Video: Hybrid Laminar Flow Technology (HLFC)
Hybrid Laminar Flow Technology (HLFC), a combination of active flow control and specific laminar profiles, is a promising possibility to reduce the drag of aircraft wings and empennage. While the basic idea has been known for a very long time and has already been experimentally investigated and validated, this technology has hardly been able to establish itself in series applications. The main reasons for this are, besides the high system complexity, especially the very high manufacturing costs and the unclear behaviour of the suction noses during continuous use. This is precisely where the DLR developed Tailored Skin Single Duct (TSSD) design comes into play: significantly reducing manufacturing costs, especially for the microperforated outer skin, and opening up new possibilities for cleaning and maintenance thanks to its complete dismantlability.
