Abstract
We describe the aerodynamic design of an HLFC system for the wing of a large transport aircraft and compare it to the the HLFC system installed in the VTP of the DLR A320 ATRA aircraft. For the VTP we used the ALTTA-design with a laser-drilled microperforated titanium sheet with only one microperforation and small suction chambers beneath it. For the wing we designed a system with only one large plenum and controlled the suction with the help of variable microperforation. Some specific challenges of an HLFC design on a wing in contrast to a VTP application are highlighted here.
