Each rotor wing has a plurality of blades extending outward from a central hub to blade tips. The blade tips of the rotor wings circumscribe respective circles centered on the corresponding central hubs during rotation of the rotor wings and each fixed wing set is located generally below the circumscribed circle of only one of the rotor wings.
