ADO-12 to "US-FRG" AVS V/STOL Fighter Programs

[uk 75]

The US certainly devoted a lot of time and effort to VSTOL from the 50s on.
I think they came to the sensible conclusion and left it to the Marine Corps.

Could you explain the source a bit better? Was it found online?

boxkite visited in person in 2001. He has a bunch of material from this visit, but the archive isn't amenable to return visits.

VSTOL is just really, really inefficient and doesn't make much sense with our current level of tech. Brits did it about as well as it could be done with the Harrier model of a central engine with rotating nozzles that doesn't penalize you with lots of extra weight. The Russian/US approach suffers from those extra vertical engines behind the cockpit that become useless weight in flight and takes up space that's needed for fuel. And even the Harrier/Pegasus model still suffers the range issue. Out in the fleet, US Navy pilots would joke that Marine Harrier drivers would be in Bingo Fuel as soon as they'd finished taking off.

In another thread (in the Designations section) boxkite mentioned a 2001 visit to the EADS archive. And it sounds as though the resident archivist is none to keen on visitors ... perhaps explaining why this archive has no website?

For those in the Munich area looking for an outing, maybe just bang on the door and demand to see Herr Mühlbauer?

...

Oh no, stop! Mr. Mühlbauer was a great help to us! It wasn't his fault that we weren't allowed to see or even copy everything. Our first (and only) visit was to gather material for presentations on vertical take-off projects from all over the world. If we had not limited ourselves to this, he would certainly have provided other documents in advance. It was around this time that his superiors decided that he should no longer be a permanently employed archivist at EADS, but should become self-employed in order to serve his previous employer in this way - EADS thus avoided insurance obligations and the like. Visitors from outside did not bring the company any money, it cost them money, because Mr. Mühlbauer would have had to look after us.
As I said, the decision-makers had other things in mind than pleasing a few 'project collectors' .
If he is reading this, I would like to thank Wolfgang M. once again for the help he gave us on this one day. Not forgetting the interesting articles he published in the magazine FLUGZEUG CLASSIC - I only have to mention the EK-33 ground attack aircraft project.

A guy is currently selling the once "Secret" Final Report Volume I on the ADO-12 Phase 1 program.
At $750 it is unlikely that any of us can afford it, but at least I've saved all 16 images in their largest version for the forum:

$750 is in the ballpark of a group buy, potentially, if enough people are willing to chip in.

Thanks very much for sharing your find Stargazer

An attractive and sleek design, none the less.
Love the landing gear.

Is there an actual artist impression of this given drawing within this thread?

Somebody bought it. Safe bet likely the same moneybags who bought the AP-77 volume.

That seller is gonna be *insufferable* from here on...

He offered the XF-103 document for $1200 to everyone watching it. $200 off I think?

No. It has some family resemblance to other Republic VSTOL projects though.

Basically ADO-12 design is largely the early US/FRG design with a weapons bay and the lift engines mounted conventionally in the fuselage instead of popping out.

Thank you for the clarification Paul.

Comment This design resembles the one referenced in the novel "Shadow 81" by the writer Lucien Nahum, where using a new fighter stolen by its pilot during a mission in Vietnam, he uses it with his accomplice to intercept and threaten to shoot down a passenger plane...!

Vintage Wooden Swing Wing Fighter Jet ModelI have not been able to identify this model, but my best guess is that is a 1960s vintage V/STOL prototype, or a variant of the West German AVS described in
