Designing Model Rockets for Maximum Altitude

Click For Summary
SUMMARY

This discussion focuses on designing model rockets for maximum altitude using A or B model rocket engines. Key considerations include optimizing weight, dimensions, and the design of components such as the nose cone, body tube, and fins. The center of gravity (CG) must be positioned ahead of the center of pressure (CP) for stability. Tools like Winroc are recommended for calculating CG and CP effectively.

PREREQUISITES
  • Basic understanding of aerodynamics and physics principles
  • Familiarity with model rocket engines, specifically A and B engines
  • Knowledge of rocket design components, including fins and nose cones
  • Experience with software tools like Winroc for stability calculations
NEXT STEPS
  • Research the impact of fin shape and placement on rocket stability
  • Explore the design principles of nose cones for optimal aerodynamics
  • Learn about the regulations and guidelines from the National Association of Rocketry (NAR)
  • Investigate alternative recovery systems for model rockets beyond parachutes
USEFUL FOR

Aerospace enthusiasts, model rocket designers, and hobbyists interested in maximizing rocket performance and altitude.

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
