McDonnell Airliner Concept 1961 - T-85A?

This model is in the collection of the Greater St. Louis Air & Space Museum. Not much information with it - only what you see on the tag and the number on the engine.

In going through an incomplete listing of McDonnell Model Numbers (1 July 1974), I have found some information on this that happens to raise some more questions. On page 167 (pages 165 and 166 are missing) I found the continuation of the listing for this model. In the Model Number column is "T-85 (220)", then the Series Letter is "A" - this T-85A matches the number on the engine nacelle. But, Haven't we been told that the Model 220 was the later proposal for the Model 119 Transport? Does anyone have access to pages 165 and 166 of this document?

For what it's worth, here is what I have of the description.

a) WING - 1050 SQ.FT. , SWEEPBACK @ 25% CHORD - 24 DEGREES, DIHEDRAL - 6 DEGREES, THICKNESS RATIO (% CHORD) = 13% (B.L.. 63.0), 9% TIP.

b) HORIZONTAL TAIL - 248.8 SQ.FT. (TRUE AREA), SWEEPBACK @ 25% CHORD = 24 DEGREES, DIHEDRAL = 10 DEGREES,THICKNESS RATIO (% OF CHORD) = 9%

c) VERTICAL TAIL - 208 SQ. FT., SWEEPBACK @ 25% CHORD = 46.5 DEGREES, THICKNESS RATIO (% OF CHORD) = 12%


MAIN GEAR TIRES - DUAL 12.50 X 16 TYPE III. NOSE GEAR TIRES = DUAL 22 X 5.5 TYPE VII. READILY REMOVABLE INTERIOR EQUIPMENT INCLUDES LAVTORIES, LUGGAGE RACKS, SEATS, GALLEYS, COCKPIT DOOR, TRIM AND FORWARD STAIRS.

Hi Mike -

Model 220 was Mr. Mac's rebranding of the Model 119 for the effort to sell it in the commercial market after losing out to the Jetstar. I've not seen any other efforts to re-engine the 199/220 for just two engines (four JT-8Ds would be overkill squared). The only engine change, which did not occur, was the prototype flying with J-34s but the production version being offered with JT-12s.

HTH! Mark
 
The strange T-85 and T-85A designations were definitely associated with Model 119/220 variants/developments, though I'm not too conversant with the subject.

I think you've touched on the answer here. The 220 designation was Mr. Mac's rebranding of the model 119. I'm not sure of the date when the designation change too place, but I'll bet it was after the original model 220 / T-85A idea was dead. The number 220 may have been chosen from the available numbers because, like the 707, 880, 990, it is an easier (sexier) number to say in commercial / promotional copy.

Also. Look at the data from that number list. It is describing the T-85A. Most telling is the mention of 10 degree dihedral for the horizontal tail. There is no dihedral on the 119/220 tail.
 
Throwing out a theory here...

Realizing that the "T-85" and "T-85A" designations are completely outside the canon list of McDonnell designations - could it be that "T-85" was an in-house name for the project - perhaps standing for "Transport - 85 passenger"? Supporting this theory is the observation that the aircraft does look to sized for 85 passengers, just as its' competitors (Trident, DC-9 and 737) were...

By the way, there was a Model 220C configuration with four GE CF-700 engines (aft fan J85).
 
Have you considered the possibility that T-85 and T-85A were Federal Aviation Agency project designations?
 
The FAA would also apply designations to manufacturer's projects? I've not ever heard of this...can you point me to examples or documentation so I can learn more?

Prior to 1967, the then Federal Aviation Agency was the lead agency on or otherwise responsible for a number of aircraft projects including the SST effort. It's possible that the T-85 & T-85A were originally designed to meet a requirement or requirements issued by the agency (a Project Horizon spin-off perhaps?), hence their unusual designations.

As we have an array of McDonnell Douglas airliner-related topics — either very short two- or three- post long topics or long topics such as this one will just about anything in them — may I humbly suggest that the following topics be created?
  • A topic for postwar prop-powered projects (such as DC-7D, DC-7T, Skysentry, Model 1906/A, Model 1940, etc.)
  • A topic for supersonic projects (SST, AST, HSCT, DC-2000 etc.)
  • A topic for double- and triple-deckers (D-918, D-956, D-974, LR-600, MD-12, etc.)
  • A topic for DC-8 derivative designs (Model 1920, AWACS proposals, DC-8 tanker)
  • A topic for DC-9 derivative designs (ATJS, LRAACA, etc.)
  • A topic for DC-10 and MD-11 derivatives (MD-100, DC-10 Twin, MD-11 Twin, etc.)
There could be more elaborate ways to further organize the whole thing and perhaps splitting even more, but I believe this could be a good start.
That would make searching easier and alleviate these long topics a bit... Of course it's a long process and it could be done gradually.
What do you think?
