    摘要: An onboard sensor suite generally includes two main components: a proximity sensor suite for measuring the projectile muzzle velocity; and a pressure sensor suite for measuring the projectile airspeed. The flight velocity of the projectile can then be estimated with a high degree of accuracy using either the muzzle velocity by itself or the airspeed by itself, or, in a preferred embodiment, by using both the muzzle velocity and the airspeed. The proximity sensor suite includes proximity sensors that are mounted along a projectile body; a wire harness; and an onboard computer or CPU. The pressure sensor suite includes a Pitot pressure transducer and two static pressure transducers that are mounted within the projectile body; a wire harness; and a CPU.

    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.
