Definitions

  • the invention relates to a receiving coil for a programmable projectile detonator with a coil core on which there is a winding.
  • a programmable projectile detonator e.g. According to EP-A-0 300 255, contains a device for setting a counter for triggering the detonator, in particular a time fuse, in the projectile after it has been fired, the counter being inductive from a transmitter coil fastened in front of the barrel of a weapon via the receiver coil located in the projectile is set with a device for measuring the muzzle velocity of the projectile in order to set the counter for triggering the time fuse as a function of the muzzle velocity, the receiving coil being wound on a coil former.
  • the receiving coil of the projectile passes through the transmitting coil attached to the weapon barrel muzzle in a relatively short time, so that there is only little time available for transmitting the information from the transmitting coil to the receiving coil. High frequencies are therefore necessary to transmit the information.
  • an insert is arranged between the coil core and the coil winding, which shields the winding against eddy current fields.
  • a thin, 0.05 mm thick steel strip is preferably inserted between a coil winding made of copper and a coil core made of aluminum. This steel strip dampens the magnetic fields of the transmitter coil so strongly that almost no eddy currents are generated in the aluminum coil core. Eddy currents also form in the steel strip, but these are considerably smaller due to the greater eddy current resistance R (fe) of the iron.
  • the receiving coil according to the invention behaves like a coil on a coil core made of steel.
  • the weapon barrel muzzle 10 is surrounded by a three-part cage 11, 12, 13, which projects beyond the weapon barrel muzzle 10.
  • a first measuring coil 14 In the middle part 12 of the cage there is a first measuring coil 14 and in the front part 13 of the cage there is a second measuring coil 15 and a transmitting coil 16.
  • Lines 17 and 18 are provided for the electrical supply of the two measuring coils 14 and 15.
  • a number of soft iron bars 19 are inserted into the three-part cage 11, 12, 13 from to shield the entire measuring system from interference from magnetic fields which only two are visible in Fig.1.
  • the transmitter coil 16 consists of a single turn 20 and a coil body 21.
  • a projectile 22 flies in the direction of arrow A through the device for measuring the initial speed and for transmitting information, ie through the two measuring coils 14 and 15 and through the transmitter coil 16 .
  • the transmitter coil consists of a single turn 20 and is relatively narrow.
  • the time t which the projectile 22 needs to travel from the coil 14 to the coil 15 is measured.
  • a timer 24 located in the projectile 22 can thus be set or "temped” so that the projectile 22 is ignited in the area of the target.
  • This time which the projectile 22 needs to reach the destination when it exits the pipe mouth 10, is transmitted in digital form from the transmitter coil 16 to a receiver coil 25 in the projectile.
  • the transmission is inductive.
  • To set the timer 24 with the desired accuracy at least twelve pulses should be transmitted from the transmitter coil 16 to the receiver coil 25. Since, as already mentioned, the projectile 22 flies through the transmitter coil 16 at a speed of approximately 1,200 meters per second, it is necessary to transmit the twelve pulses at a relatively high frequency at the correct time.
  • the correct time for sending the pulses is determined with the help of the front measuring coil 15 of the device for measuring the muzzle velocity. As soon as the projectile 22 has flown through the coil 15, the information can be transmitted from the transmitter coil 16 to the receiver coil 25.
  • the pulses pass from the receiving coil 25 via a filter 29 to a counter 32 which is connected to the timer 24.
  • a so-called ground igniter 40 is screwed into the rear end of a projectile 41 via a thread 42.
  • the individual organs of the detonator are located in the interior of a detonator housing 43, which also acts as a coil core 43 and, together with a winding 23, forms the reception coil 25 already mentioned.
  • An insulation layer 44 protects the coil against damage from the hot propellant gases.
  • the structure of the detonator is assumed to be known and is not described in more detail here.
  • an insert 45 preferably a steel strip, for example made of ferroelectric material with high permeability, is located between the winding 23 made of copper wire and the coil core 43 made of aluminum between the winding 23 and a thickness of 0.05 mm is sufficient to shield the winding 23 against an eddy current field.
  • a much thicker insert 45 made of insulating material can be used, provided there is enough space. A similar effect is achieved by the distance formed between the copper wire and the aluminum core.
