Convair "Super Jet Transport" from 1959.
These pictures are in this large thread somewhere, so I'll just post the link at the SDASM Archives.

From FlightGlobal.com, this cutaway drawing is described as "Douglas SST"

 

[blackkite]

Hi! Enjoy.

 

[Skybolt]

Circle, that's a notorious error in the Flightglobal archives. In reality it is the Lockheed L-2000 Phase 2B. http://www.flightglobal.com/pdfarchive/view/1966/1966%20-%200145.html, preceding and following pages.
Douglas had some private venture developments, notably Model 2229 in 1960-1961, but by 1963 they were on the back burner and not pursued seriously. Girigory (Flateric) some time ago uncovered a Douglas Fortune Magazine advertisment depicting a couple of SST (actually three, one plus two alternate config of a second, VG and not VG) different from the known 229 and apparently mid-60s, but AFAIK nobody knows more about them. BTW, Grigory, do you the know the date of that issue (or an hgher rez scan of the AD ?)

Skybolt, thank you for confirming that. I thought it looked like a stubby Lockheed L-2000, but did not want to call these good people liars.

The only serious Douglas SST project I'm aware of is based on the XB-70: a pure delta with fold-down wingtips and engines grouped in a center-fuselage housing. In fact, I believe North American Aviation either participated in its design or shared a lot of data with Douglas. See attached photo of 1/10 scale Douglas SST factory cutaway. Is that the Douglas Model 2229 you are referring to?

 

[Stargazer]

I believe so. Please find attached the Nov 30, 1961 Flight International article for the Douglas Model 2229.

Not liars, just... wrong.

 

[Skybolt]

Real, I'd guess, probably some concepts put down during the company evaluation to participate or not to the FAA 1963 competition. The performance mentioned in the title were those asked for in the first round of RFP. Douglas ended up not entering. Another company who thinkered and then decided against was Rpublic, which did some concept studies.

The Douglas ad has resufaced recently on eBay:

.
As for the Model 2229, I don't see any direct derivation form the XB-70, if not in a very general way. Probably it derived from the work done by Douglas under the Study Requirement 169 from 1958.

My recollection came from a book (The SST: Here it comes, ready or not). This loose connection between the Douglas 2229 and the XB-70 was recently discussed in replies 372 and 373 of this thread. I should have checked...

I've read and re-read all 27 pages of this thread, and searched the forum, but as far as I can see, the following has not been posted up here:

A 98 page long Boeing report on the Boeing 2707-300 SST, as at September 1969.

If this has already been posted up here on SPF, please accept my apologies in advance.

Well, if you'd searched for the URL you'd have found it...

In 1961, NASA tested the scale model of a variable sweep supersonic transport derived from a sweep-wing fighter design tested the previous year:

Derived from B-70...

 

[Skybolt]

mmm, during the 1964-65 New York World Fair TWA had a suite in the Transportation Pavillion with a big mural illustrating an SST concept taking off (as seen from an air terminal window). Only very low res and small pictures of the suite exist, with the SST mural in the back. Maybe this has some relation.

 

[Triton]

The date stamp on the painting is "Dec 24, 1963."

Do we have these? Since its file sharing blog, the original source is unknown to me.

From the style of the blueprints I said for myself, that I wont be surprised, if the Scott is somehow related. Well, I am not surprised

Since its file sharing blog...

"File sharing blog?" Does it "share" more than this "teaser" image, or does it have the full-resolution drawings?

 

[Matej]

Only this teaser image as the illustration for short SST entry. I made the attempt to find the blog once again, but its not easy. I spent today almost 7 hours with Google looking for a lot of things. You can be sure that when I find someone who share your commercial drawings, I will give you the aviso
