Boeing's unveils radical 'transonic' wing design
CNN (Travel) ^ | 1/11/19 | Jack Guy

Posted on 01/12/2019 11:59:41 AM PST by ProtectOurFreedom

Boeing's latest innovation is an extremely thin, folding wing that will offer unprecedented aerodynamic efficiency, according to a news release from the company.

The Transonic Truss-Braced Wing...extended wingspan of 170 feet...increased top speed from a planned Mach 0.70-0.75 to Mach 0.80 by modifying the wing sweep and optimizing the supporting structure, changes which allow the truss to carry lift more efficiently.

Boeing has developed the wing in partnership with NASA over the course of nearly a decade.

Their work is part of the Subsonic Ultra Green Aircraft Research program, which encourages the development of less noisy, more efficient aircraft that also improve on performance.

The BBJ 777X planes will have a range of 11,645 nautical miles, enabling them to offer the longest commercial flight in the world. Depending on which routes the jets are used on, the new models mean Boeing could wrestle the crown for farthest nonstop travel away from Airbus.

...the Boeing 777X hit a production milestone late last year when its major fuselage sections -- the airplane's nose, mid and aft sections -- were brought together. Engines have also now been added.

...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.

Everything old is new again. From about 1930 or so.

Only available seats for late bookers would be the middle seats.

Haven’t I seen that machine holding the plane in the second photo in some porn videos?

I look forward to those 16-18 hours non-stop flights. NOT!!!

...The goal is to establish the flutter boundaries for the flexible wing and show that active control can suppress flutter and provide gust-load alleviation, allowing the weight penalty for a slender wing to be minimized and the drag reduction realized...

In other words, when Achmed and Mubdallah manage to introduce a virus into the active control computer the whole airplane will shake itself to pieces and crash.

That is way to innovative. I’m going to need to see a few 100,000 flight hours before I would step foot.

“...it has locking pins to prevent them from folding during flight...” — Ask Richard Branson about that (hint - feathering system).”

Branson’s was a system designed to fold during flight that malfunctioned. The US Navy has been using folding wings with locking pins successfully for decades.

The average passenger’s max flight endurance is maybe half of that.

...

I thought that was pilot error with other contributing factors.

My guess is Boeing just wants the free publicity, but will never build it.

They’ve had other radical designs that were never built.

Naw, that’s just a strut. And aerodynamic strut to be sure, but just a strut.

That would be some pretty narrow landing gear.

Naw. It's not that bad. Ive done a handful of ULH flights (>7000 miles). Its fatigueing but doable.

That’s the first (well, not the first, but maybe the third) thing that came to my mind. It’s a biplane.

“Boeing’s unveils radical ‘transonic’ wing design”

Everything is “trans” these days.

And why is it called “trans” if it only goes 0.8 Mach?
