Nice drawings,thank you Scrutor.
Did you ever build that model Archibald?Yeah, better option would have been its competitor, the General Dynamics 200. This one was really similar to the soviets Yak 36 /38 /41 in the sense that it had a tilting rear exhaust plus two lift jets behind its cockpit.
Despite its defaults (hot gases reingestion) this layout WORKS rather well.
I'm planing a model of the General Dynamics design using a Gripen as basis...
For more info on the GD 200A, browse the "US V/STOL projects" thread. 9 pages of oddball designs (I'm fond of the well-named NUTcrakers designs ;D)
Some things that work on a small model do scale up, others don't.I remember the excitement surrounding the bizarre looking XFV12.
Was there any way of getting it to work? Or should the engineers have realised there would not be enough lift generated?

I don't think computer modeling would have prevented the XV-12A failure. Modeling or CFD (Computational Fluid Dynamics) is based on real world observations and if nobody had ever built an augmentor lift system (or similar hardware) on the scale of the XV-12A, the software would have no basis for predicting that it wouldn't work.It’s certainly one of the last major prototype “well that didn’t work at all“ case studies, which have largely been eliminated via advanced in computer modelling etc.
