Disclosed is a airfoil (7) for flow control, comprising an outer skin (13) in contact with an ambient air flow (21), wherein the outer skin (13) extends between a leading edge (23) and a trailing edge(25) with two opposite lateral sides (27a, 27b), and surrounds an interior space (29), and wherein the outer skin (13) comprises a porous section (31) in the area of the leading edge (23), a pressurechamber (15) arranged in the interior space (29) and fluidly connected to the porous section (31), an air inlet (17) fluidly connected to the pressure chamber (15), and an air outlet (19) fluidly connected to the pressure chamber (15). The object, to provide a simple and compact airfoil with reduced drag an increased efficiency, is achieved in that the air inlet (17) and the air outlet (19) are integrated in a common inlet/outlet device (20) that is arranged in one lateral side (27a) of the outer skin (13) and that is configured to selectively let air in from the ambient air flow (21) or discharge air into the ambient air flow (21), and in that the air inlet (17) is formed as an opening (35) that is flush with the outer skin (13).

    公开的是一种用于流动控制的翼型件(7),该翼型件(7)包括:外蒙皮(13),外蒙皮(13)与环境空气流(21)接触,其中,外蒙皮(13)在前缘(23)与后缘(25)之间延伸,外蒙皮(13)具有两个相反的横向侧部(27a、27b),并且外蒙皮(13)围绕内部空间(29),并且其中,外蒙皮(13)在前缘(23)的区域中包括多孔部分(31);压力室(15),压力室(15)设置在内部空间(29)中并且以流体的方式连接至多孔部分(31);空气入口(17),空气入口(17)以流体的方式连接至压力室(15);以及空气出口(19),空气出口(19)以流体的方式连接至压力室(15)。用以提供具有减小的阻力和增加的效率的简单且紧凑的翼型件的目的通过以下方式来实现:将空气入口(17)和空气出口(19)在共用的入口/出口装置(20)中结合成一体并且空气入口(17)形成为与外蒙皮(13)齐平的开口(35),入口/出口装置(20)设置在外蒙皮(13)的一个横向侧部(27a)中,并且入口/出口装置(20)构造成选择性地使空气从环境空气流21进入或者将空气排放到环境空气流(21)中。
