Model Rocket Design

  1. Hello,
    This summer I would be interested in designing my own model rocket. I do not have a lot of aerospace/aerodynamics (read the NASA (http://www.grc.nasa.gov/WWW/k-12/airplane/)) knowledge but I do have a good grasp of math and physics.
    I would like to use a A or B model rocket engine and get then maximum altitude out of the rocket. In the end maybe try to beat the record but for now just want to get started with a design and learning how this works.
    So how would I start?

    I got a list of questions(list of how to start) that I will research and try to answer
    Am I missing any important things?

    -best weight and dimensions

    nose cone(size, shape)
    body tube(size, shape)
    fins(size, shape, locationg on body tube, number)
    *idea* with the right spin would having curved fins help?
    centering tube(distance out of the body tube)
    center of gravity(position)
    center of pressure(position)
    ***CP is behind the CG***

    should the rocket have transition from thin at top to thick at the bottom?

    Also would this be allowed at a competition?
    rocket with no parachute?
    push rocket with ejection charge and eject engine out?(my own idea, not sure if it would help a lot)
    Thank You

  3. Hi,
    Well first if you want more advice go to tripoli (Internatinal amateur rocket group):
    http://www.tripoli.org

    I suppose your in USA so you should watch the NAR site :
    http://www.nar.org

    The best weight would be 0.000000001 pound :)

    An a quick and easy way to calculate the CG-CP is Winroc:
