The invention relates to an aerodynamic body with a plurality of nozzles forthrottling a fluid flow to be removed by suction through the nozzles (1) in aself- regulated fashion. The invention also pertains to an aircraft that isequipped with a suction system of this type. Lastly, the invention pertains tothe utilization of a plurality of the aforementioned throttling nozzles (1) inorder to reduce the frictional losses on a surface (8), around which a fluidflows. The aerodynamic body according to the invention comprises a pluralityof throttling nozzles (1) with a throttle section (5) that is defined by aninlet (2) and an outlet (3), wherein the interior wall of this throttlesection is realized in such a way that the effective flow cross section Aw isreduced in a self-regulated fashion due to the creation of turbulences on theinterior wall of the throttle section (5) as the pressure differential betweenthe inlet (2) and the outlet (3) of the throttle section (5) increases.
