Various Vought VTOL/VSTOL/STOL projects

Interesting comparison, but there are notable differences. The trailing edge behind the engine exhausts is diamond-shaped on the RCS model, not on the LOAF-11. Also the fins are much closer at the tips, and the wings are not pointed.

The bottom pic is supposed to be XST but I have never seen any other angles of this pole model.

Great find Thiel and Sublight.

The book I got it from is an absolute goldmine. Aside from the XC-142A, which it covers in extreme detail all the way down to cockpit layout, it also has drawings and pictures of a number of VSTOL and SSTOL aircraft that I've never run across anywhere else.

You can thank Stargazer, he sniffed them out.

Actually what I did "sniff out" was the set of Rutan designs for SOFTA. And sublight dug them out. So it really was team work. Wish this could happen more often! I'm telling you, if I was over in the U.S., there is a wealth of archives I would gladly go dig into...

From the 1981 LOAVES study linked above...

Either I'm crazy, or they built an RCS model from the LOAVES study.....

The well circulated Senior Citizen design with the delta wing and the two strips of vertical lift engines, could be a misinterpretation of LOAVES-11. The numbering of the squares kind of struck me as odd though, almost like they were small vertical cells to hold something, say a standing or seated human. Which would dovetail into SOFTA and the SpecOps team insertion mission (minus land vehicle requirement for Senior Citizen), and wouldn't be all that different in terms of human stuffing layout from the SOFTA design that used the plenum (the first one)
 
A fascinating and as-yet unseen here (I think) VTOL project from Vought, found in TsAGI's Tekhnicheskaya Informatsiya No.17-18, 1980:

And from the same publication, same issue, a jet VTOL using the same basic configuration:

Judging the shape of the engine nacelles, the jet version would have been a four-poster.
The turboprop version would have had tiltable nacelles and lift engines under those
doors in the tail and behind the cockpit ?
 
I found a chronology of Vought V/STOL Concepts from April 1978 that might be of interest to this discussion.

The twin canard looks interesting, especially with thrust more proportionate to center of gravity. Glad they kept to Harrier, though, because they all look progressively too complex.

A few more of what I have on the VTOL side of Vought - should have paid attention and place the HSV designs elsewhere.

Enjoy the Day!

Is there any more information for Case #6 in the first image? Or a 3 view of the aircraft in the second?
