Embodiment Construction

[0036] figure 1 Shown is a part of a flow profile 2 having a flat skin section 4 which is bent to form a circular leading edge region 6 designed as Used to highlight into the flow. The outer side 8 of the skin section 4 comprises a depression 12 terminating in a slit 10, wherein the depth of said depression increases towards the slit 10 from a base area 14 which is in contact with the skin section. The slits 10 on the 4 are spaced apart. For example, the flow pattern body 2 can be arranged on the leading edge of the wing or on the empennage unit such that the outer side 8 of the flow pattern body 2 is exposed to the flow and forms a flow boundary layer on the flow pattern body 2 . The high-energy gas flow can be blown into or drawn out of the boundary layer via the slit 10 , so that the flow around the flow pattern 2 is influenced and in particular the generation of turbulence is delayed.

[0037] The following figures clearly show that the flow pattern body 2 is produced b...

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.

Description

[0001] Cross References to Related Applications [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...
