Stability factors are advantageous for projectile designers, as they allow a good estimate of ballistic stability without having to analyse a large flight envelope with numerical analysis, which can be time consuming and resource intensive.
WebApr 9, 2024 · Quick Reference. The resistance of a rotating body to a change in its plane of rotation. The faster a body spins (the greater its angular velocity), the greater the stability of the body in its particular position or orientation. Gyroscopic stability accounts for the stability of a spinning discus or a spinning football in American football. WebJan 14, 2024 · Likewise the stability calculation method could be something as simple as McGyro or something more reliable like accurately computed (or measured) moments of intertia, etc. in the fundamental gyroscope stability formula. Or it could be a reliable interpolation based on measured Sg values from something like the BRL spark range.
