Look at this new aircraft...guess we are not going to be outdone by the French A380. 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 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 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.

Status: offline 		Guys....before you drool all over yourselves....the blended wing body concept has been studied for many, many years by Boeing in St. Louis. It started before the merger, when they were still McDonnell-Douglas. The most likely scenario for bringing a BWB concept to completion will be a military multi-mission cargo plane, like the C-135, in which the government bears most of the risk of development. Right now Boeing Commercial Airplanes is doing well enough against Airbus that they have no need to make another "bet the company" investment at this time. A commercial BWB development would be just that. With A-380 development and certification taking a serious stumble this year, and hundreds of customers NOT lining up for the A-380, Boeing made the right choice to focus elsewhere.

Instead, greater efficiency is winning over customers. The 787 is an extremely hot seller, and a 747-based competitor for the A-380 has emerged in the 747-8. They're applying the propulsion system advances from the 787 to the 747 to result in a much more efficient jumbo jet. You can read more here:

Don't be fooled by fancy Photoshop images. Be inquisitive and dig deeper!

Why not make the engines more aerodynamically mounted into the structure, at least faired in better than this artists attempt? It looks like a Zagi with three speed 400 motors mounted on the back.

Rant over.

I'm sure we'll see these sorts of designs in the future, as soon as the paradigm of the aluminum tube goes away from the engineer's mindset.

Don't get me wrong I plan never to get on one - too many bodies in one place for fate to slam down BUT the a380 definately has a future and boeing are way way way behind now they have scrapped the point to point concept.

Just my point of view don't beat me over it ayy

Status: offline 		Ah guys, this has been floating around for quite some time. I don't believe its anywhere near real - see:

http://www.truthorfiction.com/rumors/b/b797.htm

The BWB concept has the benefit of increased efficiency, but it also has a lot of disadvantages - pressurization stresses, uncomfortable ride for those in the center with no windows, and those on the ends with the roll effects, *more* of the infrastructure difficulties that the 380 faces, and the general public perception of flying on something so different. These and other issues, would result in the development costs for a production airliner based on BWB making those of the A380 pale by comparison.

In addition, there have been ethical questions reaised, and I think rightly so, about placing so many people in a single aircraft and the effect it will have when one of them is lost. I personally, don't think you'll see A380's flying in this country (except for perhaps international routes) for quite some time. I certainly don't want to ride on something that big, particularly one made by Airbus, and I think many travelers will feel the same. The A380 is made to ply the long haul routes to/from Asia and I think that's where it will stay for awhile...

That is true, but "The A380-800 can seat about 880 passengers in a one-class, high-density configuration." That's a good 300 more than the 747-400 and I'm sure that it will be used in that configuration on some routes. There's still doubts that you can even get that many people off of the thing in the required 90 seconds and its going to be a heck of a mess when one has a problem. Aren't there better ways to raise per-seat efficiency than cramming that many people into a 600 MPH missle? Cargo is one thing, but do we really need to save $50 on a flight of 6000 miles? Heck we can't even get people in this country to stop driving monster 9-passenger SUV's with one person in them and that would save billions more!

But look at all the Jobs created because all the airports will need new runways and terminals. The runways will have to be longer and MUCH thicker to handle the weight! The terminal waitiing areas will now have to hold 500? 800? no 1000 passengers! All to walk the one jetway single file! Oh the Humanity!

i never completely understood, why did they use pusher props to power that thing, wouldnt it look abit more scale if they used edf's or something?

Status: offline 		Hi
I saw a report in an American modelling magazine about Beoing's blended wing experiments several years ago. I think eventually the industry will be forced to go towards this type of aircraft. Global Warming is a fact and the aero industry is currently the biggest rising contributer to this problem. So this alone will force the consideration of these designs. I was surprised the Airbus went for the big tube design but frankly I think the days of these type of aircraft are numbered.

Remember it was 1997. The model was huge and that size edfs were really a dream at that point. Turbines were just coming on line at that time, but there really was no need for turbines for this kind of project.

Status: online 		I think it will be loooong before we actually see one fly. Investments for such projects are way beyond those for the A380. Project was recently given new momentum because they finally succeeded in flying a scaled down model of the blended wing. There had been some trials before but they were total failure. I seem to remember there were three pilots at the controls . Hopefully onboard computers will help one day.

Interesting to see how apparently misaligned these exterior engine pods are.

::edit:: i think its an optical illusion, the pods are parallel but the plane is so curvy that nobody can see which direction anything on it is pointing...
