Nasa is testing a new type of plane with flexible wings
The space agency says its design could make long range flights more fuel efficient.

Nasa is planning a new round of tests for its flexible wings technology that the space agency believes could feature on aircraft of the future.
The X-56A uses highly flexible, lightweight wings rather than rigid ones in an attempt to create more fuel efficient long-range aircraft.
A new set of flights to test the technology will take place in November, Nasa said, and will focus on overcoming “past challenges” from earlier tests.

Project manager Cheng Moua said: “We want to show that this kind of wing can be built and the control technology exists to suppress flutter on them.”

Once overcome however, the agency predicts major steps forward for long-range flight.
Those tests will take place using a small, remotely piloted aircraft built by US technology manufacturer Lockheed Martin, at Armstrong Flight Research Base in California.
