METHOD AND DEVICE FOR BOOST CONTROL OF PROJECTILE
(FR)
PROCEDE ET DISPOSITIF DE REGULATION DE LA PRESSION D'ADMISSION D'UN PROJECTILE
Abstract:
(EN)
A method for boost control is based on measuring the angular speed of the line of sight during approach of the target within the zone of its precise direction finding by the self-directing head (1) and on influencing the projectile by a jet reaction correcting force in a plane perpendicular to the longitudinal axis of the projectile so as to take up the accumulated miss. The jet reaction correcting force is switched on during the approach of the projectile to the target at the moment of reaching the threshold value of the angular speed of the observing line of sight depending on the speed of approach. Simultaneously with the switching of the correcting force bank turning of the projectile is effected until liquidation of the phase error, in the radial plane of the projectile, between the miss and the correcting force. The duration of influencing the trajectory by the correcting force is regulated. Its action is stopped at the moment of zeroing of the angular speed of the line of sight which corresponds to the moment of zeroing of the miss. A device for implementing the method comprises, mounted on the projectile and interconnected by an electric communication circuit, a self-directing head (1), a control unit (2) and a means (5) for trajectory correction consisting of a gas generator with multiple nozzles (8, 8') covered with plugs and located in radial planes, so that to each nozzle (8) of the gas generator corresponds an opposite symmetrically located reverse nozzle (8').
(FR)
Un procédé de régulation de la pression d'admission se base sur la mesure de la vitesse angulaire de la ligne de visée pendant l'approche vers la cible, à l'intérieur de la zone de son repérage précis, au moyen de la tête autodirectrice (1), et sur l'influence d'une force de correction par jet dans un plan perpendiculaire à l'axe longitudinal du projectile s'exerçant sur celui-ci de manière à compenser les erreurs cumulées. La force de correction par jet est déclenchée pendant l'approche du projectile vers la cible au moment où est atteinte la valeur de seuil de la vitesse angulaire de la ligne de visée, en fonction de la vitesse d'approche. Au moment où se déclenche la force de correction, le projectile effectue un virage jusqu'à suppression de l'erreur de phase, dans son plan radial, entre la mauvaise trajectoire et la force de correction. La durée de l'influence exercée sur la trajectoire par la force de correction est régulée. Son action est interrompue lorsque la vitesse angulaire de la ligne de visée est nulle, laquelle correspond au moment où l'erreur de trajectoire est nulle. Un dispositif de mise en ÷uvre du procédé comprend, montés sur le projectile et interconnectés par un circuit de communication électrique, une tête autodirectrice (1), une unité de commande (2) ainsi qu'un moyen de correction de trajectoire constitué d'un générateur de gaz à tuyères multiples (8, 8') pourvues d'obturateurs et situées dans des plans radiaux, de manière qu'à chaque tuyère (8) du générateur de gaz corresponde une tuyère (8') symétriquement et diamétralement opposée.
