Device for initiating a fuse equipping a rotating projectile

Abstract

Abstract Translated from French L'INVENTION CONCERNE UN DISPOSITIF POUR LA MISE A FEU D'UNE FUSEE SERVANT A L'AMORCAGE D'UN PROJECTILE EN ROTATION, COMPRENANT UNE SOURCE D'ENERGIE ELECTRIQUE, AU MOINS UN CAPTEUR DU RAYONNEMENT INFRAROUGE EMIS PAR UNE CIBLE EN MOUVEMENT RELATIF PAR RAPPORT AU PROJECTILE, DES MOYENS ELECTRONIQUES DE TRAITEMENT DU SIGNAL DELIVRE PAR LE CAPTEUR, DES MOYENS EXPLOITANT LE SIGNAL AINSI TRAITE POUR LA MISE A FEU DE LADITE FUSEE. LE DISPOSITIF EST CARACTERISE EN CE QUE LESDITS MOYENS ELECTRONIQUES DE TRAITEMENT DU SIGNAL DELIVRE PAR LE CAPTEUR COMPRENNENT: -UN ETAGE AMPLIFICATEUR 11 EN REGIME BLOQUE TRAITANT LES BREVES IMPULSIONS EMISES PAR LE CAPTEUR 10 EN ROTATION, -UN CIRCUIT DIFFERENCIATEUR DE MISE EN FORME DU SIGNAL ANALOGIQUE DONNE PAR L'AMPLIFICATEUR, COMPORTANT UN ETAGE LIMITANT LA DUREE DESDITES IMPULSIONS, UN ETAGE 12 MEMORISANT SUCCESSIVEMENT CHACUNE DES IMPULSIONS RECUES ET UN ETAGE 13 COMPARANT LA DERNIERE IMPULSION RECUE A L'IMPULSION PRECEDENTE MEMORISEE, ET TRANSMETTANT UN SIGNAL AUX MOYENS DE MISE A FEU 14 DE LADITE FUSEE DES QUE L'AMPLITUDE DE LA DERNIERE IMPULSION RECUE EST INFERIEURE OU EGALE A CELLE DE L'IMPULSION PRECEDENTE MEMORISEE. APPLICATION AUX FUSEES DE PROXIMITE A INFRAROUGE POUR MUNITION DE MOYEN CALIBRE. The invention relates to a device for the ignition of a rocket serving to initiate a rotating projectile, comprising a source of electrical energy, at least one sensor of the infrared radiation emitted by a moving target by RELATION TO THE PROJECTILE, ELECTRONIC MEANS FOR PROCESSING THE SIGNAL DELIVERED BY THE SENSOR, MEANS USING THE SIGNAL THUS TREATED FOR THE FIRE OF THE SAID ROCKET. THE DEVICE IS CHARACTERIZED IN THAT THE SAID ELECTRONIC MEANS FOR PROCESSING THE SIGNAL DELIVERED BY THE SENSOR INCLUDE: - AN AMPLIFIER STAGE 11 IN LOCKED CONDITION PROCESSING THE BRIEF PULSES EMITTED BY THE SENSOR 10 IN ROTATION, - A DIFFERENTIATOR CIRCUIT FOR THE START-UP SIGNAL ANALOGUE GIVEN BY THE AMPLIFIER, INCLUDING A STAGE LIMITING THE DURATION OF SAID PULSES, A STAGE 12 SUCCESSIVELY STORING EACH OF THE PULSES RECEIVED AND A STAGE 13 COMPARING THE LAST PULSE RECEIVED TO THE PREVIOUS PULSE STORED, AND TRANSMITTED TO THE LAST PULSE RECEIVED. FIRE 14 OF THE SAID ROCKET AS SOON AS THE AMPLITUDE OF THE LAST PULSE RECEIVED IS LESS OR EQUAL TO THAT OF THE PREVIOUS PULSE STORED. APPLICATION TO PROXIMITY INFRARED ROCKETS FOR MEDIUM CALIBER AMMUNITION.
