Airliners have looked largely the same for a long time now. The ongoing hunt for efficiency gains has seen the development of winglets, drag reducing films, and all manner of little aerodynamic tricks ...

As the U.S. prepares to explore the potential efficiency benefits of low drag, high aspect ratio wings with the Boeing/NASA X-66 demonstrator, European researchers are making progress with efforts to ...

How NASA used the F-104 Starfighter's razor-thin wing to explore supersonic handling, shuttle approaches, and X-15 support.

As manufacturers strive to reduce the fuel burn and emissions of their next generation of commercial airliners, longer wings are near the top of the list. Extending the span would reduce cruise drag ...
