Abstract:
This study presents an additional analytical approach to the dynamics of a spinning structure which is proposed to be a conceptual design of a solar sail traveling in space. A rigid hub and an elastic plate are considered and employed to construct a discrete-continuous framework. A hybrid coordinate dynamical system is introduced and used for deriving the governing equations and the
