Hey folks. I've done a little bit of research into model rocketry and I'm stuck with the idea of designing and projecting a rocket to put into practice all the engineering I'm learning in college - I'm into MechE. I want to start simple, doing a few tests and learning the basics - types of engines, propellants- and, after that, build something a little bit more sophisticated. I'm learning Arduino, and I want to implement things like control, guidance and data collection - acceleration, temperature, pressure - into my project. So, where should I start? I don't want to buy a ready design, I want to build my own. I know there are sugar rockets, but I don't know if this would be the best option for the project that I bear in mind. What about materials? The interior of the rocket, that comes into direct contact with the burning propellants, what should it be made of? My intent is to build an engineering project. So I want to understand the thermodynamics, do all the calculations - rocket equations and so - and theoretical stuff, in order to compare with experimental data. Any hints of how should I start to delve into this?
