Detailed explanation-1: -NASA has successfully applied a new technology in flight that allows aircraft to fold their wings to different angles while in the air. The recent flight series, which took place at NASA’s Armstrong Flight Research Center in California, was part of the Spanwise Adaptive Wing project, or SAW.

Detailed explanation-2: -All aircraft wings take forces that would cause bending; this is the physics of flight as the wings support the fuselage’s weight. But with the 787, the wing structure bends more under this force.

Detailed explanation-3: -An elliptical planform is the most efficient aerodynamic shape for an untwisted wing, leading to the lowest amount of induced drag.
