Abstract

A flow profile (2) for a vehicle, the flow profile (2) comprising at least one planar skin section (4) and at least one active flow control device (18), wherein the at least one The flat skin section (4) has an outer side (8), an inner side (16) and at least one opening (10) penetrating the skin section, the at least one active flow control device (18) being designed Into used to control the air volume. The at least one active flow control device (18) comprises an air discharge section (21) fluidly connected to the at least one opening (10), wherein the air discharge section (21) and the at least one planar The skin section (4) is produced by means of a layer manufacturing process in the form of a one-piece part without joints, and the air outlet section at least partially supports the skin section (4) in a load-bearing manner.

[0002] This application claims priority from German Patent Application No. 102015110782.1 filed on 03.07.2015. technical field

[0003] The invention relates to a flow profile with an active flow control device, a vehicle equipped with the flow profile, and a method for producing such a flow profile in the form of a one-piece component. Background technique

[0004] Various active flow control devices known in the art are coupled to components exposed to the flow and include perforations, slits or other openings through which air can be blown into formed in the In or extracted from the flow boundary layer on the component. In this way, the flow around the component can be actively influenced such that, for example, a stall can be delayed and / or the flow around the component can become largely laminar.

[0005] The means for delivering air are usually arranged inside the component and are fluidly connected to the one or more...
