Abstract

A flow body and method for taking in and/or blowing out fluid through a plurality of openings in a flow surface section of a flow body is disclosed. In some aspects, the flow body includes a flow surface section that extends in a flow body wingspan direction and a flow body chord direction and with a plurality of fluid lines that lead into the flow surface section and respectively form an opening therein. In some aspects, the method includes taking in and/or blowing out fluid through at least one fluid line that leads into a flow surface section of a flow body and respectively forms an opening therein.

First claim

The invention claimed is:

1. A method for taking in and blowing out fluid through a plurality of fluid lines that lead into a flow surface section of a flow body and respectively form an opening therein, wherein the flow body extends in a flow body span direction, a flow body chord direction, and a flow body thickness direction, wherein, relative to the flow body thickness direction, the flow body chord direction is substantially parallel to a direction of a flow of ambient air along the flow surface and the flow body span direction is substantially orthogonal to the direction of the flow of ambient air along the flow surface, wherein a plurality of openings forms at least one row of first openings and second openings that are arranged in a successive manner viewed in the flow body span direction, and wherein the first and the second openings are alternately arranged in a successive manner in the flow body span direction, the method comprising:
taking in fluid through the first openings during a first time segment and simultaneously blowing out fluid through the second openings during at least a fraction of the first time segment; and
blowing out fluid through the first openings during a second time segment and simultaneously taking in the fluid through the second openings during at least a fraction of the second time segment.

2. The method according to claim 1 , wherein the first time segment and the second time segment are identical and recur alternately.

3. The method according to claim 1 , wherein an end section of at least one fluid line of the plurality of fluid lines is shaped in a plane defined by the flow body chord direction and the flow body span direction such that the end section of the at least one fluid line is tapered or widened in a flow body thickness direction.
