    Air traffic increases in volume by up to six percent every year. To make air travel more environment-friendly and quieter, researchers at the German Aerospace Center (Deutsches Zentrum für Luft- und Raumfahrt; DLR), together with partners Airbus, EADS Innovation Works and Cassidian Air Systems, have been carrying out research to reduce the aerodynamic drag of aircraft and have developed an alternative to the traditional leading-edge slat. A morphing leading edge is expected to replace slats to create an innovative high-lift system. This construction significantly reduces air resistance and noise during landing.

Technologies for future aircraft generations require significant reductions in flow resistance, fuel emissions, and airframe noise. Innovative morphing structures are the key technology for attaining this objective in the near future. The droop nose developed by the DLR Institute of Composite Structures and Adaptive Systems is a gapless and flexible wings leading edge that is being analysed in wind tunnel tests. It amalgamates contradictory requirements such as flexibility (in the vertical direction) and stiffness along the wing span.
