ABSTRACT:
The nutation damper comprises a closed flow path for a dense liquid, which may be a propellent and a pump for setting the liquid in periodic motion, thereby to dissipate or generate rotational energy controlled by a detector sensitive to a parameter relating to the nutation angle, according to the law of conservation of angular momentum. The principal application of the device is to the nutation damping of spinning spacecraft, in which the ratio between the moment of inertia about the spin axis and the lateral moment inertia is greater or less than 1.
