I was at an antique shop, in St. Louis, today and spotted this cool print of a McDonnell Douglas four engine turbo prop. Obviously they never built this thing, but what would it have been called and how far along in the design process did it get? It is a neat looking plane and appears to be rather large.

Quoting mayor (Reply 1): Wonder if it could have been derived from the C-133
looks similar, but those went out of production in 61 or so and McDD didn't come together until '67. I wonder if McDD thought about reopening the line to make passenger aircraft? It looks like the nose of a DC-10 with the wings of a C133.
I did. I think it was worth $25. I paid $10 each for some TWA Boeing builders photos (727 and 747) a few years ago at the same place.
I took the picture out of the frame to see if it had any markings on the back. It is a photograph of a drawing, as it is on Kodak photo paper. It is a good print so it was done professionally. There is also a McDonnell Douglas stamp on the back that has space for date, department, and model, but all of that is blank. It has McDD's St. Louis HQ address. There is also a serial number for the picture on the back of the print: D4C 54598
The frame has a marking on it too; 8016-15-6. I doubt that means anything, but it may have been a property control number if this thing was in the offices. I have several Missile System prints from McDD (a buddy of mine was an engineer there and rescued them from the trash for me) and they have similar numbers on their frames.

There was an airliner produced in the late 1960's called the McDonnell Douglas 188. It was a stole airliner with a similar configuration to the drawing, but it was smaller. Perhaps this was an early rendition of the design, before it was down-sized? I believe one or two prototypes were produced and actually saw Eastern and American liveries for demo purposes. The design was too expensive and was scrapped.
If you go on Flickr.com, there are many photos of the type.

I guess they were pretty diversified back in the day. I had a job back in the early 1990s at a company that was using an elderly McDonnell Douglas computer system (Pick operating system) to run a call center application.
The Eastern photo is shot over St. Louis. Busch Stadium is seen in the photo and you can see the approach to the Popular Street Bridge. US40/I-64 are not there yet, but the pylons are are being built. Looks to be 1968. I have a film made in that railroad yard below, which was filmed in May of 1968 and the US 40 elevated section construction appears to be in the same state of progess as in this photo.

In the late 60's early 70's the aerospace companies were very diversified! McDonnell Douglas created a Computer Aided Design (CAD) system called McAuto. While Lockheed created the Computer Aided Design and Manufacturing (CADAM) operating system. While vastly improved over the last 40 plus years both systems are in use today.

Quoting mayor (Reply 9): Now, that looks very much like it was derived from the design of the C-133.
The C-133 was built by Douglas. We know McDonnell-Douglas built the 188. If McDD came into being in 1967 and these photos of a flying aircraft were taken in 1968 or so, that means that work on the 188 started before the merger. So was the 188 a Douglas plane or was it a McDonnell plane? Which firm originated the design? I can't imagine this thing was entirely designed and put together in the short time between the merger and the date of the photos.
That photo of the 188 next to the McDonnell hanger (STL?) is good evidence that it was a McDonnell plane, of course they may not have got around to painting the hanger yet and that plane was just visiting.
Quoting crownvic (Reply 6): Perhaps this was an early rendition of the design, before it was down-sized?
I am thinking maybe this was a proposed larger version of the 188 done after the smaller model was built. If it were an early design that eventually was downsized to the 188 the plane in the print in question would have been either McDonnell or Douglas, not McDonnell Douglas.

I thought that the MD188 looked familiar - I looked on Wikipedia and my memory was confirmed that in fact it is a licence-built Breguet 941.
Designed in France in small numbers (6 in total) it featured the four engines interconnected by a drive-shaft. so an engine failure would not mean the loss of propellor rotation and the prop slipstream would continue over the entire wing surface. This accounts for the engines being so widely spread on the wing - a so-called "Blown Wing"
It was evaluated as a STOL airliner and alsoby NASA and The US military but no orders were forthcoming.
Perhaps the print was of a design to look at an enlarged version with the "blown wing" ?

Thanks for the post. Truly a neat AC I've never seen. Love the Mock Up in Eastern Livery.

Just a thought out of left field, but could this be a potential commercial design based on their proposal for the CX-HLS program, which became known as the C-5? After all, the 747 is based on elements of Boeing's C-5 design and Lockheed did look at a passenger version of the C-5 (L-500).
From the C-5 Galaxy history page on globalsecurity.org:
All three industry designs incorporated high-wing configurations with four large turbofan engines in underwing nacelles and front and rear doors with ramps for flow-through loading and unloading. The Boeing and Douglas designs had conventional tail configurations, whereas the Lockheed design incorporated a T-tail configuration. The C-5 design submitted by Boeing was found to have superior aerodynamic cruise performance in the transonic wind-tunnel tests performed at Langley. Boeing's experience with the C-5 competition coupled with Boeing management's vision of the market-ability of jumbo civil transports (and interest from Pan American Airlines) led to the development of the Boeing 747, which enabled Boeing to dominate the world market with a new product line. Although the 747 was a completely new aircraft design (low wing, passenger-carrying civil aircraft), the general configuration influence of the earlier C-5 candidate is in evidence.
High wing, conventional tail seems to match the description. Does anyone have any images of Douglas' C-5 design in which to compare to the sketch in the thread starter? While the awarding of the C-5 contract was prior to the merger, this sketch was probably done not too long after the merger.
Looking at the design, it appears to be a widebody fuselage (you can almost image it as the DC-10), so it would definitely have to be based on something other than the C-133.

I like that theory better.
The little STOL props others are talking about was for a US competition, there were plans to build STOLports around the country so a plane was needed.
The large plane in the first post wouldn't have much to do with that, it looks to be the size of an A300 at least !
