Dubai Air Show 2013

I had the impression that the 777 wing was largely not changed, only the folding part is new and will be composite.
The much larger wing span (and aerodynamics on that portion including the tip) help the efficiency of course.
The numbers vs. “competing aircraft” are absurd, especially when you consider its supposedly +16% better than current 777,
saying it is 12% better than 350 is absurd and is likely comparing apples to oranges…
Consensus seems to be that the 777-8X will be somewhat worse vs. equivalent seat 350, although it will have it’s ultra longrange niche.
777-9X doesn’t have any competing aircraft, unless one considers 747-8 😉

Airlines dont’ believe this kind of PR bull****, I don’t see why anybody else should…
Boeing always wants to make things out as a black and white battle of total domination (that they will clean up everything).
Wake me up when that actually happens.

I can only assume with the likes of Emirates they’re stealing a march on the Asian carriers.

It’s no secret that demand for air travel in Asia will soar over the coming decades, I can only assume the Middle Eastern carriers are setting up shop early to swallow up the market before the lumbering Asian airlines have a chance to catch up… That’s fine, assuming the Asian governments just stand by and let the Arabs walk in and take their home-grown airline’s customers from their hands.

I doubt it will be that simple though, let’s not forget who buys (or will buy) the majority of Arabian oil over the coming decades. Best not bite the hand that feeds you… Politics, politics and some more politics are the order of the day, and the key to the Emirate airline’s growth.

I agree…what in the world do those airlines plan to do with that many aircraft? That’s almost one aircraft per destination for some of them when you look at their whole fleets….seems a bit brash to me.

Those orders are mental! With the Emirates order, it looks like the board just said: “Here’s $100 billion, buy as many planes as you can with the money!”

Thanks Amiga500. Explaines things very well. One question though is the huge range of the 777X, how many airlines need it?

Iraqi Airways:
5 Bombardier CS300 – valued $387 million with options for 11 more planes.

Please excuse my thickness, how does the 777X differ from the 777?
787 wings and engines?

Using new wings and engines based off 787 design principles.

Fuel burn will be 10% lower than on the GE90-115B-powered 777-300ER, while the GE9X should have a 5% lead in specific fuel consumption over the Rolls-Royce Trent XWB engine on the rival Airbus A350, says GE.

“The -9X will have a 16% to 17% delta in fuel burn (compared to the current 777-300ER), and is an aircraft that is redesigned inside and has a new wing,” says Emirates Airlines president Tim Clark.

Obviously, reading the above; the numbers are not consistent, but they could imply a (fuel burn equated) drag reduction of 6-7% on the 777-X. I also seen wild claims vs. the A350-1000, but these seem to have been withdrawn. Someone must have got a bit ahead of themselves before others seen sense and had stupidly optimistic performance claims retracted.

Of other interest is that Boeing are intending to use a folding wingtip on the 777X to improve aspect ratio and with it L/D. It will no doubt be a significant factor in the aerodynamic performance of the wing; so is pretty crucial they can actually pull it off.

edit: Seems it wasn’t pulled from everywhere:

“The airplane will be 12 percent more fuel efficient than any competing airplane, necessary in today’s competitive environment.”

The above of course implies that the A350 wing is no more efficient than the existing 777 wing. Given the A350 is benefiting from the reduced t/c allowed by the composite spar (relative to the existing 777 metallic wing) and 20 years of advances in computational hardware and CFD techniques, that is highly speculative*.

*feel free to swap in ludicrous at the reader’s discretion.

Economies of scale only work so far, let’s not forget our long diseased behemoth Pan Am who is testament to this theory.

I wonder how long it will be before we’re all flying LHR-JFK (via DXB, AUH or DOH)…:p

It’s funny you should say that, whilst I was looking for flights from Amsterdam-New York; the cheapest option was to fly with Turkish Airlines via IST! :stupid:

Wow, that’s almost $200bn worth of orders…$170bn of which comes from the x3 major Middle-Eastern carriers (EK, EY & QR); they are certainly a formidable force when you look at stats like those above.
