Aircraft, using wall jet to generate a lift, contains a rotor (3) located on the fuselage (2) of the aircraft (1) and circumferential or discontinued ring (4) surrounding the rotor (3), whereas there is an outlet gap (5) between the lower surface of the ring (4) and the opposite surface of the fuselage (2) to direct the air pushed to the outlet gap (5) by a rotor (3). The aircraft (1) contains control means for gradual change of velocity and air flow rates difference between at least two different places on the outlet gap (5) circumference during the flight of an aircraft (1). The control means is for example a ring (4) that is configured so that during the flight of an aircraft (1) the position of at least part of the lower ring surface can be controlled with respect to the opposite ring surface, thus controlling also the geometry of the outlet gap (5). |
