Hi!
I'm new here, and I've been studying rockets for a couple months.
I'm aware I'm probably being naive here, but I'd like to understand why
I'm under the impression that making a big (solid fuel) rocket is not so hard.
For instance, let's assume I get a 20cm diameter x 200cm length PVC tube, fill it up with rocket candy, put some cardboard around it with a nice nose cone and adjust its CG and CP with a combination of mass on the top and fins on bottom. (I guess I need to consider how the CG moves while the fuel burns.)
Then I launch it on the simplest rocket launcher I can think of (something like 3 metal bars pointing up with the rocket between then), high enough for the rocket to get aerodynamic stability (I'd need to make some calculations).
Is there something else I would need to worry about? Otherwise model-rocket-science sounds kinda "trivial" (unless you start to play with liquid fuel/multi-staging or REALLY big (and expensive, and dangerous) rockets).
