Title (EN) METHOD AND ARRANGEMENT FOR PROGRAMMING SHELLS
(FR) PROCEDE ET AGENCEMENT DE PROGRAMMATION D'OBUS
Abstract: front page image
(EN)The present invention relates to a method and an arrangement in order to make possible, inshell-firing weapons with rifled barrels (1) made of steel, inductive transmission of programming data from a programming device (11) connected to the weapon to a programmable time fuse (21) arranged in the respective shell (12) while the shell (12) is situated in the cartridge chamber of the weapon. According to the invention, the steel barrel has been provided with an insert (4) made of non-magnetic material which surrounds the cartridge chamber of the weapon and which moreover cannot form a closed electrically conductive circuit around the shell and which therefore will not disrupt transmission. The electric transmitting coil (8) necessary for the inductive transmission is then arranged in a groove (7) around this insert while the shell in turn has its own internal receiving coil (18).
(FR)La présente invention propose un procédé et un agencement visant à rendre possible, dans des armes tirant des obus et munies de canons rayés (1) en acier, la transmission par induction des données de programmation depuis un dispositif de programmation (11) connecté à l'arme et à l'amorce à retardement programmable (21) disposée dans l'obus correspondant (12), ce dernier (12) se trouvant dans la chambre à cartouche de l'arme. Selon l'invention, le canon en acier est muni d'un insert (4) en matériau non magnétique, qui entoure la chambre à cartouche de l'arme et qui, de plus, ne peut pas former de circuit électrique fermé autour de l'obus et, partant, interrompre la transmission. De ce fait, la bobine électrique de transmission (8), nécessaire pour la transmission par induction, est disposée dans la gorge (7) autour de l'insert, l'obus possédant, à son tour, sa propre bobine interne de réception (18).
