Abstract
Some embodiments pertain to a projectile that includes a casing and at least one fin that extends from the casing. The projectile further includes a drive inside the casing and an adjustment mechanism inside the casing. The adjustment mechanism includes a first gear that engages the drive and a second gear that engages the fin and the first gear. The second gear includes teeth that are different distances from an axis of rotation of the second gear. The teeth of the second gear that engage the first gear may be the farthest from the axis of rotation of the second gear when the fin is aligned with a flight axis of the projectile. The engaging teeth of the second gear get closer to the axis of rotation of the second gear as the fin is maneuvered away from the flight axis of the projectile.
