there you find a little bit more.
Your Google skills are amazing. I spent the better part of the morning trying to find out what it was. My boss and I thank you....now I can try and get productive

Kommisar Zufall!

And Else did also research:

Yes, the article I found yesterday. And then I tried until late in the evening Romanian translation programs.

Because it gets even better, a really crazy story.

In prison Aiud (German Strasbourg) in Transylvania, there was a group of detainees, the machines produced there for the industry. You have made ​​planing machines, milling machines, horizontal and vertical boring machine, Poliermschinen, copying lathes and a hydraulic press with a pressure of 120 atm.
The warden got the group a contract to build a complete bike including engine.
Among the imprisoned engineers Commander Constantin Nicolau (former technical director of military aviation), responsible for transmission and clutch, and Sorin Tulea (aircraft engineer from Brasov), responsible for chassis, engine and electrics this bike has been developed.
The materials needed were from downed U.S. aircraft and their engines Ciyclone Wright.
And complete parts of the Cyclone engines were acquired (the cylinders and heads?) And reworked. From aluminum using a Siemens furnace, a new case has been cast and machined. The finished engine was a test run with 8000 rpm.
40 detained craftsmen and specialists involved in the project. Whether it was ever so far completed that they could have gone with it, I have not figured out.
Ing Sorin Tulea, as the only surviving witness, the bike, as it is shown in the photo, the Sighet Memorial provided.



About the displacement Unfortunately nothing is known, was certainly not a performance measure.
It may be the only copy.
Type a name or there is not.

Well done indeed! Funnily enough the heads and barrels made me think of an aero engine immediately, but you don't have gearboxes, odd manifolds and an offset output shaft on an aero engine. I did wonder if it was a single build based on one of the common two-stroke twin engines as there were a lot of strange things made in workshops back then when significant engineering skills and tools availability were more common.

I don't they took the head or barrels directly:

Technische Daten (R-1300-1)

  • Zylinder: 7, luftgekühlt
  • Bore: 155,6 mm
  • Stroke: 160,34 mm
That would give 3 l displacement..... for each cylindre!

Yes, it bears no longer bears any resemblance at all to a Cyclone head or barrel:



It's just the general design of the heads and barrels look like an aero engine - have a look at this Continental and you'll get the idea.



Old aero engines are one of my hobbies - works of engineering art.

The three engibneers are said to be from Aero Space heritage.

It reminds me of a Gnome & Rhone engine. They made a CV2 back in the 1930's that was pretty similar. They started out making aircraft engine back in WWI, I think, and were still making radials, too....

This is a different G&R engine, though. It is just too cool not to post...
