I’ve heard on occasion that there are some good Russian textbooks on rocketry. I’ve always been curious about them but until recently I was never able to find any. A break finally came on a comment on Amazon about Huzel a Huang mentioning an actual title Design and engineering of liquid rocket engines by GG Gahun. Even with the English title my searches came up with nothing. It wasn’t until I translated the title to Russian and searched in the Russian version of Google that I got any leads. I fond a web site offering a DJVU version of the text which I got converted to a PDF.
I can’t read it of course. I tried an online OCR (optical character recognition) software and an online translator. The combo didn’t work very well the Russian OCR had a lot of errors which significantly hampered the translator winch did an imperfect job itself. Those tool or similar ones could probably be used to create a usable English version of the text but it would take a long time for someone to go through the whole book line by line. Never the less some of the figures are informative. For example these 3 figures on how they make the corrugated regenerativly cooled nozzles. Most figures of the same thing in English texts I’ve seen are less descriptive.
I’d like to add this to the RRS online Members Library. (Even though not many will be able to read it) However I’ll hold off until some of the copyright issues are clarified. From what I understand of copyright law, depending on how we use it, we would be exempt by fair use for educational purposes. But only if we did it the right way. Plus the issue is complicated by the fact that it is an international copyright (that is if it even has a copyright on it, which I don’t know that either.) Investigating this is defiantly hampered by my having no working knowledge of the Russian language or legal systems, or international copyright. If I figure it out I’ll post an update.
The meeting was attended by 7 members. The January Launch had been canceled. The USC students had been planing a test, but that fell through, there were no other firings planed for that day.
Osvaldo relayed for Matt, our treasurer, that a Paypal account for the RRS is being worked on. They want to have a separate account for Paypal as a security measure.
Chris reported on our progress in the 501c3 nonprofit process. We’re getting free help from the USC Law school’s small business clinic where law students work with real-life clients for experience. The student helping us will be submitting out paperwork soon and we should know the results mid to late fall. Having a non-profit status at the federal level can help us with receiving donations either monetary or equipment wise since it will be tax deductible. Frank let us know that Ford was once interested in making a donation but passed since it wouldn’t be tax deductible without the 501c3 status.
Osvaldo bought up 2 things that need work at the MTA. First the tar-paper on the blockhouse is coming up and is in need of repair. Second he is interested in expanding our firefighting capability at the MTA. Currently we have pressurized water fire extinguishers, but if a fire starts where a rocket lands, which can be a long way off, and if we have to approach on foot, the fire could get out of hand by the time we get there. We discussed several ideas ranging from getting a military surplus water trailer outfitted with a water pump to be towed to the fire scene by a 4 wheel drive vehicle, to strapping a few fire extinguishers to a dune buggy or quad.
Osvaldo made the offer for use of payload space on his next rocket launch, if anyone in interested in having their equipment launched on a beta. Frank brought and gave out some surplus RRS stickers.
Osvaldo brought a book ‘Planet Mojave’ (ISBN 978-0-6154664-4-6). It’s a collection of works from the Ridge Writers, a writers club (http://www.planetmojave.com/). There are some pieces written by long time member Maryann Butterfield and one is about the RRS.
Don’t forget about checking out the new website www.RRS.org. My last post was on a neat RRS orbital launch vehicle proposal from the 40’s. My next post will be on a neat Russian text book on rocketry I’ve found.

I am making progress on my reports for the next issue of the RRS newsletter. Let me know if you have something that you would like to be in the next issue.
