FIELD: aeronautical engineering; development of rotary-wing flying vehicles. SUBSTANCE: aircraft wing is made in form of thin-walled axis-symmetrical revolving disk whose cavity is divided into two parts by means of diametral partition. One part is used for extensible blades and other part is used for stowage of compressed air escaping from nozzles mounted over periphery tangentially relative to wing circle which create torque. Extensible blades are connected by means of ropes with drum mounted in central portion of wing. Blades are extended and retracted under various conditions of flight due to rotation of drum and section of centrifugal forces during rotation of wing. EFFECT: enhanced efficiency. 3 cl, 1 dwg
