Physics Stack Exchange is a question and answer site for active researchers, academics and students of physics. It's 100% free, no registration required.

Does anyones know which materials (or type of steel) are used to make rocket engines nozzles & combustion chambers?

What are the tricks to reduce temperature of the engine except trying to cool it with fuel/oxidant?

Are there any good books around on rocket engines design?

bah, we don't stoop to the likes of rocket science on this site ;-) But seriously, I wonder if this is more of an engineering question? –  David Z Aug 5 '11 at 4:33
    
Maybe engineering too, but I guess there is no other stack-exchange site for that? –  BarsMonster Aug 5 '11 at 6:02
    
It doesn't matter whether there's another SE site for engineering, the issue is whether this question is about physics or not. And the more I think about it, the more it seems like this is not about physics, it's about practical rocket construction, i.e. engineering (although one certainly can ask good physics questions about rocketry, and even about the thermodynamics of the engine). –  David Z Aug 5 '11 at 7:59
