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 ...

Last blog, John Elwell, a friend of Bob Simmons during the last five or six years of his life, shared stories from this great innovator. Here is Elwell's discussion on the planing hull: Aspect ratio ...

Making the wings on passenger jets thinner and longer can go a long way toward reducing drag and making them more efficient, but they vibrate like crazy. Engineers at NASA and Boeing are now tackling ...

Can Northrop build an oblique flying wing X-plane and revolutionise the design of long-range strike aircraft? DARPA has given it a chance to find out An aircraft that can loiter like a Global Hawk, ...

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 ...
