797

Look at this new aircraft....
Boeing is preparing a 1000 passenger jet that could reshape the Air travel industry
for the next 100 years. The radical Blended Wing design has been developed by
Boeing in cooperation with the NASA Langley Research Center . The mammoth plane
will have a wing span of 265 feet compared to the 747's 211 feet, and is designed to
fit within the newly created terminals used for the 555 seat Airbus A380, which is 262
feet wide.
The new 797 is in direct response to the Airbus A380 which has racked up 159 orders,
but has not yet flown any passengers. Boeing decide to kill its 747X stretched super jumbo
in 2003 after little interest was shown by airline companies, but has continued to develop
the ultimate Airbus crusher 797 for years at its Phantom Works research facility in Long
Beach, Calif.
The Airbus A380 has been in the works since 1999 and has accumulated $13 billion in
development costs, which gives Boeing a huge advantage now that Airbus has committed
to the older style tubular aircraft for decades to come.
There are several big advantages to the blended wing design, the most important being
the lift to drag ratio which is expected to increase by an amazing 50%, with overall weight
reduced by 25%, making it an estimated 33% more efficient than the A380, and making
Airbus's $13 billion dollar investment look pretty shaky.

High body rigidity is another key factor in blended wing aircraft, It reduces turbulence and creates less stress on the air frame which
adds to efficiency, giving the 797 a tremendous 8800 nautical mile range with its 1000 passengers flying comfortably at mach 0.88 or
654 mph (+-1046km/h) cruising speed a nother advantage over the Airbus tube-and-wing designed A380's 570 mph (912 km/h).
The exact date for introduction is unclear, yet the battle lines are clearly drawn in the
high-stakes war for civilian air supremacy.

Looks nice. Why haven't they used the blended wing design in the past if it's so much more efficent? There must be some drawbacks to this design. Good luck getting a window seat for one.

The germans had plans for something similar 65 years ago:

Yeah, there's been a few. Here's one from Northrop:

Why didn't they catch on? Is the design unstable about the vertical axis?

Always thought Dutch roll would be a problem....but the 'Naughty French Stewies' would make it all worthwhile!~

Besides looking very different from the current crop of airliners (some people don't like change...), can you imagine sitting in one of the outer seats? How far up or down do you think you'd be moving when the plane banks?

Stability was the reason the earlier flying wing aircraft didn't catch on. This has been solved since though as the B-2 proves.

One of the reasons they haven't used the blended wing is that passengers want to be able to see out a window...as per human nature we want to see what's going on so sitting in the middle of an airplane 50 feet from the nearest window might not go over well with the PAX. There is an article in Popular Science about flight this month...good read.

Perhaps a nice camera view from the IFE tv of a couple of different views outside the aircraft.

De-icing would be a bugger. The entire upper surface would have to be done, since any contaminate could blow right into the above the wing engines.

Raises lots of interesting questions....

I was gonna say that picture's from a 10 year old Popular Mechanics issue, but apparently it's actually 12 years old.

might be similar to a dc9 variation. But with the dc9(mdcrap) you get the up and down feeling quite a bit. Especially near the front away from the wing.

It's probably going to end up being a bomber for USAF first.
