In the lifting surface (11), the rotor (22) of the lifting surfaces/rotor assembly (1) has an inlet opening (21) that can be closed by a closing means (3) and an outlet opening (25) that can be closed by a closing means (3). The closing means (3) are partially air-permeable in the closed state. When the rotor is running (22) and the closing means (3) are closed, this air-permeability allows for a targeted influencing of the aerodynamic properties of the lifting surface (11). In this way, a suctioning away of the air on the upper side of the lifting surface can be achieved by an underpressure in the region of the inlet opening (21) of the rotor (22) in the lifting surface (11), and simultaneously, a blowing out of air on the underside of the lifting surface can be achieved by an overpressure in the region of the outlet opening (25). Advantageously, in this way, the decelerated boundary layer on the surface of the aerofoil is reduced in thickness (δG) in the region of the inlet opening (21) via suctioning, and a high-energy outer layer can be applied to the profile of the lifting surface (11). More advantageously, the air resistance of the lifting surface (11) can thereby be reduced and the uplift thereof increased, which leads to improved flight characteristics and higher energy efficiency of an aircraft with a lifting surfaces/rotor assembly (1). Particularly advantageously, the suctioning occurs in the region of the closing means (3) of the inlet opening (21) of the rotor (22), whereby otherwise, due to unevenness caused by the closing means (3), there is a thicker boundary layer (δG) on the surface.
