Abstract

L'INVENTION CONCERNE UN DISPOSITIF PERMETTANT DE PRODUIRE DES DONNEES INERTIELLES, STRUCTURELLES ET AERODYNAMIQUES A PARTIR DE FLEXIONS DE LA STRUCTURE D'UN VEHICULE VOLANT QUI SONT INDUITES PAR LES FORCES AGISSANT SUR LA STRUCTURE. LE DISPOSITIF COMPREND DES CAPTEURS 12 REPARTIS SUR LA STRUCTURE ET PRODUISANT DES SIGNAUX PROPORTIONNELS A LA DIRECTION ET A L'AMPLITUDE DES FLEXIONS DE LA STRUCTURE APPARAISSANT EN RESULTAT DE L'APPLICATION DE FORCES. CES SIGNAUX SONT TRAITES PAR UN CALCULATEUR 16 QUI DETECTE ET ISOLE DES SIGNAUX SONT TRAITES PAR UN CALCULATEUR 16 QUI DETECTE ET ISOLE DES SIGNAUX EN PROVENANCE DE CAPTEURS CHOISIS ET TRANSFORMENT LES SIGNAUX CHOISIS EN DONNEES UTILES. LES CAPTEURS 12 PEUVENT MESURER DES FLEXIONS DE 10 RADIAN DANS UNE GAMME DE FREQUENCE DE 0 A 10000HZ. L'INVENTION S'APPLIQUE A TOUS LES TYPES DE VEHICULES VOLANTS ET AMELIORE LA NAVIGATION PAR INERTIE, LA COMMANDE DE VOL OU DE TIR, LA COMMANDE DU MOTEUR ET LA DETECTION DE DEFAUTS STRUCTURELS.THE INVENTION RELATES TO A DEVICE ALLOWING TO PRODUCE INERTIAL, STRUCTURAL AND AERODYNAMIC DATA FROM BENDING OF THE STRUCTURE OF A FLYING VEHICLE WHICH ARE INDUCED BY THE FORCES ACTING ON THE STRUCTURE. THE DEVICE INCLUDES SENSORS 12 DISTRIBUTED OVER THE STRUCTURE AND PRODUCING SIGNALS PROPORTIONAL TO THE DIRECTION AND TO THE AMPLITUDE OF THE BENDINGS OF THE STRUCTURE APPEARING AS A RESULT OF THE APPLICATION OF FORCES. THESE SIGNALS ARE PROCESSED BY A COMPUTER 16 WHICH DETECTS AND ISOLATES SIGNALS ARE PROCESSED BY A COMPUTER 16 WHICH DETECTS AND ISOLATES SIGNALS COMING FROM SELECTED SENSORS AND TRANSFORMING THE SELECTED SIGNALS INTO USEFUL DATA. THE SENSORS 12 CAN MEASURE BENDING OF 10 RADIAN IN A FREQUENCY RANGE FROM 0 TO 10000HZ. THE INVENTION APPLIES TO ALL TYPES OF FLYING VEHICLES AND IMPROVES INERTIAL NAVIGATION, FLIGHT OR FIRE CONTROL, ENGINE CONTROL AND DETECTION OF STRUCTURAL FAULTS.
