the towing target body so that the sensor remains undamaged after landing or watering and can be reused for a new use. This results in a considerable saving in devices to be replaced and the associated considerable costs.
  • the salvage system with the salvage and / or reception electronics arranged in it is attached to the towing target body by pyrotechnic separating elements, for example explosive screws or explosive rivets.
  • pyrotechnic separating elements for example explosive screws or explosive rivets.
  • the tow rope is overtaken by the tow target body because of its relatively greater air resistance to the tow target body and its lower mass. It attaches itself to the top of the towed target body, its position to the articulation point being defined.
  • the contact circuit Located at the pivot point the contact circuit in the form of a microswitch.
  • a rotatable contact bar which is arranged on the towing target body and connected to the tow rope and its linkage, serves as a signal generator, which is automatically switched by a touch sensor.
  • the resulting activation of the salvage electronics gives the ignition impulses for cutting through the brine fractures of the pyrotechnic separating elements.
  • the salvage system together with the hit display sensor, separates from the tow target under the influence of air resistance.
  • a parachute system stowed in it is pulled out and released.
  • the rescue electronics attached to the parachute or hanging with the hit display sensor slide thereon at a predetermined rate of descent to the ground. After recovery, both the hit display sensor and the recovery electronics can be processed and reused for further use.
  • the recovery system is equipped with additional receiving electronics.
  • the resulting commanded salvage of the hit display sensor with electronics becomes necessary if the device is not suitable for dropping Area is available or there are technical difficulties.
  • the devices must be flown overland and sent from a command transmitter installed on the ground or on board the towing aircraft to the salvage electronics in the towing target body.
  • a signal is sent as an ignition pulse to the pyrotechnic separating elements via an antenna installed in the salvage system, as well as receiving electronics and a decoder, whereupon these are ignited and the subsequent separation and salvage process proceeds as described above.
  • a separate power supply e.g. battery
  • the recovery system works completely autonomously. It is therefore not necessary to change the shape of current hit display sensors.
  • the tow target body 1 shows a towed target body 1 with a salvage system 2 in a side view and in a view from above.
  • the tow target body 1 has on its upper side a tow rope lowering 3, to which a tow rope 4 pulled by an aircraft, not shown in the figure, is connected.
  • the recovery system 2 is arranged within a housing 5 and a hit indicator sensor 6 is arranged thereon. Both are attached to the drag target body 1 by means of pyrotechnic separating elements 7 (for example explosive screws or rivets provided with predetermined breaking points).
  • the recovery system 2 contains, among other things, recovery and reception electronics 8, 8 'consisting of antenna, receiver and decoder, a power supply 9 (eg battery), a parachute system 10, a contact circuit 11 and a touch sensor 12 designed as a signal transmitter Part of the housing 5, in towing or.
  • the parachute system 10 is firmly connected together with the rescue and / or reception electronics 8 and power supply 9 arranged in the rear area together with the hit display sensor 6.
  • the outer contour of the salvage system 2 or its housing 5 and that of the hit display sensor 6 are matched to one another.
  • the touch sensor 12, which is designed as a signal transmitter, is arranged near the tow linkage 3, with which the bearing of the tow rope 4 is determined relative to the tow target body 1.
  • a contact strip 13 is arranged on two thimbles (not shown in more detail) on which the tow rope 4 hangs. After the tow rope 4 has been cut off, the contact strip 13 rotates when the tow rope 4 remains on the touch sensor 12 and triggers the activation for the recovery process.
  • FIG. 2a shows the towed target body 1 in the towed position
  • FIG. 2b the cut tow rope 4 is retracted due to the undertaking of the towed target body 1 and its air resistance fall and lies with the contact strip 13 on the touch sensor 12 ( Figure 2c).
  • the pyrotechnic separating elements 7 were ignited and the detection system 2 together with the hit display sensor 6 were released from the towed target body 1, and the parachute 14 was released.
  • FIG. 2d the salvage system 2 and the hit display sensor are suspended on the parachute 14 to the ground.
  • the target body 1 is lost.
  • the process is automatic.
  • Figures 3a to c show the salvage procedure after a command given by the aircraft or from the ground.
  • the tow rope 4 is not cut on the aircraft.
  • the separation process is the same as that previously described; the devices 2, 6, 8 ⁇ , 10 slide down on the parachute.
  • FIG. 4 shows a switching arrangement of the recovery system 2 for automatic (according to FIGS. 2a to d) and commanded (FIGS. 3a to c) activation and triggering of the parachute system 10 (FIGS. 2 and 3).
  • the command signal arrives via the antenna 15 in the receiving or triggering electronics 8, 8 ⁇ , in which (if the tow rope 4 is cut in FIG. 3) there is also a signal from the rope layer contact sensor 12 is entered and from where the ignition pulse is delivered to the pyrotechnic separating elements 7.
  • the salvage system 2 can be reduced.
  • the use of the command / receive electronics can be dispensed with.
  • the contact circuit 11, the touch sensor 12 and the contact strip 13 are superfluous if it is certain that a rescue of the hit display sensor 6 and the other devices should be initiated only by a radio command.
