Definitions

  • Sausage-shaped practice targets towed by aircraft are currently used but these targets are unable to simulate realistic flight behaviour, evasive tactics, etc.
  • These targets can be provided with a hit indicator (in reality a device measuring the miss distance), which records the number of shots within various zones from the indicator.
  • the present invention designated the Ripan system, solves the above problems.
  • Condition 1-3 led to the choice of radio-controlled miniature aircraft as a preferred carrier for sensing and indicating members with signal-processor between.
  • Condition 4 is fulfilled by means of pyrotechnical visual indication, flash, fitted on the aircraft. An electric flash or radio-transmission to a "display" on the ground is also feasible.
  • condition 5 enables fulfilment of condition 6.
  • the target size can be varied by giving the sensor unit a variable sensitivity threshold.
  • a microphone is selected which senses the pressure surge from a projectile passing at supersonic speed. The amplitude of this pressure surge is proportional to the distance and different thresholds can therefore be selected for this.
  • the miniature aircraft may thus constitute a "virtual" target differing in size from one time to another. The target is "virtual" since the visible target the soldier aims at is always the miniature aircraft.
  • a buffer for the number of registrations is also included in the signal processor, thus enabling the number of hits for achieving destruction to be varied. Varying degrees of difficulty are thus possible.
  • “Ripan” comprises the following main components:
  • the sensor 1 may be electromagnetic in order to avoid this limitation.
  • the signal processor is a unit 2 in which the sensitivity threshold for the microphone and the number of recorded "hits" required for destruction are set.
  • the processor 2 When the pre-set number of recorded "hits" has been reached, the processor 2 emits a signal which trips an indication.
  • the indicator unit 3 may consist of a number of pyrotechnical cartridges giving a powerful reddish flash to ensure good visibility.
  • the cartridges are disposed of after use, and are replaced by new ones.
  • the miniature aircraft is radio-controlled and can be guided from the ground both with respect to direction and speed.
  • the plane needs no special start ramp, but is thrown into the air by the "pilot's" assistant.
  • the equipment consists of five units:
  • the signal-processor, decoder/detonator unit and battery unit are combined to form a hit indicator.
  • the measuring microphone and pyro-unit are connected to the hit indicator by cabling provided with a contact device.
  • the hit indicator is based on the principle that a pressure wave (supersonic bang) is generated around a projectile travelling at supersonic speed.
  • the amplitude of the pressure wave decreases as the distance from the passing projectile increases.
  • the pressure wave is picked up by a measuring microphone and its signal is transmitted to the signal processor.
  • the in-coming signal is detected and processed in the signal-processor.
  • the analog signal is then converted to digital form. (8 bits parallel.)
  • the digital information is then transmitted to the decoder/detonator.
  • the digital information which is proportional to the amplitude from the supersonic bang, is converted in the decoder to a new digital form corresponding to 15 distance zones around the microphone.
  • a pre-set zone is then selected and passed on to a programmable counter which counts the number of detected hits within the selected zone.
  • the counter is adjustable between 1 and 15. When the correct number of hits is reached a firing pulse will be generated to a pyrotechnical charge.
  • the pyro-unit consists at present of 10 pyrotechnical charges. These are triggered electrically. Selection is performed and the requisite firing pulse generated in the detonator which forms an integral part with the decoder.
  • All units are supplied with current in any suitable manner, such as from a separate battery unit.
