    Rocket design in this century :)

    Is there any formulas for wing area vs rocket length? I what to build a customer rocket. I know I have to have the center of gravity higher than the center of pressure. If the fins are too small, not enough pressure (CP too high), weight distribution wrong, then may need to put clay in cone. I'm...

    Tips and Guidelines for Aerodynamic Stability?

    I've been designing a simple one stage rocket with OpenRocket, which allows the user to design and simulate their designs. I was always told that a general rule of thumb for a rockets stability is that the center of gravity should be 1-2 calibers above the center of pressure. With this rule...
