Abstract
Long term human space missions require artificial gravity during some phases of the space flight. In this paper we propose a dual spin system to generate artificial gravity based on a classical rotorcraft configuration where the rotating blade-like module provides a 1g-gravity at the tips. The rotating module is eventually stopped by a fluid ring damper. The dynamics and effectiveness of the damper is analyzed; in particular stability is ensured since a Lyapunov function of the system is found. Optimal damper parameters such as fluid viscosity and ring geometry are determined in order to reduce the despinning time.
