Hi all
Good news for Boeing, Korean to buy 5 passenger 747-8's. Here is the link to Airliners.net

How many airlines are confirmed buyers now?
I belive Lufthansa were going to be the launch customer, is this still the case? ------------- Jazz that's not a drawer its a trash compactor. And when Uncle Phil sees this it'll be a Jazz Compactor |

Yes Lufthansa are still the launch customer, just the 747-800 is proving to be a hot seller for Boeing. ------------- http://forum.mutleyshangar.com/viewtopic.php?f=4&t=3698">

| 748 looks a great aircraft. When will it be in operation? |

Five new orders does not sound a lot to me. I wonder if the programme is worth being continued (for pax operations atleast) seeing as Lufthansa and Korea are the only customers and it has taken a long time for this order to develop. ------------- Concorde216 "All modern aircraft have four dimensions: span, length, height and politics.

Demand for the 748i depends on how much need there is for an aircraft between the 773ER size and A388. Saw an interesting chart in Airliner World at some point showing demand for each aircraft size until 2020. If anyone knows which one I'm talking about, please post it. -------------

Lack of orders is hardly surprising when even the largest airlines are currently laying of many staff and in worst cases fighting to exist. It'll pick up again, and I suspect a lot of orders will come in from existing 747-400 operators as their airframes get older and sold on. |

I think maybe if Boeing had launched the 747-8 sooner, say just after Airbus luanched the A380. The 747-8 would have generated more sales. Boeing had already the basic design on the drawing boards. |

Lufthansa are going to use the 748 in between the A346 and A380, when the Director had the interview with Airliner World it wasn't very specific on what the director meant, but i think it more to do with pax size, so instead of sending 250 or 500 people to one destination they fit the number between that with the 748,
does this make sense or am i talking gobbledegook?

I'm not too sure. If existing 747 customers are going to buy the -8i why didn't existing 747 operators Air France, BA, Qantas, Singapore Airlines or Virgin opt for the 747-8i? The A380 is a more efficient aircraft to operate than the 747-8, otherwise BA (for example), would have stayed with Boeing and ordered the -8i. I would not have thought it would be justified, to have a such a small gap between aircraft like the A340-600 or 777-300 and the A380, filled by an aircraft like the 747-8i (which is what Luftansa is planning). ------------- Concorde216 "All modern aircraft have four dimensions: span, length, height and politics.

Here is a link of some nice pictures of the 747-8. From the Boeing website.

I think Boeing will fly the 747-8 before year end. Engine runs already completed.

Okay Edward, you were right. No flight of the 747-8 this year, maybe 2010
uh, no this my 666 post!

I think it will fly before this time next week, just a hunch.

There is a rumour on a.net that it will be on the 10th (Next Sunday), however in Boeing internal systems it is not the 22nd (pushed back from the 21st as Kieran stated).

Anyone noticing a new pattern in wing design. Look at the 787 and the 747-8. They both have more of an upward sweep with a slight angle increase at the tip of the wings. Anyone know how this would be aerodynamically different from the standard winglet design?

The 77W, 77L and 77F also have them, as well as the A350.

Ah. What do they do for aerodynamics and performance?

Reduce fuel burn. I don't know if they affect handling much, I would guess not really.

Well it looks like I was wrong, thought there was a good chance of the 747-8 flying today.

The latest on the 747-8 program, not much news onthe first flight though.

Winglets can have a dramatic effect on handling, especially at low speed. On the Fokker 50 they make the difference between having roll control and not having roll control! Without them the ailerons stall. Best regards, Vulcan. |

Very interesting Vulcan, I've flown many times on the Fokker, yet never noticed they have winglets.

That's not strictly true, as the basic wing of the Fokker 50 is that of the Fokker 27, which didn't have the upturned wingtips. I suspect it does have certain efficiency benefits for a fairly basic inefficient straight wing design though. |

My info comes directly from guys who flew it. Without the winglets, the aircraft is uncontrollable in roll at low speed. The wing is *based* on the F-27, yes, but it is quite different. Best regards, Vulcan. |

How do I answer this ?
Firstly ailerons do not stall, it that part of the wing that stalls(forward of the ailerons). If you have a look at the wing design on light aircraft(Post 1940's), the angle of incidence is greater inboard of the wing. Therefore the inboard part of the wing stalls first, but the outer part of the wing is still flying, giving aileron control as the angle of incidence is less. Also known as washout, sorry have I not explained in detail. Will find a link to explain fully.

Not convinced at all. For a start it wouldn't get certified. They'll improve the handling yes, but to be uncontrollable? They really must've been using a figure of speech as opposed to talking literally. As for the wing, from what I can gather, aerodynamically it is identical other than the mounting for the (different) engines, and the endplates. |
