What Was The Name Of Boeing Three Aisle Airliner?

Tue May 31, 2011 3:13 am

In 1999 to 2000, Boeing had a concept three aisle airliner that use a 777 section 42. The a/c looked a big sister to the T-7, like the 767 was to the 757. The a/c had four giant engines and carried around 480 passenger in a three class lay out. I know this concept is over and gone, but I would like to copy a drawing of this concept airliner, but I can not remember it's name, so could somebody please help me out?

I think this is your plane....

Funny, googling shows a lot of double deck concepts, but I seem to recall A-343 proportions with a really wide main deck...

Let me know what you find!

747-8.   


Not but seriously another three aisle concept from Boeing was the infamous "Hunchback of Mukilteo", AKA 767-X.

The aircraft you are looking for, 747400sp, is the Boeing 763-246C concept.

Speaking of VLA's, wasn't Airbus first thought for the A3XX (later A380) to basically put two A340 fuselages next to eachother and weld em' together?

Does anyone else remember this or am I mistaken?

Yes, Airbus had a number of proposals for aircraft with side-by-side cabins within a larger fuselage structure, but these predate the A3XX (which looked very close to the A380).

Was the 747-700X intended to have three aisles on the main deck? It was a 747 derivative with an enlarged 777-ish wing and a widened fuselage incorporating a twin-aisle upper deck.

The 747-700X would have had a 1.5m wider main cabin (7.6m total), so I can only guess that they would have gone three aisles as you would not need 1.5m to go 3+5+3. However, I have never seen an internal schematic of the 747-700X nor does the information I have on the plane note the internal configuration, just that it could seat up to 650 in three classes.

As mentioned, this was one of the proposals. However this structure would have been much heavier than the 380 vertical ovoid and was thus rejected.

Here is a picture of the Airbus UHCA:
