DLR has been conducting research into swept-forward wings at its Braunschweig facility as part of the EU New Aircraft Concepts REsearch (NACRE) project. Aerodynamic drag is to be reduced using what is known as 'laminar-flow technology'. For long-distance aircraft in particular, the swept-forward wing combined with laminar-flow technology produces a clear fuel saving. This computer-generated image shows the swept-forward wing concept.
