Aircraft and method for operating an aircraft

An aircraft, comprising a wing which, viewed in section, is delimited on one side by a lower first profiled surface, that is on the side of the aircraft facing the ground when the aircraft is operated as intended, and on the other side is delimited by an upper second profiled surface, which merges at an aerofoil transition point with the first profiled surface, wherein the first profiled surface encloses at least one air inlet opening and the second profiled surface has at least one air outlet opening and the aircraft has a drive apparatus with an air delivery apparatus which is provided and designed for sucking air through the at least one air inlet opening and for discharging the sucked air through the at least one air outlet opening, wherein the at least one air outlet opening is overlapped at least in part by a deflecting element which, together with the second profiled surface delimits an air outlet gap which is flow-connected to the air outlet opening, wherein conveying the air through the at least one air inlet opening by the drive apparatus occurs from the underside of the aircraft, and wherein during flight operation of the aircraft the drive apparatus is operated in such a way, that air in the form of an air intake stream is conveyed from the underside of the aircraft in the direction of its upper side and an air film that runs along the second profiled surface detaches from the wing at a tear-off point and flows as a free jet air stream onto the underside of the aircraft, such that a toroidal support vortex is stimulated in the manner of a potential vortex which is located at least in part between the first profile surface and the ground and to which both the free jet air flow and the intake air flow are tangential.
