The outer skin (100) of an aerodynamic body ( 40) has perforations (200) arranged in particular patterns in respective spanwise extending groups or bundles (250). Each perforation is preferably a micro-slot with a length of 100 to 3000 μm and a width of 50 to 250 μm. Air is sucked through the micro-slots from the boundary layer flowing over the outer skin, to achieve boundary layer control. In each bundle, the pattern, size, orientation, and other parameters of the micro-slots are designed to achieve mutual destructive interference of flow dist...
The invention claimed is: 1. A laminar flow control apparatus comprising: an outer skin having a plurality of perforations communicating therethrough, and having an outer surface adapted to be exposed to an airflow including a boundary layer airstream flowing along said outer surface; and a suction system communicating with said perforations on a side of said outer skin opposite said outer surface and adapted to suck air from the boundary layer airstream through said perforations; wherein flow disturbances are created in the boundary layer airstream due...
