Boeing 797 To Be Blended Wing

Tue Apr 25, 2006 1:18 pm

Forgive me if this has already been posted. I did a search and couldn't find anything dealing with it.

Boeing announced that their 797 is going to be a 1000 passenger blended wing plane to directly compete with the A380.

It looks alot like a really big sonic cruiser to me. Is this brand new information? This is by far the first I've heard of anything like this. I thought the 797 was going to be a replacement for the 737 in the low to mid 100 passenger market. I thought the 808 would be maybe a 773/748 replacement, but was subject to seeing the success of the A380. I am not toally convinced the A380 will be a success, and certainly not with 2 aircraft designs in that niche market. I appreciate the post, but forgive my skepticism about the information.

Seeing as it appears in Boeing's old house colors, I'm thinking this is an old design (it reminds me a lot of an old McDD blended wing-body design I saw a model of a few years back). I don't see it happening. Besides, I was also under the impression that the 797 was going to be the 737 replacement.

Please you have got to be kidding. The B797 design would have to be IMO even more uglier then the A380, let alone totally costaphobic (sorry about the spelling) for the middle row passengers. No way in hell would Boeing even build that. There is no need to build an A380 competitior yet because only a select few airlines will require a 550+ seater, hence the so far confirmed orders

This is hard to believe. Boeing has not released this information on its own website. Was that article written by a high school student? Did Boeing all of a sudden drop the 747-8? The 797 will not be a blended wing seating 1000 seats. Love how the pictures are in 1990s Boeing in-house colors and not in the new colors.

As discussed here. The blended wing has advantages, but for the passengers...not the best option. Those in the center seats would be okay but if you are in one of the outside rows and the plane banks...bye bye luggage and lunch.

I thought blended wing designs for commerical aircraft would produce uncomfortable rides, mostly for the passengers further away from the center longitudial axis.

It is true that Phantom Works has been researching such a plane. However, it is still very much a back room side show along with hundreds of other projects, the vast majority of which will die in quiet obscurity. Nobody except the authors of the article call the BWB a 797. That name makes it sound like it will be offered for sale tommorow.

They make similar misleading statements about other new technology products. They put things ready to market next to things that are barely even being planned, and do nothing to tell the reader the difference. That is misleading and sensationalistic.

Hey! You bring an important point here! Since NW has started charging for emergency exit seats, why not maket these seats as... oh... say "stabili-seats". YES! For an extra nominal $199+fuel surcharge-of-the-day, you can get your own center seat featuring almost no rocking whatsoever! Nice!

Yes, it is a very, very old Sonic Crusier design, the latest Sonic Cruiser (before Boeing dropped it) looked in fact considerably different.
Blended body is not such a hot and desirable design as originally thought - those who read FLYING magazine know what I am talking about. There was a highly technical article on this topic.

Boeing's next two projects are Y1 and Y3, the Y1 being the 737RS, and the Y3 being some long-term 747 / 777 replacement. Since the 747-8 is still under development, the Y1 will obviously come out long before the Y3. Y2 is the 787. The whole Y1-Y2-Y3 series is Boeing's plan to simplify its offerings into three basic types, narrowbody (currently the 717 and 737, and until recently the 757), small widebody (currently the 767), and large widebody (currently 747 and 777).

One inherent design problem with these flying wing designs is the safety issue of how to evacuate all the passengers in an emergency. It would probably have to have more than 5 aisles which is an awfully long way from the exit if you are seated in the centre.
Its like the problem with building extremely tall buildings. One of the main easons that it is not economically feasible to build mile high skyscrapers is not that they are difficult to build, but that The more floors you add, the more the lower floors are good for nothing but gaining access to the upper floors & providing services like water plants, electricity stations etc.
In its original studies for the A380, Airbus examined the possibility of mating two A340 fuselages side by side but rejected it on safety grounds related to evacuation issues.

If flying wings were that great then they'd be flying passengers now. There are a number of problems for the manufacturers, the biggest being that it can't be a family aircraft with different length fuselages (though the 747-400 is the exception). I think the whole concept is restricted to a particular size of aircraft and that's big. You won't get a flying wing replacing the B737/A320 series, or the B767/A330 series so it's only a huge aircraft that will work. And is there the market for this and the A380?

The engines can't be buried on an aircraft such as this because, being at the back of the aircraft, the incoming airflow would be awful (due to the fuselage boundary layer.) So thay have to be on pylons. I can't imagine having B2 style intakes at the leading edge either, especially for high bypass engines.

There is the issue of airline psychology. The history of civil aviation has been that of a long tube with wings on the side. A flying wing is just too different for any airline to risk investing, especially with the likely costs involved.

There are also other issues such as the passenger psychology of being in a closed box with very few windows and, as pointed out, the evacuation arrangements.

The engines are out of the body for good reason - first, if one explodes, then the damage is away from the wing. Blended in the wing, this would make the plane vulnerable. Second, the design pulls air over and under the wing, helping to create lift.

Quoting Oly720man (Reply 21):

There's already a middle section in most aircraft away from the windows. It wouldn't be that different. Also, "synthetic" simulated windows could be installed, namely large monitors in the back of each seat, with views of the outside provided by installed exterior cameras.

With all the space provided by the blended wing, this opens up new possibilities for arranging seats, other than the row arrangment seen in the previous designs.

What's not mentioned is that this design can be tweaked to make the ultimate "combi" arrangment, leaving airlines to mix cargo with passengers.

As for escape routes, emergency stairwells could be installed from the passenger deck through the top of the aircraft, as well as the sides.

I don't believe that this is a serious design that will be offered by Boeing, but it's fun to look at again and explore its potential.

This can hardly be true. First of all, didn't Boeing announce themselves, they were'nt even going to look into developing a plane bigger then the 748 for the next 10 years?
Anyway, I thought Boeing stated the 797 is going to be a 737 secessor, that would make so much more sense.
At last but not least, the image is in Boeing's old house colors, which just showes it IS old news.

It is indeed true that Boeing/Phantom works/Nasa have been studying this concept . However , I doubt very much that this is true at this time .

I believe Boeing would 1st try the BWB in a military a/c " tanker/cargo a/c " then if all went well , they " Boeing " would construct a smaller commercial BWB aircraft .

If this was a real announcement from Boeing that Boeing's next big plane would be a BWB , I feel the news would have been all over the place . Can't find anything other than all the old threads on Google from before .

Nothing to indicate Boeing is going BWB at this time . cry

http://en.wikipedia.org/wiki/Boeing_X-48

The X-48 is an experimental aircraft currently under development by Boeing and NASA for investigation into the characteristics of Blended Wing Body aircraft, a type of flying wing.

Test flights were scheduled to begin in 2004, but no reports were ever made of them occurring, and Boeing indicated in November 2005 that a new model (dubbed the X-48B) was being built. The same annoucement also revealed that the United States Air Force had become involved in the project.

Anyone care to guess how much work would need to be done at airports to accept this aircraft, if it existed? I don't think the ramp area at most airports could accommodate that very easily with current equipment and jetways, not to mention gate areas would have to be significantly redesigned to deal with that many pax.

In general, it's preposterous.

My guess would be none, its the same wingspan as a 380 and it has doors just like any other plane. To say this is preposterous is like saying the A-389 is. Is that your argument?

I believe the A380 is using two jetways for disembarking, and with this proposed unit, the flared design might make that more difficult that a "traditional" shaped aircraft. Sure you can use one if you want, see how happy the pax will be.

Airports have evolved into efficient machines for servicing the type of aircraft they see currently. By introducing a radical new design, it means all the equipment used to service them would have to be examined to see if it makes sense. What about getting food to the rear galley, if located in the middle of the plane? What about the engine location? What about cargo belts? You're saying it will all work no problem with a completely different shaped aircraft? I don't think it would be quite so seamless. It's not all about wingspan.

It wouldnt be seemless, niehter was the 380. But, I seriously doubt that anything you mention would be a problem. The guys at Boeing and Airbus are pretty clever. As far as jetways, I absolutly disagree, they articulate just fine and why wouldnt Boeing look to the facilites for the 380 anyway?

If you really look at it, the front is not that different than current designs, its the wings that are different.

First thing I thought of when I read this thread was that pic from a popular mechanics magazene I used to have.

That article is... dumb. No direct quote. Sounds more like a 16 year old doing an article on the BWB he just discovered and named it the 797.

”This is a great advancement in commercial aviation and a huge win for boeing"

Who the heck are they quoting there? Proably the same kid who wrote the article.

Last thing I heard about the BWB is that they still dont have a way to pressurize a non-tubular structure. The design is basically the same as a B-2, but the B-2 only has a small pressurized structure.

The only disadvantage I can think of is that most seats, if not all seats, will not have a window, or even see a window. It wouldnt be praticle to put seats near the fusulage walls cause in a banking turn those people sitting in that area would be subject to a very steep roll angle.

They cant pratically make tube aircraft any bigger than the A380. A BWB can stay in the footprint of a A380, and be so much shorter.

So this in fact has been kicked around by Boeing's think tank Phantom Works for a while.

However it just a concept and there aren't any firms plans to do anything with it. It was even thrown around as a possible tanker solution at one point I think.

In other news, Bombardier and Embraer had joined together in an unprecedented move to corner the intergalactic fighter aircraft market, with a new generation X-Wing prototype:



Yoda, president of the jointly created Bombardier-Embraer Intergalactic Vehicles Ltd., cited the need for intergalactic cooperation to preserve the integrity of the galaxy.

Quoting Phuebner (Thread starter):
Boeing announced that their 797 is going to be a 1000 passenger blended wing plane to directly compete with the A380.

Boeing hasn't announced anything...

1,000 passengers? I'd rather take a boat.

The whole project was shelved long ago, IIRC, it was more of a feasibilty study than anything else.

One thing I've learned is to never believe anything from things like Popular Mechanics magazine or similar "tech" websites, 99% of the time its all hype and BS.

Quoting Oroka (Reply 39):
They cant pratically make tube aircraft any bigger than the A380. A BWB can stay in the footprint of a A380, and be so much shorter.

"You'd be daft to think that any airline would want anything more than 2 engines. Think how complicated that would be! And how would they evacuate all those people if it had a belly landing? Particularly if that crazy nose wheel failed. No, I can't see anyone needing anything bigger or more revolutionary than a DC-3. Look at the proof, airlines are ordering them in droves."

The article says:
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.

But the 747X program was cancelled in 2001, and the Phantom Works is in St. Louis. Boeing kept people in suspense over whether they would rename the 7E7 to 787 (or to something else), so even if Boeing were to announce that they were going ahead with this airliner, the 797 designation is premature. Anyway, Boeing has repeatedly said there is not a big enough market for such a large plane. This is not a credible report. This BWB is also not related to the Sonic Cruiser.

Quoting Aviationfreak (Reply 29):
How are we gonna load baggage and cargo on such an a/c?

I think the picture posted in reply 30 by DeltaDC9 makes it evident that hatches could open on the lower level to accept cargo. Alternatively, a cargo ramp could drop down from the rear end.

Quoting Oroka (Reply 39):
Last thing I heard about the BWB is that they still dont have a way to pressurize a non-tubular structure.

It can be built like an air mattress, with tubular passenger bays separated by lightweight, mostly-open shear webs. Where the webs join the top and bottom, material is thickened, so that the external concavities can be smoothed over, as they are for the 380 and 787 where the bubbles join at the floors.

The BWB is indeed a real study, but, I dont think it will happen.

This article is not only old but unreliable and written more in the style of a supermarket tabloid than a professional news article.

So this is no "announcement" from Boeing...unless it comes from Boeing or SeattlePI, don't take it as the truth.

This is a reheat of an ancient powerpoint presentation... It would be an amusing about-face if Boeing were to suddenly decide there's a huge market for 1000-seaters after all.

But as earlier posters said, Boeing hasn't actually announced anything.
