McDonnell Douglas DC-X-200 project

[hesham]

Hi,

the MD DC-X-200 was a project of twin engined version
of DC-10.

Proposed wide-cabin jet transport under study in Long Beach was designated the DC-X-200. A twin-engine aircraft, the DC-X-200 was proposed as a replacement for narrow-cabin short-to-medium range jetliners. As envisioned by McDonnell Douglas engineers, the twin jet would carry about 200 passengers in a cabin almost 19 feet wide, same as the DC-10. Fuselage would be 140 feet long, and wingspan would be 150 feet. Tail height would be 52 feet. Advances in the DC-X-200 would include a supercritical wing and advanced high-lift system. DC-X-200 would offer considerable improvement over narrow-cabin jets in terms of fuel economy, passenger comfort, and cost of operation.

The DC-X-200, or Model D-969N-18D/18F, was a smaller aircraft that was proposed when the DC-10 Twin was rejected by airlines as being too large and too expensive to operate. Airline surveys in 1972-1973 indicated that they were more interested in a wide-bodied twin with 180 to 200 passenger capacity. The aircraft was designed to compete against the Airbus A200B and replace the larger Douglas DC-9 and Boeing 727 aircraft.

The DC-X-200 was aimed at the then airline capacity needs, with interior arrangements in a mixed class version for 18 first class passengers and 180 economy class, for a total 198. There was also a high density seating arrangement for a total of 226 passengers.


The cockpit, forward fuselage section, aft fuselage section were identifical to the DC-10. The DC-X-200 would differ in wings and engines to the DC-10. The supercritical wing would be brand new based on the development of the YC-15 Advanced Medium STOL transport. It would allow higher cruise speeds while at the same time having greater lift potentinal in the slow speed range. Greater lift would allow the DC-X-200 to operate at shorter airfields in smaller communities.

Here are some manufacturer desk models of the DC-10 Twin (DC-X-200) and Lockheed L-1011-600 BiStar.

I presume that the Lockheed L-1011-600 BiStar was the 220-to-230 passenger medium range version of the Lockheed L-1011 Tristar. The DC-10 Twin had a seating capacity of 265, while the DC-X-200 had a seating capacity of 198.

In mid-summer 1978, Douglas announced it was canceling the DC-X-200 project. In addition to the 220-to-230 passenger medium range version of the Lockheed L-1011 Tristar, Boeing had announced its 767-200 transport with orders from United Airlines and a sudden upsurge in orders for the Airbus A300 and its successor A300B.

Another report gives the DC-X-200 as the Douglas Model D-969N-21, and also provides the designations used for the NASA 4.7 percent scale model:

http://ntrs.nasa.gov/archive/nasa/casi.ntrs.nasa.gov/19840025332_1984025332.pdf

The wind tunnel model was a 4.7-percent scale representation of the DC-X-200 airplane configuration. The model was designed and fabricated for testing at high Reynolds number conditions at the NASA Ames 12-Foot Pressure Wind Tunnel. The model designation was LB-486A for the Ames test and LB-486C for the NASA Langley V/STOL test.

Re: DC-X-200 Brochure

That looks like a later iteration with a higher-aspect ratio wing; interesting to see how the main undercarriage is stowed at an angle to reduce the length of the main undercarriage bay. Did you win the brochure Mark?

Hi Terry -

I'm passing in this - hope Scott obtains it.

[Graham1973]

I have recently been told that there exists a study into 'glass cockpits' that used this aircraft as it's baseline design. I have just finished searching the NTRS for it but could not locate anything matching the description. If anyone can help with pointers I would be very interested in finding it.
