In a wing (11), a rotor (22) of a wing-rotor arrangement (1) has an inlet opening (21) which can be closed by a closure (3) and an outlet opening (25) which can be closed by the closure (3). In this case, the closure (3) is partially breathable in the closed state. When the rotor (22) is operated and the closure (3) is closed, this air permeability can pertinently influence the aerodynamic properties of the wing (11). As a result, air on the top side of the wing can be sucked by means of a negative pressure in the region of the inlet opening (21) of the rotor (22) in the wing (11), and air on the bottom side of the wing can be blown out by means of an overpressure in the region of the outlet opening (25). Advantageously, the thickness ([delta] G) of a decelerated boundary layer on the top side of the wing can be reduced by suction in the region of the inlet opening (21), and a higher-energy outer layer can be applied to the profile of the wing (11). More advantageously, the air resistance of the wing (11) can be reduced and the lift thereof can be increased, which results in better flight characteristics and higher energy efficiency of an aircraft having a rotor-wing arrangement (1) according to the invention. Suction is particularly advantageously achieved in the region of the closure (3) of the inlet opening (21) of the rotor (22), in which region a thicker boundary layer ([delta] G) would otherwise be formed due to unevenness on the surface caused by the closure (3).
在机翼(11)中机翼‑转子装置(1)的转子(22)具有可被封闭件(3)封闭的进入口(21)和可被封闭件(3)封闭的排出口(25)。在此,封闭件(3)在关闭状态下是部分透气的。在转子(22)运转且封闭件(3)关闭的情况下,这一透气性能够有针对性地影响机翼(11)的空气动力学性质。由此,通过在机翼(11)内转子(22)的进入口(21)的区域中的负压,能够实现对机翼的顶侧上的空气的抽吸,并且同时通过在排出口(25)的区域中的过压能够实现对机翼的底侧上的空气的吹出。有利地,由此在机翼顶侧上的减速的边界层可以在进入口(21)的区域中通过抽吸减少其厚度(δG),并且可以将更高能的外层应用在机翼(11)的形廓上。更有利地,可以降低机翼(11)的空气阻力并且提高其升力,这实现了具有根据本发明的转子‑机翼装置(1)的飞行器的更好的飞行特性和更高的能效。特别有利地实现在转子(22)的进入口(21)的封闭件(3)的区域中的抽吸,否则在所述区域中会因为由封闭件(3)导致的表面上的不平整而形成更厚的边界层(δG)。
