Abstract:
1. A surface control assembly, comprising: a central shaft mount arranged to mount to a central shaft of a guidable projectile, the guidable projectile having a roll portion which rotates around at least a portion of the central shaft during flight of the guidable projectile to provide stabilization; a movable member arranged to control a trajectory of the guidable projectile during flight of the guidable projectile, wherein the movable member defines a flight control surface; an electromagnetic actuator interconnected between the central shaft mount and the movable member, the electromagnetic actuator being arranged to control movement of the movable member relative to the central shaft mount, wherein the electromagnetic actuator is arranged to control angular orientation of the flight control surface relative to a central axis defined by the central shaft; and a latching mechanism supported by the central shaft mount, the latching mechanism being arranged to bias the movable member to a latching position relative to the central shaft mount.
