Abstract
Since airships are an environmentally-friendly, safe and energy-saving vehicle, they are the most suitable vehicles to meet the modern social needs. If small airships with highly enhanced maneuverability can be realized, they will satisfy people's desire to fly freely in the air without anxiety. However, conventional propulsive systems have little possibilities to improve maneuverability. Hence, we try to adopt cycloidal propellers on airship as a new propulsive system. Cycloidal propeller is a type of propulsion system to generate thrust by controlling attack angles of blades rotating constantly. By adjusting the vehicle's gravity center and the buoyancy center as close as possible, we can perform somersault around the center of gravity of the airship.
