Bifilar Pendulum Technique for Determining Mass Properties of Discos Packages

Abstract

A bifilar pendulum was used to determine the mass properties of the Discos (Disturbance compensation systems) packages on the Triad satellite. The pendulum design was unique in that it allowed the package to be rotated into six different angular orientations. Each angular position was located with respect to the center of mass of the package. Analysis and results are given that show that the inertia matrix can be completed using the bifilar pendulum.
