Definitions

  • the present invention relates to a multi-channel connector and a method of communicating pyrotechnic orders.
  • the invention applies to the pyrotechnic field and in particular to a multichannel connection making it possible to distribute and receive pyrotechnic orders using a detonating cord, in particular in a logic comprising several pyrotechnic chains.
  • connections which can be of several types depending on the functions they have to perform. These are straight or two-way fittings, three-way fittings arranged in a Y or star configuration, four-way fittings. These connections make it possible to multiply the pyrotechnic order only by two or three. Furthermore, these affect the reliability of the system by the number of interfaces requested.
  • This multichannel connection comprising a detonating cutting cord is characterized in that said detonating cutting cord is in the form of a dihedral, enclosed in a support provided with openings, in a number equal to the number of communication channels, accomplishing from a pyrotechnic signal, a plurality of various terminal functions.
  • each communication channel comprises, opposite the corresponding openings, a pyrotechnic relay connected to a communication sheath.
  • the subject of the invention is also a method of communication of pyrotechnic orders making it possible to distribute and receive pyrotechnic orders in a logic comprising several pyrotechnic chains intended to perform multiple terminal functions on board aircraft, missiles and launchers. This process is characterized in that such communication takes place using the hollow charge effect of a detonating cutting cord.
  • the communication of a pyrotechnic signal to a pyrotechnic chain is effected by an input situated in the acute angle of the dihedral of the cutting cord and by an output situated also in this angle acute.
  • This communication of the pyrotechnic signal can also be carried out by an input located on the back of said cord.
  • a pyrotechnic signal from a cord is reversible, that is to say that the signal can arrive indifferently by one of the twenty channels, such as channel 20 represented by the arrow F "and can be retransmitted to the nineteen others materialized by the arrows F 2.
  • the signal can be triggered at one of the ends of the said cord as represented by the arrow F 3 , or by the back 10 of the said cord as represented by the arrow Fg. cord can then retransmit the pyrotechnic signal either at the other end of said cord represented by arrow F 4 , or on the side of the shaped charge as indicated by arrows F 2. But this cord does not retransmit the signal by the back of said cord 10.
  • the communication of the pyrotechnic signal to the different communication channels can be more or less rapid depending on the location of the ignition. If the start signal is given at one end of the string, as represented by arrow F 3 , or at track 20, as represented by arrow F , the transmission of the pyrotechnic signal will be so to speak instantaneous for channels 21, 22 ..., but this transmission, however rapid, will spread over time for the following channels. This allows the sequence of terminal functions to be adjusted as desired. It is the same for firing by the back of the cord, firing which can take place anywhere on the back of the cord, depending on the desired effects.
  • the example chosen concerns the separation and removal of the cap from a ballistic device.
  • an electrical command center 50 has been used, first controlling two arming boxes 60 and 70 referenced in FIG. 4a.
  • the first box 60 organizes the circular cut between the equipment box on the top floor of the machine and the cap of the latter.
  • the box consists of an electric actuator 61 for locking and / or unlocking, a barrier located inside the box 62, between primer-detonators 63 and a pyrotechnic chain 64. This comprises two paths: a normal route and an emergency route leading to a cutting cord 65a.
  • the primers are loaded with primary explosive.
  • the electrical control center controls two impellers 80a and 90a allowing the two half-caps to be moved away. Each impeller fixed on each of these leaves with it. These impellers consist of an electric actuator 81 or 91 for locking and / or unlocking, a barrier arranged inside the impeller 82 or 92, between a igniter 83 or 93 and an impeller nozzle 84 or 94.
