Definitions

  • the invention relates to devices, for example military charges, placed in devices such as rockets, and the starting of which must take place during the flight of the device.
  • devices for example military charges
  • These devices or rockets can be launched from fixed or mobile firing stations, and in particular from a rocket launcher.
  • Certain military charges such as arrow charges, must be fired before the missile arrives at the target. Indeed, these charges project one or more projectile bursts in a manner determined in advance. For these bursts to be effective, it is necessary for the charge to be started up precisely, that is to say at a determined distance from the target. For example, with regard to the arrowheads, the latter have a maximum efficiency when they are launched at about 500m from the target, the carrier can be launched at several thousand meters from the target.
  • the machine must have time information to be able to trigger the operation of the load at the desired time.
  • the ignition of the machine is transmitted to the latter via a control wire.
  • the data relating to the timing for the start of the military charge are transmitted to the latter by means of induction coils placed both on the carrier system and on the ammunition.
  • This order transmission system has a drawback which is the need to have a carrier system equipped with such coils to be able to transmit the timing orders, when it is a question of launching an ammunition whose military load must operate in flight course. There is therefore a problem of standardization of both the carrier system and the ammunition.
  • the object of the invention is to remedy this drawback by modifying the system and the method for transmitting timing orders concerning the starting of the military charge.
  • the object of the invention is a method and a system for transmitting temporal information concerning the starting of a device, placed in a machine launched from a carrier system, the firing control of the 'machine being transmitted to him from said carrier system by means of a firing control wire, characterized in that it consists in using said control wire to transmit said information to said device.
  • the device to initiate 1 is in a device 2, such as a rocket.
  • a device 2 such as a rocket.
  • This device is launched from a carrier system 4, in this case a rocket launcher tube.
  • the timing signal for switching on the device 1 is made by means of a rangefinder 16 and a computer 3 of the carrier system.
  • the firing signal of the machine is supplied to the latter via a control wire 5, and this on the initiative of the shooter.
  • This signal for firing the machine can be formed by the front edge of a positive pulse; this signal is shown in Figure 2.
  • the signal communicated to the guided vehicle just before its ignition and which is the timing of the starting of the device, is also transmitted by the control wire 5, and not by coils placed both on the carrier system and both on the periphery of the machine. It should be noted that this timing information was previously transmitted in analog form. According to The present invention provides for transmitting this digital information, which allows the on-board computer 3 to be used when the carrier system is constituted by an aircraft, the craft then being a rocket.
  • the signal carrying the time information at the end of which the device must be triggered consists, with reference to FIG. 3, of pulses of the order of Mhz spaced apart by intervals of the order of 100 microseconds.
  • the bits have been represented with different pulse durations (for example, 100 s for the "zeros", 300 ⁇ s for the "one” but this is only an exemplary embodiment).
  • a high-pass filter 6 is used which allows the frequencies of the pulses to pass.
  • the output of this filter is applied to a memory 7 which stores the successive bits constituting the time information.
  • the control wire 5 is also applied to the input of a low-pass filter 8 which allows the frequencies of the firing pulses of the machine and of switching on to pass.
  • the output of this wire is applied to a time delay 9 which is triggered when the edge is controlled by a positive pulse as shown in FIG. 2.
  • This signal is represented in FIG. 4 and can consist of a negative pulse of a duration at least as long as that of the transmission of the digital time information.
  • This signal is applied to a trigger circuit of the electronics 10 via a diode 11 allowing only negative voltages to pass.
  • This electronic start-up circuit sensitizes the memory 7 and the time delay 9, as well as a possible clock intended for the operation of the various circuits.
  • a machine or a rocket equipped with these few elements can obviously be adapted and therefore launched by a carrier system on which there is a rangefinder and electronic circuits capable of developing the digital signal constituting the time information, and applying it to the control wire 5.
  • the device is then a military charge, and in particular, an arrow charge. It is therefore possible to adapt to different support systems such as aircraft (planes or helicopters) or rocket launchers carried by an infantryman, ammunition or devices, guided or not, such as rockets comprising the elements which have just been described. This therefore multiplies the possibilities for adapting guided vehicles carrying military loads on different support systems.
