  • Fineness and Stability Margin in OpenRocket - Rocketry Forum
    I have a tall thin rocket with a fineness (aka aspect ratio or length to diameter ratio) of ~26 (80” long 3 1” diameter) As currently configured, it has a stability margin of 3 7 14 6% in OpenRocket I am trying to answer the age-old question is if this rocket is over-stable The only “rule of
  • Designing a Rocket for a (considerably) High Altitude Flight

I would love to know your opinion Thank you!
