Yup, I am new to what I plan to do, but I have played with rockets (pre-fab kits) that were just 'follow the instructions' and be a moron, but your rocket will fly. I want to get away from that. I plan on rolling my own rocket engines and using homemade black powder for the propellant. I will start small and make solid core engines. Cored engines will come later. The fuel is not a problem. I just need to know the theory and ratios to make a stick stabilized engine fly. You know, take engine, attach stick, light fuse, see rocket fly type of thing. I know the center of gravity should be above the center of thrust. So for a given size and weight of engine, how long should the stick be? I assume that the density of the stick has a factor in determining its length. There has to be a 'rule of thumb' to use as a guide. Hey, this is a first step, better rockets are in the future. Let me just get the engines right first.
Please do not reply to this post with "glue part A to part B, then glue A+B to part C". What if I want to change a proven design by reducing it or making it bigger in size? Maybe I want to make a 1" rocket or make a 5' rocket. There must be something in common that applies to both sizes. Feel free to blast me if you want. I am sure that this information exists somewhere. Include a link with the reply perhaps?
