The results of dynamic behavior research of compound spacecraft with frameless rotating solar sail and powered gyro with Hook gimbal suspension are presented. Solar sail with central rigid insertion is used for transmission of angular momentum as well as momentum to space platform. Stability of stationary shape of a sail at regular precession is proven by direct Lyapunov method. Using modal decomposition, adaptive observer algorithm is developed for estimation of oscillation rates of membrane disk for their active damping.
