Hello fellow people, I am planning my own rocket design since I have owned one model rocket and built my own off of the model one. My home built one flew the best out of all of them although all of them the parachutes did not deploy. I have been thinking about designing my own liquid fuel rocket so that I can reuse it and not buy the little solid rocket fuel engines by using methyl alcohol as the fuel and Potassium Nitrate, KNO3, as my oxidizer since I found out that you can it is found in high concentrations in stump remover. I few things that I am a little iffy on such as:
[*=1]How do you store and pump the fuel to the reaction chamber? Along with this I was wondering what the fuel ratio would be, I read somewhere that is was 1.2 oxidizer
[*=1]Is there any more common oxidizers or fuel that work better and are easier to find?
[*=1]Is there some common dimensions that work great, because I was thinking about 2 inches by 28 inches without nose cone which will be about 4 inches?
[*=1]Would aluminium be able to contain the reaction of the fuel?
[*=1]For the exhaust, how wide should it be in proportions to the rest of the rocket?
