besides, when it comes to women and shoes, you should know the answer is never going to be simple... right, precocious? ;)
When I did a random page down of the thread it looked like they were all favorite questions. :o
If that's the case "I would like to know why Russian rocket engines use 4 nozzles and American ones just one. What advantages and disadvantages are there? What other differences are there between American and Russian rocket engines? (turbopump, combustion chamber,... )"
;)
I think these are suppose to be more personal questions so we can get to know each other better but OK here's the answer:
"There are many reasons dealing with shear size, complexity, and cost. Example: A single US F-1 engine from the Saturn V moon rocket, with one very large nozzle directing 1.5 million pounds of thrust, was a very complex and costly nozzle design to build. The fabrication tooling and vacuum braze chambers needed for it were tremendously large and costly. On the other hand, the Russian RD-170 engine, with 4 smaller thrust chambers directing a total of 1.9 million pounds of thrust, was able to take advantage of a thrust chamber technology that had already been proven using very similar sized tooling and similar fabrication methods used for other Russian engines. It's basically a tradeoff. The single thrust chamber engine has fewer parts and is theoretically more reliable, but more costly and complex to build. The multiple thrust chamber engine has more parts and a theoretically higher probability for more things to fail, but is much less costly and complex to build."
I don't even know what that means
