Boeing unveils "green" wing design

A faster Mach 0.80 speed is made possible by a modified wing sweep and truss optimization.

Boeing has shown for the first time a new transonic truss-braced wing (TTBW) airliner concept which it says would fly higher and faster than previous ultra-efficient airliner concepts. The high wingspan is made possible by the presence of a truss, which supports the extended length of the ultra-thin wing. When the plane is flying at Mach 0.80, the new type of wing would provide an unprecedented degree of aerodynamic efficiency, the company said in an announcement today.

The 737-class aircraft concept was developed under Boeing and NASA Subsonic Ultra Green Aircraft Research (SUGAR) program.

Slated to be one of the next darlings of commercial aviation, the Boeing 777X hit a production milestone late a year ago when its major fuselage sections - the airplane's nose, mid and aft sections - were brought together.

In December, the aerospace company announced its next generation of business jet, allowing for non-stop flight between "any two cities on Earth".

The 777X is in excellent position to claim the crown of longest uninterrupted flight from Airbus, whose A350 XWB recently claimed the title of longest range jetliner.

It has hinged wingtips measuring 12 feet, with locking pins to prevent them from folding during flight, and the longest aircraft body and widest wingspan ever produced by Boeing, at 252 feet and 235 feet, 5 inches, respectively.

With several production milestones reached in late 2018, the 777X is the future of commercial aviation which is likely to arrive sooner rather than later.
