Abstract:

Some embodiments pertain to a projectile that includes a body and a support attached to the body. The projectile further includes at least one partial fin that is rotatably attached to the support such that the partial fin moves between a stowed position and a deployed position. The support moves relative to the partial fin as the partial fin moves between the stowed position and the deployed position such that the partial fin and the support form a complete fin when the partial fin is in the deployed position. The support may form a portion of the front edge of the complete fin when the partial fin is in the deployed position. The support may lock the partial fin in place when the partial fin is in the deployed position.
