ABSTRACT:
A nutation damper apparatus capable of damping small nutation angles in a satellite. A permanent magnet mounted on the free end of a pendulum arm oscillates back and forth parallel to an adjacent conductive plate in the form of a circular segment having a cross-sectional area that increases from the center to its lateral ends, and induces in the plate a magnetic flux which is proportional to the deviation angle of the pendulum from its rest position.
