not sure if DIY or Sci but here we go. How do I make rocket fuel. Liquid rocket fuel. I was thinking a alcohol + Hydrogen peroxide. How do I get the pure alcohol in order for the mixture to work?

Buy ultra pure kerosene. You can use lower purity but expect more coking.

Just watch October Skys

Thanks for the timely response will do.

You will learn jack shit from October Skys. But you will be inspired. Maybe.

ok

99% pure isopropyl alcohol -- will this work?

Isp is about 1/3 less than kerosene. Better be efficient with that weight or you'll never get to orbit.

It really isn't the alcohol you should be worried about, it's the peroxide. 99% concentrated alcohol is abundantly available, but concentrated peroxide is much harder to obtain.

Why? Even clean kerosene is going to burn dirtier than alcohol, and alcohol has the added benefit of being somewhat self-oxidizing (reducing the quantity of expensive high-test peroxide needed in the fuel mixture). Kerosene is also harder to ignite.
>>7585950
Yes.

More isp. Cleaning the internals is a tradeoff for more power. Much safer since it is harder to ignite. Alcohol is a good fuel if you want to stay suborbital, but kind of pointless unless you want to bomb something.

Why would you make a rocket that doesn't go into orbit?
