A testbed concept. The J34 turbojet would have been replaced by a J85-GE-5 driving two lift fans.North American proposed a VTOL versoin of the good old T-2 Buckeye
(from Flying Review 1965)
It has a puffer jet with vanes on a short, tail-mounted extension, using bleed gases from the turbines.robunos said:It's hard to tell from the 3-view, but does this have a tail-mounted fan for pitch control?
circle-5 said: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.

Jemiba said:Not sure, that adding the "V" to an aircraft, that alrteady has good STOL performance
is that profitable.
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!Jemiba said:Not sure, that adding the "V" to an aircraft, that already has good STOL performance

lark said: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...
lark said: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...
lark said:I'm not convinced.
Besides , in the captions with the artist impressions in the mag.article there are
no manufacturers names nor designations exept General Electric.
Otherwise the photo's give more info...
