Ok, reading some documentation in OR and a few books, i have seen the same term used over and over, and that is caliber. In units of measurement, that is inches, IE 50 caliber is 0.5 inches in diameter. So if my rocket has a 2.35 caliber, which according to OR basic rocket design documentation is over stable, does this mean 0.02 inches from CG to CP?
" Ensure at least 1.0 airframe caliber of separation between the (forward) center of mass and (aft) center of pressure. This is a rule of thumb, not a hard-and-fast stability solution."
what is deemed as "airframe caliber" ? is that meaning the diameter of the body tube in a measurement of caliber rather than inches? so a 3 inch diameter is a 300 caliber body tube?
I know QFactor gave me a tip of keeping the CP about 1-2 times the body diameter behind the CG.
thanks.
