The definitive MD-12 was very similar to the Airbus A380. I can't explain why the MD-12 wasn't launched while the A380 got the nod only a few years later. Perhaps Airbus just had a more aggressive sales team.sferrin said:I was really hoping to see a 3-engine MD-12. IIRC it was suppose to be powered by 3 90,000lb thrust class engines.
It would have been bigger than the 777. The MD-12 was suppose to be bigger than even the 747.Matej said:Maybe it could look nice, but I think that this design doesnt have a chance against Boeing B777. Since the time when two enigned planes can fly cross Atlantic ocean, three engines are obsolete.
It's been a while and I'm going strictly by memory but I could swear even the 3-engine one was suppose to be bigger. As I recall it was suppose to use 3 90,000lb thrust engines and been sized accordingly.Matej said:Wait. Are you speaking about early, 3 engined MD-12, or later four engined project, that had the same designation? I said this about three engined MD-10 successor.
Just ran this down. Said it would fit up to 515 passengers.Matej said:Interesting. I dont have any data about this proposals, only from pictures it looked to me as like B777 sized.
Really simple, to the McDonnel boys in St.Louis the Douglas aircraft division was just there to generate cash flow, thus the concentration on derivatives rather than new designs...which doomed the commercial end of the business. The same mindset infected Boeing for a few years after the merger...thankfully it passed.TinWing said:The definitive MD-12 was very similar to the Airbus A380.

Observe the cross-section!flateric said:more stuff
See "McDonnell Douglas MD-11 Twin"V8Interceptor said:I've never seen any documentation of a proposed twinjet variant of the MD-11...that would seem to be a logical development and MD did do design work on a shortened twinjet DC-10...
Better scans of that pictures can be found in the web that flateric posted earlier in this topic: http://md-eleven.net/MD11-MD12-undeveloped-modelsTriton said:Artist's impression of McDonnell Douglas MD-XX Stretch circa 1996.
That picture's filename suggests it's a small version. Any chance of a larger?circle-5 said:Both these models are at the same scale. The MD-12 nearly had a 10-year head-start. Very sad.
The vital numbers for size:sferrin said:I love that MD-12XX Stretch. Graceful like an A340-600 and not a wallowing whale like the A380 and most others.
Both are subjective. As I said I like the MD-12XX Stretch and the A340-600.chornedsnorkack said:The vital numbers for size:sferrin said:I love that MD-12XX Stretch. Graceful like an A340-600 and not a wallowing whale like the A380 and most others.
MD-XX stretch: 71,2 m long, 6,02 m wide and high
A340-600: 75,3 m long, 5,64 m wide and high
B777-300ER: 73,9 m long, 6,20 m wide and high
A380-800: 73,0 m long, 7,14 m wide, 8,56 m high
Which of them would look better?
Which of them would you rather fly?
Triton said:McDonnell Douglas studied improved, stretched versions of the MD-11 trijet, named MD-12 and MD-12X with a possible lower-front passenger deck with panoramic windows. The McDonnell Douglas Company (MDC) board of directors agreed in October 1991 to offer the MD-12X design to airlines. MD-12X had a length of 237 ft 11 in (72 m) and wingspan of 212.5 ft (64.39 m).
How different was MD-XX from MD-12X?Triton said:With the MD-12 program over, McDonnell Douglas focused on 300-400 seat MD-11 derivatives. At the 1996 Farnborough International Air Show, the company presented plans for a new trijet with high-seating and long-range it also named "MD-XX". The MD-XX was offered in two variants; MD-XX Stretch with a longer fuselage and MD-XX LR for longer range. Both MD-XX variant designs had 213 ft (64.5 m) wingspan, the same as MD-12. The MD-XX Stretch was lengthened 32 ft (9.7 m) over the MD-11 and had seating for 375 in a typical 3-class arrangement and 515 in all economy seating. Its range was to be 7,020 nmi (13,000 km).
