摘要： A new fuze that reduces projectile miss-distance to a target, by correcting for discrepancies in anticipated round velocities through its flight. As a result, the fuze-equipped projectile is nominally aimed at a target and maintains improved accuracy relative to a conventional round. The fuze adjusts for the discrepancies in velocity by using an internal electric motor to mechanically actuate a drag-altering surface on the fuze body. In order to adjust for errors in the anticipated velocity, the fuze compares its preprogrammed velocity to its actual velocity at a given point in time during flight. An anticipated velocity table versus time in flight is constantly referenced so that appropriate adjustments in velocity can be made.
