A strange Model to Lockheed C-5

[hesham]

Hi,


here is from NASA,a wind tunnel Model to Lockheed C-5,but the two engines in each wing are mounted
very close,is that belong to C-5 or not ?.

Those flaps look way larger than I'd expect on the C-5, the trailing edge looks to be almost level with the main gear sponsons. Maybe a STOL concept, using the flaps to deflect thrust?

May be you are right Hobbes.

Maybe the other photos of that series can give a clue, especially
"4590541798_f13bc61554_o.jpg".
And for all photos it is said :NASA : STOL. So I would second Hobbes, that it
is a STOL design, although the conclusion, that it was a design for a STOL version
of the C-5 could be far fetched. Wind tunnel models sometimes were used for testing
concepts, that principally had nothing to do with the original model.

these are variations studied under NASA Langley Externally Blown Flaps (EBF) program using [handy] modified C-5 model as a basis

NASA used C-5 models as generic transport shapes for a variety of STOL and VSTOL studies, these were not actual "projects", only experiments. We've mentioned them before too! Anyway, this doesn't belong in the "Postwar Aircraft Projects" section.
