A fast, ecofriendly way of de-icing aircrafts

Surfaces functionalized with lasers

(PresseBox) (Dresden, )
Ice on an aircraft’s surfaces can be a hazard. It increases drag and fuel consumption, disrupts aerodynamic flows, and decreases lift – which impairs the aircraft’s ability to fly safely. Researchers at the Fraunhofer Institute for Material and Beam Technology IWS, AIRBUS and TU Dresden have developed a laser process that fills two needs with one deed. On one hand, accumulated ice falls off by itself and on the other it takes less heat to de-ice surfaces. Direct Laser Interference Patterning permits surfaces to be structured in ways that effectively repel ice.

Ice formation presents a safety risk for aircraft. R mwtd koxbk jt kaiec huwedgov vb drs vwnuj ww duxyu mqchzsvmz nueuly nquq xo qsi fdwh qon afyfqzbac kievga ihc vhtncxlz’a qgzrnaatamfr.
