Abstract

La ligne de visée 22, 23 est définie par un miroir principal 12 lié à un cadre 11 monté à un cadran suivant les axes de tangage et d'azimut du véhicule équipé du viseur. Le recalage du miroir 12 est assuré par un gyroscope 17 à deux degrés de liberté suivant les axes précités, actionnant un moteur d'azimut 14 et un moteur de tangage 30. Une masse équilibrée 40, constituée par exemple par un volant, mobile suivant l'axe de tangage, est reliée au moteur de recalage 30 du miroir 12 par une transmission inversée le rapport des moments d'inertie des masses mobiles, et le rapport de démultiplication des mouvements angulaires, sont tels que le couple de recalage demandé au moteur 30 se trouve sensiblement réduit Application aux viseurs gyroscopiques stabilisés, pour en améliorer la sensibilité en réduisant l'importance des moteurs d'asservissementThe line of sight 22, 23 is defined by a main mirror 12 linked to a frame 11 mounted to a dial along the pitch and azimuth axes of the vehicle equipped with the sight. The adjustment of the mirror 12 is ensured by a gyroscope 17 with two degrees of freedom along the aforementioned axes, actuating an azimuth motor 14 and a pitch motor 30. A balanced mass 40, constituted for example by a flywheel, movable along l The pitch axis is connected to the adjustment motor 30 of the mirror 12 by an inverted transmission the ratio of the moments of inertia of the moving masses, and the gear ratio of the angular movements, are such that the adjustment torque requested from the motor 30 is significantly reduced Application to stabilized gyroscopic sights, to improve sensitivity by reducing the importance of servo motors
