The Big Wing

Via NASA Newsletter

"NASA and Boeing have finished wind‑tunnel testing on an advanced aircraft concept known as the truss‑braced wing. This design uses an ultra‑long, slender wing supported by aerodynamic trusses, a configuration that could significantly cut fuel use and lower operating costs for future commercial aircraft.

Originating from NASA‑supported aeronautics research, the transonic truss‑braced wing has progressed from an early idea to a viable design through step‑by‑step collaboration."
