The subject of the invention is an enhanced driver unit for circular wing, which can be used for driving structure based on aerodynamic lifting effect having a circular wing embodiment ensuring a better efficiency and a more balanced drive, and also which improves the stability and controlling ability of lifting structures established with circular wing. In the driver unit according the invention a circular wing is created with aerodynamically suitable profile for ensuring the lift, with an impeller installed near to it, which rotates at its middle around a drive shaft, which impeller blows the air from central direction laterally towards the circular wing, on which a lifting force is produced thanks to the profile of the airfoil. It is characterized by that in the driver unit (3) according to the invention a fan (7) is used above the impeller (5) in order to enhance the air blowing effect of the impeller (5), which blows the air onto the blades of the impeller (5) from above. The invention is furthermore such a driver unit in which a circular wing is installed for providing lift by means of aerodynamically suitable profile, and an air blowing device is installed at its central location for blowing the air from a central direction laterally to the circular wing, where the shape of the wing profile ensures a lift. It is characterised by that, in the upper part of the driver unit (3) according to the invention there is a vertically aligned jet (13) at the central location of the circular wing, and a deflector (14) is placed in the given case on a closing plate (6) below the jet (13), which deflects the air flow discharged vertically downwards to the direction of the circular wing (2) laterally, thus the intake air (AIN) of the jet (13) is discharged from the driver unit (3) in lateral direction as the air to circular wing (ACW), and its direction could be influenced by means of suitably adjustable nozzle opening (9).
