A powered projectile having a nose portion, a body portion, a tail portion, and a central axis. In various embodiments a collar is rotatably mounted to a control support portion with a plurality of aerodynamic surfaces thereon for despinning the collar. An alternator configured as an axial flux machine with a stator arranged can be axially adjacent to one or more rotors, the stator including a plurality of windings and the one or more rotors each including a plurality of permanent magnets arranged about the face of the respective one or more rotor. In various embodiments the projectile includes an assembly of projectile control circuitry. In one or more embodiments, upon relative motion of the rotor with respect to the stator, magnetic flux from the magnets interacts with the windings of the stator and passes through an air gap between the one or more rotors and stator.

The present invention relates to stackable projectiles having a warhead and a propulsion unit. An adaptor enables the warhead to be coupled to propulsion units made of different materials. Furthermore, an adaptor couples different profiles of warheads and propulsion units and allows projectiles to be stacked without need for design modifications. The assembled projectile can be fired electrically or mechanically.

Apparatus for generating energy and a method of operating the apparatus to generate energy, where the apparatus comprises a coil assembly of a pair of coils circumscribing a magnet assembly that is held in a first position until, upon an acceleration event, the magnet moves from the first position to a second position, which imparts inductive energy into the coils.

A fuze setter interface for substantially simultaneously and wirelessly transferring power and data between a fuze setter and fuze. The fuze setter interface includes separate power and communications interfaces. In the power interface, an induction coil is provided in each of the fuze setter and fuze. Power is transferred by magnetic field coupling between the induction coils. In the communications interface, a communications member is provided in each of the fuze setter and fuze, along with appropriate functions to generate alternating-current (AC) waveforms, and condition, modulate or demodulate signals. In one example, both communications members are induction coils that transfer data by magnetic field coupling. In another example, both communications members are radio-frequency (RF) transceivers that transfer data by radio signal. The RF transceiver in the fuze may be a Height of Burst (HoB) sensor. In another example, both communications members are optical transceivers that transfer data by optical signal.
