Boeing 797 details
New Tech Spy has an interesting article about Boeing changing its design from the old fashion technology that the Airbus A380 uses to a more modern Blended wing design used in air force fighters. It looks totally sweet and will probably send Airbus back to the drafting boards to redesign its next plane. I can’t wait to fly in the new Boeing 797 of course its so big it probably won’t be able to land in Milwaukee where I live.

That NewTechSpy story is completely bogus and full of gee-wiz assumptions (such as the advantage this will give Boeing over Airbus' A380--completely ignoring the fact that the 797 would take at least 10 to 15 years before it could go into production). Pressurizing a non-cylindrical aircraft body is going to be an engineering nightmare.
NewTechSpy is a weird, lazy site. The oil discovery article up there now is based on a 3-year old story, which makes their timeline references and references to hurricanes Katrina and Rita completely bogus.
Fascinating Science fiction. Boeing has a really difficult job catching up with the Airbus and this sort of fantasy will not help. I hope they put an official stop to it soon.
Once the 787 enters service in 2008, Boeing will have caught up and surpassed Airbus and their white elephant.
Give Boeing some credit... Do you really think Boeing is in a holding pattern doing nothing while Airbus builds their glorified 747? This is the same old aluminum technology used in the 707! Brinksmanship is the name of the game and Boeing is wisely letting Airbus commit to this old technology with the A380 while Boeing capitalizes on new technology, aerodynamics and materials. Don't discount the blended wing concept... It makes good sence to me, a former Navy Pilot and 767 Captain.

The new blended wing design of the 979 is a logical adaptation of lessons-learned by Northrop-Boeing in designing, building, and testing the B-2.
Much of the materials, control, and aerodynamics technology has been tested already. The public has seen years of pix of the B-2, and the airlines should therefore have less trouble "selling" them on the new design.
If the marketplace approves of the radical new design, we can all look forward to a big step forward in commercial airplane performance. Airbus will be forced to respond, but they will be starting from wa-a-ay back in the basic technologies required.
Northrup would be so proud. Northrup proposed his "Flying Wing" XB-49 as an airliner in the late 1940's. The same arguments that I have read about Blended Wing vs. Tubular Fuselage sound just like it did back then. The Air Force bought the B-47 and the XB-49 had yaw problems and deadly stall characteristics. The B-47 is the granddaddy of all modern commerical aircraft. With modern materials and computer controls, the Blended Wing will work. It is also an extendible design that could be made sub-orbital easier than a tube body aircraft.

the stink of boeing B***s*** makes nowadays..
i'll only believe this only when i see this in person.
th above comment about presurising a none cylindrical vessel is not only a nightmare its downright playing with fire!
this design has a future a a bomber or cargo aircraft of inanimate objects, but live passenger is another story..
if your seated far from the middle spot then the wing motion will be greater(for wings naturally dips to the left and right in flight)!!
this will be the greatest torture machine for the riding public.
The 797 will never fly, or at least the flight will be a very short one. The design of a delta wing with turbines above and to the rear has a fatal flaw. When the flight angle is above a certain value the turbines are starved of air and stall. This would happen probably on takeoff, but definitely on landing.
"Its different, so it CAN'T be done" .... "but we've ALWAYS done it this way"...."of COURSE the Earth is flat"....
It WILL be done, the imperative of faster, better, fuel efficient air travel demands it- maybe not exactly as depicted but certainly time is ripe for the move away from 1950's technology (please don't compare it to that intrinsically unstable Flying Wing!)
Surely no sensible person would imagine Boeing have overlooked such obvious considerations as pressurisation, passenger comfort, engine air intake, etc? I think not...besides, other developers have done feasibility studies on this concept so I think its more than 'pie-in-the-sky'
Consider also Airbus' recent dramatic losses/cancellation of orders; maybe airlines are more forward-thinking than we know?
For the uneducated the Boeing 797 design is no more than an upgrade of the Northrop Flying wing design of 1947. I have personally talked to the pilots of the original Northrop flying and the aircraft was not difficult to fly and most certainly diid not demonstrate unusual stall characteristics if flown with in its defined performance envelope. I hope I am able to fly in one of these aircraft within my lifetime. As a professional Aeronautical Engineer there is no better, more economical design concept as that represented by a flying wing.
The person that said that engines above the fuselage would be starved of air during take-off and landing never heard of the L-1011, DC-10, or 727. The Number 2 engine draws air, not from the slipstream, but from the suction of the induction fan.
Even flight control surfaces, such as elevators on a DC-9, still work in landing or take-off mode, despite the fact that they are partially shielded by the fuselage. It is control surfaces, like elevators, that need slipstream exposure, not engines. And the blended wing concept has no control surfaces shield by the body.
With a blended wing there's no view from the window any more :-( How will I take photos if I have to fly in one?
The pressure inside the aircraft would be at the MAXIMUM 14.7 psi higher than the outside if the plane were flying in the vacuum of space. While a sphere or cylinder can withstand internal pressure better than an irregular shape like the 797 fuselage, the loads are relatively light and shouldn't be that difficult to design for. If you look closely at a conventional aircraft, the fuselage isn't a cylinder anyway; it is more oval shaped, and the floor helps tie the sides together to prevent them from bulging out. Some vertical ribs or columns would serve the same purpose in the 797. I agree with the comment about the vertical motions that will be experienced by the outermost passengers as the plane banks during flight manuvers. They should pay a premium for the "E-Ticket" ride!!! They would probably build a roll-rate limiter into the (computerized) control system that could be over-ridden if an emergency manuver was required. That was how they solved the original Flying Wing's flight problems as well as the B1's.
I saw a video of the passenger version of the Northrop plane that was made back in the 50's or 50's. The leading edge of the wing was clear windows for passenger viewing. There was a stand-up bar with bartender and lavatories you could actuallt turn around in!
As far as not having a window goes, what can you really see out of a regular plane window anyway? There are still some windows along the outer edge of the passenger compartment, below the wing.
I'm a former USAF R&E and NB2D (Northrop B-2 Division/TRW) employee and now working for Boeing as a Unix Sys Admin (pays better in I.T. than in aircraft maintenance). I can honestly tell you that the 797 flying wing design is something to look forward to.
Something else to be noted:
1) this doesn't fall in line with Boeing's "point to point" commercial airplane strategy. This would fit more in-line with Airbus' Hub-and-spoke model.
2) These pictures are several years old. Boeing hasn't used that livery in years...
P.S. They built two for test flying! Really! Go to this website: Google Image Search Boeing 797 and press the picture in the second row. See full sized image. By the way what city is that?
I find reading all the posts to the Boeing 797 interesting because the article in NewTechSpy is totally fake and so are the pictures. Hasn't any of you seen what computer graphics can do? I expect you believe that the Starship Enterprise is real too. Boeing has come out and asked for people to stop spreading this rumor. They are working on a blending wing design, but only for the military and yes two do exist but they are scale models for testing. I spent years in aerospace at Boeing, Douglas and Hughes and there are always these crazy stories going around. The inernet is just a tool to send out these bogus stories. Why not look at http://www.truthorfiction.com/b/b797.htm before you respond to this trash.

This is a quote from Boeing's own webpage. The 797 pics are fake and so is the plane.
From Boulder, Colorado, Walter brings up a topic we frequently get questioned about: the "blended wing" concept. Earlier this year an image of a blended wing "797" made the rounds of the Internet, and got speculation swirling that Boeing has this in the works.
Is there any truth to the emails showing a blended wing 1,000-passenger concept that is dubbed a Boeing 797? Makes sense that the airline industry would head this direction some day, but it just sounds too good to be true!
Yes, too good to be true, indeed, Walter. Someone was having a bit of fun with PhotoShop perhaps. Boeing is not planning to build a 1,000 passenger commercial airplane dubbed the "797," based on the blended wing body (BWB) concept or any other futuristic concept. It's certainly not in our commercial market forecast, which goes out for 20 years. We think the commercial airplane market favors point-to-point routes, and we're developing the 787 as the perfect match to help meet that demand.

hey guys there,s is a protptype flying, goto nasa they have two.
It is amazing to me the drivel that is on this website about the 797! The concept of BWB has been around for decades. At the present time Boeing has no intention and no "797" in development and they also have no real competitor for the A380. They have their hands full getting the 787 off the ground and the billions and billions of dollars and time needed for developing any new airfames are just not available (unless it's for a new weapons delivery system that can guarantee knocking off Osama!). Some of you TREKKIES should stick to what you know best.
i like your blog ....
