Another area to improve aircraft is to increase their aerodynamic efficiency. The Boeing 777X's extended wingspan allows the aircraft to increase the wing aspect ratio and reduce lift-induced drag ...

When a hawk folds its wings, it plummets to the earth in a controlled high-speed dive. Not exactly the kind of scenario we’d imagine being ideal for modern aircraft. But wing folding can have ...

The 777X, with its new wing design and folding wing system, should allow the aircraft to arrive at smaller gates, potentially at your favorite airport.

The fixed-wing plane may be a thing of the past if NASA's latest venture is successful. The space agency as part of the "Spanwise Adaptive Wing" (SAW) project recently began testing planes with ...

NASA's rendering of an aircraft with the Spanwise Adaptive Wing. NASA Articulating airfoils, or folding wings, are nothing new to aviation. They’ve been used for decades as an efficiency tool to ...

However, the size of a plane's wings is limited by the size of airport gates. Yet if the wingtips can fold, planes can still have longer wings in flight and fit into airport gates on the ground.

Technology Aviation Boeing’s new 777x planes have wings so wide they need to fold just to fit at the gate Aviation can be such a drag. Rob Verger May 23, 2018 1:16 AM EDT ...

It has hinged wingtips measuring 12 feet, with locking pins to prevent them from folding during flight, and the longest aircraft body and widest wingspan ever produced by Boeing, at 252 feet and ...

NASA conducts a flight test series to investigate the ability of an innovative technology to fold the outer portions of wings in flight as part of SAW project. Flight tests took place at NASA’s ...
