Saab has built a wing panel in the composite that is unique in the world and will reduce aircraft CO2 emissions.
Defence group Saab has unveiled a new wing panel in Linköping. The latter is a result of the EU research project Clean Sky, which aims to reduce global aviation’s climate impact.
The panel measuring 9×3 meters in size and will in 2017 test flown at the aircraft manufacturer Airbus aircraft.
On Sunday flown the huge wing portion to Vitoria in Spain where the Spanish company AERNNOVA to build it into an Airbus A340. Because the wing is so large, Saab has hired the giant plane Antonov-12 to cope with the freight.
According to the company’s Business Unit Director Dan Jangblad (Industrial Products and Services), the special design represent a technological breakthrough in the world in terms of to reduce CO2 emissions from aviation in the future. We now need to test flights falling out well.
– What we believe it will lead to considerably less drag, lower fuel consumption and lower emissions, he said.
The company’s engineers made is to build top of an airplane wing without gaps, joints and rivets, which would otherwise increase the resistance of the air flow above the wing.
The rounded front edge of the wing are connected by the wing panel and forming a planar overall.
– The aim is to make the wing so smooth the flow to be laminar, said Dan Jangblad.
The wing panel consists of the bottom of a composite construction with both longitudinal and transverse beams. At that has placed a composite shell that then cured in a mold.
The wing panel must then be mounted on a base. It has so far only made in two copies, one of which was intended for Saab’s own testing.
On Airbusens the other side will come a flow symmetric wing to be mounted.
It comes from the British GKN Aerospace, and is built using simpler technology, according to Jonas Bohlin, technical manager of the project “CleanSky SFWA BLADE” on Saab. One should now make comparisons of the functionality.
Saab’s budget for wing demonstrator in the Clean Sky project amounts to 300 million SEK. The cost is shared by the company and the European Commission.
The company is one of twelve participants and “co-leader” with Airbus.
