Study on passive nutation dampers. Volume 2: Damper selection and dimensioning

Passive type nutation dampers were analyzed for single spin satellites. Types studied are: pendulum with eddy current damping, tube with endpots damper, and partly filled annular damper. A mass-spring-dashpot damper was also considered. A selection and dimensioning procedure of damper type is presented. The type of damper which should preferably be used in a given mission depends on both mission requirements and satellite parameters. A rigorous and a simplified dimensioning procedure is given for the pendulum and tube with endpots damper. The selection and dimensioning procedure is exemplified for three satellite missions defined by ESTEC. For volumes 1 and 3, see ESR-96980 and ESR-96982.
