Boeing, in collaboration with NASA, has developed a new wing concept that is said to be more aerodynamic and fuel efficient.
The Transonic Truss-Braced Wing (TTBW) concept is a part of the company’s Subsonic Ultra Green Aircraft Research (SUGAR) program.
According to Boeing’s engineers, the new wing concept has been designed to fly higher and faster than the previous TTBW concepts.
Moreover, the new configuration offers an aircraft unprecedented aerodynamic efficiency while flying at Mach 0.80 speeds.
The folding wings measure 170 feet from an end-to-end basis. This high wingspan is made possible by the presence of a truss, which supports the extended length of the ultra-thin wing.
The TTBW concepts were originally designed to fly at speeds of Mach 0.70 – 0.75. But in order increase the aircraft’s cruise speed, the latest TTBW concept has utilized an optimized truss and a modified wing sweep.
According to Boeing, the truss can carry lift more efficiently by adjusting the wing sweep angle.
The end result is a more integrated design that significantly improves vehicle performance.
The new changes follow extensive wind tunnel testing at NASA Ames Research Center.
For nearly a decade, Boeing and NASA have been studying the concept as part of the SUGAR program.
The research focuses on innovative concepts that reduce noise and emissions while enhancing performance.
