New Boeing 737 ????

Re: New Boeing 737 ????
Don't expect this to be the 737 replacement. This aircraft is something for the future, the current technology is not ready yet to make such an airplane like it should be.
This: http://www.flightglobal.com/blogs/fligh ... 21875.html or this http://www.flightglobal.com/blogs/fligh ... 91612.html has more chance to become the new B797 (wich is btw not a direct 737 replacement but more a B739/B757/B762 replacement).
The first link is a picture of a NASA presentation last week (or two weeks ago?) about future aircraft materials and this is one of the slides wich was provided by Boeing. The aircraft on the picture is a twin aisle with a capacity of around 215-230 seats. The second link is another patent of Boeing wich shows a short twin aisle design. Boeing has a lot of patents for a short twin aisle design.

Re: New Boeing 737 ????
I am going out on a limb and I predict this IS the 737 replacement.
Boeing needs to make a bold leap again to superseed their own 737 (whihc is abut 8% more econocil overalland at least 3-4% better than the curretn A320 for fuel burn). They also need to not only supersede the A320NEO, but offer something it does not.
It needs to be a smart use of materials and a configuration that offers more benefits.
A mini wide body gives them the benefits (it may be a bit slower to acomdate fuel burn but on the typicl LCC stage lengths thats minor). Trans Atlantic can live with that for what it offers.
With the GTF ovffering contiued fuel improvments over time (1% per year per P&W) it has huge upside in fuel burn on a very efficient aircraft.
Boeings EIS for this aircraft (currently) ias 2019. That gives them plenty of time.
I think the mini wide body allows them to spin off (pun intended) the benefits of the compsoite fuselage from the 787 (not even same process but the larnign curve using them), and a mini wid body justifies their use.
I think the wing will be alumnuin alloy. A lot easier to work with, not as much investment (allows them to upgrade the wing in the future to either a composite or anohter better alloy type). The wing takes a beating and composite have to be thick enough for that, ergo right now composites are not a good choice for an aircraft this size aircraft (I think the 787 would have been better off with an aluminum alloy wing as well).
By the time open rotor is here (its alwys 15 years away) the GFT will have increased the eifficney to the point its a mute (staright across let alone the nutty mouting work and one off engine offering as you cannot mount someone elses open rotor on the same mount).
The mini wide body also alows Boeing to tap back into the 757 marekt, and at teh same simte as small as 89 seats. What they do below this is probly contiues 737 produciton.
As that market keeps shifitng up in size (for inteconitanla and cross Atalnat range) I think Boieng gives it up and partners with someone like Mistusihih to fill that lower end.
I also predict the two engine offerings will be the GTF for sure and RR (less certain, but they have a new engine in the works, the LeapX has no upside in it, aboslutely maxes out existing and would only get minor improvement in fuel burn as time goes by)

Re: New Boeing 737 ????
RC20, it seems you think a small widebody will be the B797 (I'm not saying 737 replacement as the B797 will be more a B757 replacement and not just a 737 replacement). And an aircraft wich can fly transatlantic. And I aggree on that. Many people think a small widebody will become the B797 and Boeing has plenty of patents for such designs.
But do you really think the design like shown on the patent (link first post) will become the B797? The two links I gave you are much more likely.
The two later links are also short widebody's with composite materials, new fuel saving engines, ... AND they are much easier to build at this stage.
IF Boeing is going to launch a B797 it will probably something very simular to the aircrafts shown on the two pictures in my previous post (two flightglobal links). An aircraft with another wing/tail configuration is something for later (and probably it will be a long haul aircraft before it will be a short haul one). So if Boeing will make a B797 with EIS 2019/2020 we will probably see some kind of small 787.

Do you think 8 years is plenty of time to build/test/deliver an aircraft like that? Do you reallize Boeing is working on the B787 since about 2003/2004 and it is still not delivered. And while the B787 is an aircraft full of new technologies, it can not be compared to the chalanges Boeing will face to build an aircraft with such wings/tail/... And you think 8-9 years is enough to build an aircraft with such a wing/tail configuration? If you mean that, I think you are dreaming. The design like shown in the patent (first post) is something for the future, something like 2030 (like Airbus is also saying btw). The technology wich is currently available is just not enough to make such an aircraft to a succes. Without doubt Boeing would face enormous troubles wich Airbus will not have as they will see what happens with Boeing. Boeing is not going to take that risk now. Another important thing is the financial side. Such a program will cost so much money that it could kill Boeing (Commercial) when it goes wrong.RC20 wrote:

Re: New Boeing 737 ????
I did not look at the patent in the first one.
No, it will be the one from your links.
Sounds like they will not announce at Paris air show, just some more details. Details of exactly what Boeing said meshes with that. A lot for Boeing to commit to. More details but not a formal launch.
Biggest issue mfg wise is how to manufacture the fuselage in quantities needed and at a cost that works. That would be the next composite technology they have to mature. Possible they would do it with an advance aluminum alloy. That would be the pacing item and likely do not know enough yet what might work to move on it.
