Boeing has unveiled a refined version of its Transonic Truss-Braced Wing (TTBW) ultra-efficient airliner concept. 

The new configuration is designed to offer unprecedented aerodynamic efficiency while flying at Mach 0.80.

From end-to-end, the folding wings measure 170 feet. The high wingspan is made possible by the presence of a truss, which supports the extended length of the ultra-thin wing.

Originally, the TTBW was designed to fly at speeds of Mach 0.70 – 0.75. To increase the aircraft’s cruise speed, the new concept now has an optimized truss and a modified wing sweep. By adjusting the wing sweep angle, the truss can carry lift more efficiently.

The new changes follow extensive wind tunnel testing at NASA Ames Research Center.

The 737-class aircraft concept was developed under Boeing and NASA Subsonic Ultra Green Aircraft Research (SUGAR) program. The research focuses on innovative concepts that reduce noise and emissions while enhancing performancne.
