NAA V/STOL Evaluation Vehicle factory model (T2-J Trainer with General Electric Lift Fan System). This Buckeye is considerably more modified than the preliminary design shown earlier in this thread: all-new, larger wing and horizontal stab, larger lift fans, new main landing gear, etc.

Ryan eventually incorporated this G.E. system into a very successful, purpose-built airframe, the XV-5A Vertifan.

To the best of my knowledge, the second image depicts a Ryan project, not an NAA one.

May be you are right Skyblazer,but hard to judge,what about co-operation between NAA
and Ryan ?.

I'd rate that as somewhere between unlikely and very unlikely (based on current knowledge).

It's much more likely that it was a matter of parallel study contracts issued by the Army to the airframers to see how to best exploit the GE lift Fan technology.

Thank you Aim9xray,


and for my dear Skyblazer,I think that aircraft was neither NAA nor Ryan,but may be it was
a Douglas design,as you mentioned before;

D-793........US Army Surveillance Aircraft Study (1960)


and may be it was a V/STOL concept.

I can't believe that there weren't any VTOL/VSTOL variants of the OV-10 Bronco proposed.  Anyone?

Not sure, that adding the "V" to an aircraft, that already has good STOL performance
is that profitable.

I have the idea that the illustrations in post 17 & 18 are General Electric concepts
illustrating the many ways their fan in the wing technology could be used...

Maybe you should check the Elytron concept on the web. The configuration of the Elytron 2S and 7S designs combines CTOL, STOL and VTOL capacity... and all the scale models so far have been promising. The 2-seat demonstrator is currently in construction, and I can't wait to see what will come of it!

No my dear Lark,


the reply # 17 was the same reply # 15 as NAA T2-J trainer,and the reply # 18 from
Flying magazine was not GE electric design,and to prove that please look to the upper
design,it was a Ryan concept not GE.

In my humble opinion Hesham , # 15 and # 17 are -not- the same aircraft.
( the wingplanform , air intakes and the undercariage are different)
The last illustration you show is indeed a Ryan Vertifan idea , one of the many...
