초록

The aircraft has a pair of rotors driven to counter-rotate within a housing. The housing has adjustable air guiding discuss for the rotor stream and a airfoil-like outer shape to generate lift at horizontal flight. The air guiding devices include a circular arrangement of a plurality of individual sectors having tangentially extending blades arranged in a zone below the rotors. In each sector the blades are adjustable in their position relative to the rotor stream. In at least some of the sectors, the blades are arranged in pairs for an adjusting movemen...
