Boeing to take on Airbus with (1000 seat) giant 797 Blended Wing plane
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 Centre.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 .88 or 654 mph (+-1046km/h) cruising speed another 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.

So, Nortrop has us talking about a super-sized B-2? Interesting isn't it, how it almost looks like--but not performs like--the mysterious, so-called black triangles.
Can any reasonably minded engineer accept that they can simply enlarge the B-2 plans tp make a larger version? That is not a plane in the sky, it is a pie in the sky!

I would ask is would you be flying a large transport in skies where stealth is needed to avoid interception? If so, what for?

If it is built for commercial purposes then cost will drive it - so any fancy materials will almost certainly be ditched in favour of "standard" commercial materials - and although carbon fibre may be "stealthy" that is incidental.
