Modeling the Dynamics of a Catamaran Driven by a Savonius Rotor and a Propeller

The dynamics of a catamaran with a Savonius rotor and a propeller installed on it are considered. Under the action of a stationary wind flow the rotor rotates and drives the propeller, which creates thrust. The angle of the catamaran’s course relative to the wind flow is considered as the control. The control task is to move the center of mass of the hull from the starting point to the given endpoint located strictly upstream of the wind. The possibility of straight-line motion against the wind is shown. The dependence of the average velocity in the stationary mode of movement against the wind on the radii of the Savonius rotor and propeller is analyzed.
