摘要： A stabilization system for a projectile includes both fixed fins which exd outwardly from a core and folding fins. Each fixed fin has a pocket wherein a folding fin is pivotably supported. Each folding fin is in the folded state while the projectile is in the bore of the gun from which the projectile is to be fired and the fin unfolds after exiting the bore of the gun. Once the gun is fired to propel the projectile, the folding fins are retained in the folded state due to a moment which is a function of acceleration setback. Shortly after the projectile exits the bore, when the gas velocity Vg exceeds the projectile velocity Vp a moment, due to a pressure difference in the pocket and outside the pocket, is applied to each folding fin to urge it to its unfolded state.
