Abstract

Dispositif destiné à neutraliser la nutation d'engins spatiaux. Le dispositif destiné à neutraliser la nutation selon la présente invention comporte un arbre 1 entraîné par un moteur 5, un volant 6 monté de façon orientable sur l'arbre de façon à pouvoir s'incliner dans toutes les directions, des zones espacées 21, 22 n'entrant pas en contact, portées respectivement par l'arbre et le volant, au moyen desquelles un couple qui est une fonction monotone de la vitesse d'inclinaison est transmis à l'arbre puis à l'engin spatial, de façon à réaliser l'amortissement de la nutation. Application à des engins spatiaux animés d'un mouvement de rotation autour d'eux-mêmes (spin).Device intended to neutralize the nutation of spacecraft. The device intended to neutralize nutation according to the present invention comprises a shaft 1 driven by a motor 5, a flywheel 6 mounted in an orientable manner on the shaft so as to be able to tilt in all directions, spaced areas 21, 22 not coming into contact, carried respectively by the shaft and the flywheel, by means of which a torque which is a monotonic function of the tilt speed is transmitted to the shaft and then to the spacecraft, so as to achieve damping of nutation. Application to spacecraft animated by a rotational movement around themselves (spin).
