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.

摘要： An electromagnetic turbine without moving parts includes a magnetic core with three magnetic paths and magnetic connectors arranged between the three paths forming two adjacent closed magnetic loops. Three coils extend individually around portions of each magnetic path. The three coils are electrically pulsed to provide current pulses in the coils. Driving electrical current through each of the coils in sequence results in a flow of magnetic flux external to the magnetic core. The sequence is arranged to create a continuous one-way flow of magnetic flux through the inside of the core, then out one end where the flux extends outward and sweeps external to the core to the opposite end of the core where the flux collapses into the core. The sweeping magnetic flux induces electrical currents into electrically conductive material external to and not part of the turbine. Magnetic flux from the external currents interacts with the sweeping flux, resulting in a net force. The force either absorbs energy from relative deceleration of external material, converting the deceleration to electrical energy; or electrical energy provides relative acceleration of external material, converting the electrical energy to acceleration.
