Today I went crazy at an aviation fleamarket and bought a second stage liquid fuel rocket engine of a SAM-2 (Soviet designation: S-75) anti-aircraft missile.
If I get even more crazy I might want to build a test stand and actually run it for fun.
I´m lookning for manuals, drawings and specifications for this engine, if possible in a language I understand, this means English, German, Spanish or French.
I would first need to find out which actual subtype it is and everything about maintenance, control and running it.
So far I know that it ran on a hypergolic mix of red fuming nitric acid and a kerosene type fuel.
The designation of the engine is Isayev S2.711, which existed in several subvariants.

Today at Speyer Technical Museum in Germany. You´ll recognise it from far away due to the LH Boeing 747 on stilts in it´s yard.
I also bought a WW2 RAF navigator´s bubble sextant. I´ll clean it up and get it working again.

That's crazy! A rocket engine at a flea market!
Imagine some guy has a rocket engine at home, wonders what to do with it and thinks that he could try selling it in a flea market. And than Jan comes by and actually buys that thing.

What? No improvements? What's with that gyro-stabilized M3 sleeve clamp that connects the outer two club heads with the micrometer drum? Wasn't that always a bit unreliable?
And here I was thinking you're a bona-fide engineer!
As colleague of mine had bought a jet engine of a Czech L-29 jet trainer a few months ago. He wants to build a mobile test stand and run it in his driveway in a village in the Eifel hills... . We were joking that he had the strongest leaf blower in the county.
He is a jet engine mechanic by trade.
I got hooked on space travel ever since I watched the moonlandings live as a boy.
If you are going to be in SVO, they are only a few kilometers away in the town of Khimki: ulitsa Akademika Grushina, 33, Khimki, Moskovskaya oblast', Russia
Thank you! I will try to contact them during the next few days. Yesterday I took the engine to work and after end of my shift I borrowed our boroscope and did an internal visual inspection as far as I could get into the engine. There is some corrosion on the turbine rotor and it is a bit difficult to turn, so I will have to take the turbopump apart to see what the bearings look like and to remove the corrosion with Scotchbrite.
Pictures to come.
RWessel, no, while I have a permanent girlfriend, I live mostly alone in my own place.
