Abstract:

An analytical study has been made to determine the effects of mass-loading variations on a hypothetical earth-satellite space station, rotating to provide an artificial gravity. Results indicate that the shifting of masses within the rotating craft could bring about large oscillations in the attitude angles and in some cases the craft could even diverge about an axis other than the axis of initial rotation. Constant-rate inertia wheels and jet-reaction moments can be used to minimize the undesirable motions. Author
