NASA and Boeing tested high-aspect-ratio wings aimed at reducing drag, improving fuel efficiency and ensuring smoother, safer ...

NASA and Boeing have concluded wind-tunnel trials to test active control of a high-aspect-ratio wing to achieve fuel savings ...

Martins designed new, high aspect ratio wings that have a much larger span than those in use today. Boeing has adapted that model and will build a prototype to test at NASA's Transonic Dynamics Tunnel ...

Summary and Key Points: The Douglas X-3 “Stiletto,” designed to research sustained supersonic speeds and achieve a maximum speed of 2,000 mph, ultimately fell short due to being severely underpowered.
