Summary:

- NASA's Armstrong Flight Research Center is testing a new wing concept called the Adaptive Compliant Trailing Edge (ACTE) that can change the shape of its wings during flight to improve efficiency and performance.
- The ACTE wings are made of flexible composite materials that can morph and adapt to different flight conditions, reducing drag and fuel consumption compared to traditional rigid wings.
- This technology could lead to more efficient and environmentally-friendly aircraft designs in the future, as the ACTE wings can adapt to different phases of flight, from takeoff and landing to cruising.
