Abstract:

For the layout of a nutation damper for the EQUATOR-S satellite, a nutation damper with two identically symmetrical liquid dampers was observed. The damper consists of two pipes with a circular diameter. At the satellites given moments of inertia, as well as at its spin frequency, certain restrictions with regard to the dampers geometry were calculated so that a good nutation damping with booms swinging both inward and outward was ensured. The dampers were constructed along these parameters and tested in an air-set pendulum. The theoretical damping on the pendulum was measured and compared with the experiment, with the results concurring to a great degree.
