DLR has built a large air­craft com­po­nent out of CFRP as part of the EU Smart In­tel­li­gent Air­frame Struc­tures (SARIS­TU) project. Struc­tural Health Mon­i­tor­ing (SHM) with Lamb waves is a promis­ing tech­nique for con­tin­u­ous­ly test­ing fi­bre com­pos­ite struc­tures for dam­age dur­ing op­er­a­tion.

Fund­ed with­in the frame­work of the Ger­man Avi­a­tion Re­search Pro­gramme (Lu­Fo), the ProfiRumpf project by the Ger­man Fed­er­al Min­istry for Eco­nom­ic Af­fairs and En­er­gy (BMWi) has, for the first time, suc­ceed­ed in the pro­duc­tion of dou­ble-curved fuse­lage seg­ments from alu­mini­um fi­bre­glass lam­i­nate in as­sured qual­i­ty us­ing co­or­di­nat­ed robot tech­nol­o­gy.

Dur­ing the win­ter, air­craft suf­fer in the bit­ing cold. As is the case with cars, ice can form on air­craft flight deck win­dows and flight in­stru­ment sen­sors. The wings are al­so among the crit­i­cal points of air­craft, and ic­ing can lead to sig­nif­i­cant aero­dy­nam­ic penal­ties. The Ger­man Aerospace Cen­ter (Deutsches Zen­trum für Luft- und Raum­fahrt; DLR) has found a so­lu­tion to this is­sue. A new elec­tric de-ic­ing tech­nol­o­gy us­ing car­bon fi­bres melts the ice ef­fi­cient­ly and can even pre­vent its for­ma­tion. The func­tion­al­i­ty and en­er­gy ef­fi­cien­cy of the in­no­va­tive heat­ing sys­tem were in­ves­ti­gat­ed us­ing the de-ic­ing test bed at the Tech­nis­chen Uni­ver­sität Braun­schweig (TU BS).

The DLR Institute of Lightweight Systems has the know-how for the design and realisation of adaptable, efficient composite structures and lightweight systems. The institute forms the bridge between basic research and industrial application. With its expertise in multifunctional materials, structural mechanics, functional lightweight construction, fibre composite technology, adaptronics and composite process technology, the institute is oriented along the entire supply chain for the manufacture of flexible, efficiently manufactured and tolerant lightweight structures. With its wide range of services and visionary scientists, the Institute is a trusted partner of industry, academic institutions, the German Research Foundation (Deutsche Forschungsgemeinschaft; DFG), research institutions, ministries and regulatory authorities.
