Up to now, aircraft have been put together in huge assembly cells, but to build the necessary facilities is expensive and time-consuming. That is why Fraunhofer researchers have come up with a fl exible assembly-line concept that features robots working in the same way they do in automotive production. The developers are presenting their new manufacturing approach at the Composites Europe trade fair in Stuttgart in Hall 4, Booth D03. One of this future assembly line’s fi rst elements can also be seen there: a versatile component gripper made of lightweight CFRP (carbon fi ber reinforced plastic).
The Fraunhofer Institute for Building Physics IBP and the Fraunhofer Institute for Manufacturing Technology and Advanced Materials IFAM are presenting their in-novations as part of the “Clean Sky” Joint Technology Initiative (JTI) at Aerodays 2011 in Madrid, Spain.
Fuel savings – "Sharkskin" riblet structures measurably reduce flow resistance Practical trials carried out by the Fraunhofer IFAM as part of the HAI-TECH project (English: SHARK-TECH) confirm the effectiveness of riblet structures.
