Credits: NASA/Carla Escamilla NASA researchers recently put a new wing design, appearing long and thin with a lightweight structural design, through a series of grueling tests to find its structural limits.
What they found left them encouraged about the wing’s potential, even when they pushed it past its intended limits. The 15-foot Structural Wing Experiment Evaluating Truss-bracing (SWEET-15) test article is part of NASA’s research to develop future ultra-efficient aircraft. The design incorporates a long wing supported by an aerodynamic strut, based on NASA’s earlier Transonic Truss‑Braced Wing concept.
The research team is working to understand whether SWEET-15’s design and its new lightweight structural designs could help commercial airliners save fuel. But first, they need to understand how it behaves under the kinds of force wings experience in flight. Lab technicians Phil Tofts, Chris McLain, and Jeff Howell and NASA engineers Erin Anderson and Richard Larson prepare the 15-foot Structural Wing Experiment Evaluating Truss-bracing model in the Flight Loads Laboratory at NASA’s Armstrong Flight Research Center in Edwards, California, on Thursday, Dec.
11, 2025. The model is part of NASA’s research to develop technologies for future ultra-efficient aircraft. NASA/Christopher LC Clark The SWEET-15 design originated with combining five different advanced composite manufacturing and assembly technologies that enabled the novel structural design.
The 15-foot-long test article was then designed and fabricated at NASA’s Langley Research Center in Hampton, Virginia, before traveling to NASA
