FIN DEPLOYMENT SYSTEM

摘要

A projectile having a fin deployment system disposed about its circumference. The fins are initially contained by a fin cover that is removed by aerodynamic force. The fins are then rotated around a rotational axis parallel to and offset from the central axial axis of the projectile body by the centrifugal forces created by the rotation of the projectile as the projectile passes through a barrel of a gun system or tube launcher. The fin deployment system can also have locking systems that lock the fins in the deployed position and prevent the fins from rotating back into the retracted position after deployment.

1. A fin deployment system for a projectile comprising
a plurality of fins rotatable along a rotational axis parallel to and offset from the central axial axis of a projectile body, wherein each fin is rotatable around the rotational axis between a retracted position and a deployed position; a cylindrical mount assembly defining a plurality of axial channels each aligning with the offset rotational axis of a corresponding fin; said cylindrical mount assembly defining a central opening through which the aft end of the projectile extends; and a fin cover positioned over the fins and cylindrical mount when positioned in the retracted position ,said fm cover having a tubular shape so as not to block the aft end of the projectile.
