Abstract
A deployment device for stabilizing fins of a projectile includes at least one pallet and a holding device for each fin. The pallet is oriented to receive an aerodynamic flow when the projectile is fired and thus transfers a resultant strain to the fin to deploy it away from the projectile. The deployment device can be used for fins of a projectile fired from smooth barrelled weapons.

A deployment device for deploying at least one foldable stabilizing fin of a projectile that moves from a folded position to an unfolded position as the projectile moves in a projection direction, said deployment device comprising at least one rigid pallet disposed adjacent a periphery of the projectile and means attached thereto for contacting and releasably holding the at least one rigid pallet to a forwardmost end with respect to the projection direction of at least one folded fin until said at least one rigid pallet receives an aerodynamic flow when the projectile is fired, to thereby move the at least one fin from the folded position to the unfolded position.
A deployment device for deploying at least one foldable stabilizing fin of a projectile that moves from a folded position to an unfolded position as the projectile moves in a projection direction, said deployment device comprising at least one rigid pallet disposed adjacent a periphery of the projectile and a holding device cooperable with and attached to the pallet, said holding device contacting and releasably holding said at least one rigid pallet to a forwardmost end with respect to the projection direction of at least one folded fin until the at least one rigid pallet receives an aerodynamic flow when the projectile is fired, to thereby move the at least one fin from the folded position to the unfolded position.
A method for deploying at least one foldable stabilizing fin of a projectile from a folded position to an unfolded position as the projectile moves in a projection direction, said method comprising:
- releasably connecting the forwardmost end with respect to the projection direction of the at least one fin when in the folded position to at least one rigid pallet that is adjacent to a periphery of said projectile;
- and
- positioning a surface of the at least one rigid pallet such that said at least one rigid pallet receives an aerodynamic flow when the projectile is fired, to thereby move the at least one stabilizing fin from the folded position to the unfolded position.
