Airplane Wing Assembles Like a Jigsaw Puzzle and Can Morph Into Any Shape

A new type of airplane wing assembled like a jigsaw puzzle could make for lighter, more efficient aircraft.

NASA and Massachusetts Institute of Technology researchers tested the wing design in a NASA wind tunnel, where the technology performed better than expected, Iphone Cases, one of the wing’s developers and a graduate student at MIT, said in a statement. The new wing is light and flexible, able to adjust its shape midflight depending on the needs of the pilot.

“You can make any geometry you want and LG Cases,” Jenett said. [Supersonic! The 11 Fastest Military Planes]

Conventional airplane wings are made of metal and composite materials, so they’re fairly heave
The lattice-like wing is covered with a thin sheet of polymer and has a density of just 3.8 lbs. per cubic foot (5.6 kilograms per cubic meter).

But lightness isn’t the only advantage of the new wing design. It’s also flexible. By strategically placing stiff and flexible components in the lattice pattern, the researchers can build a wing that changes shape in response to the stresses around it. Instead of having to lift a flap or move an aileron, a pilot could simply maneuver the plane, and the wing would change shape automatically.

“We’re able to gain efficiency by matching the shape to the loads at different angles of attack,” study leader Nicholas Cramer, a research computer scientist at NASA Ames Research Center in Mountain View, California, said in the statement. “We’re able to produce the exact same behavior you would do actively, but we did it passively.”
