"Although this was a very novel idea for an aircraft at this time, the
concept never left the drawing board."

1/15 the loaded weight of the Osprey, some very optimistic numbers (400
MPH? Yeah, Right.), and no grasp of the difficulties in gearing and
power issues in a tilt-wing aircraft.

So you say they had "no grasp". They had built and put into naval
service in 1943 the Fletner Fl 282 Kolibri (hummingbird) intermeshing
rotor helicopter which was entirely succesfull despite the technology
of gearbox designe.
The only thing that prevented the production run of 70 extending to
1000 was allied bombing.

They had flown and tested the Focke Achgelis Fa-223 Drache which has
the same configuration in vertical flight of the V22 and P.1003.

The Nazis had a lot of Really
Cool Ideas that would have never worked (like the Sanger "America
Bomber," which would have melted quite nicely the first time they did a
reentry).

How do you know? The aircraft never re-entered at full orbital
velocity, it skipped at sub orbital velocities to reach the required
range, take opportunity of cooling effects and a lower speed of
re-entry.

The wedge shapped wing profile shows a keen understanding of
supersonic aerodynamics.

The Germans had solved the hypersonic and heat shielding re-entry
problems of the V2.

They developed SR71 A12 like chine strakes becuase their theory and
supersonic wind tunnels allowed them to:

Perhaps Eugene Sanger was a dreamer but he was heading in the correct
direction defining the problems that needed to be solved and then
solving them. He got pretty damed close and a testing program would
have refined the detail to a workable solution.

He for instance ground tested his regeneratively cooled LOX/Kerosene
engine at an Isp of 306 seconds. That's an entirely modern
performance.

A lot of the work supersonic and hypersonic that the Germans did in
the Nazi era at Penemunde fed straight into the US. Walter Dornberger
(Head of the V2 program) ended up working for Bell.

After the war, he was asked to work (along with mathematician Irene
Bredt) for the French Air Ministry, where in a bizarre plot, he was
almost kidnapped by Stalin, who recognized the value of the Amerika
Bomber.

The US could do with a few more Nazi Era engineers. Apart from Bono
and Hudson things have been **** with the US space program since they
retired.
