Shape-changing wings are future of aviation: NASA

Wed, Apr 29, 2015, 12:17 PM
Washington, April 29 , 2015: After six months and 22 research flights, NASA has announced the successful completion of initial flight tests of a new morphing wing technology.

The shape-changing wings are not only designed to significantly reduce an aircraft's weight as well as the noise it generates during flight, these flaps could save the industry millions of dollars annually in fuel savings.

In tests, the wing's curve remained set anywhere from -2 to 30 degrees but it can be adjusted as needed even in midflight.

Eventually, flexible wings can make for lighter, more fuel-efficient planes as well as quieter takeoffs and landings, the US space agency said in a statement.

The test team at NASA's Armstrong Flight Research Centre in Edwards, California, flew research flights with the Adaptive Compliant Trailing Edge (ACTE) flight control surfaces that offer significant improvements over conventional flaps used on existing aircraft.

"The completion of this flight test campaign is a big step for NASA's Environmentally Responsible Aviation (ERA) project," said ERA project manager Fay Collier.

"This is the first of eight large-scale integrated technology demonstrations ERA is finishing up this year that are designed to reduce the impact of aviation on the environment," he added.

The technology can be retrofitted to existing airplane wings or integrated into entirely new airframes.
