A projectile includes a body, a payload within the body, a target system within the body for affecting operation of the projectile, and an inductive interface which, as part of the target system, permits transfer of at least one of power and data between the target system and an external setter system. The inductive interface includes a magnetic core comprised of a compound of ferrite material and non-ferrite material and a coil wrapped around the magnetic core.

Projectile inductive interface for the concurrent transfer of data and power

Energy ( ) and mission data ( ) for a guided projectile are transferred from a projectile setter ( ) over an inductive interface ( ). The projectile may include energy storage element ( ) to store the energy and a data storage element ( ) to store the mission data. Precision GPS clock circuitry ( ) of the projectile may receive power from a capacitive energy storage ( ) element during projectile loading until a flight battery ( ) is activated. In one embodiment, the capacitive energy storage element ( ) includes at least one super capacitor ( ) and a gun-hardened capacitor ( ). The clock circuitry ( ) may receive power from the gun-hardened capacitor ( ) if the super capacitor ( ) fails during the launching operation. The capacitive energy storage element ( ) may include one-way energy transfer elements ( ) coupled between the super capacitor ( ) and the gun-hardened capacitor ( ). A regulator ( ) may be coupled to an output of the capacitive storage element ( ) to regulate an input voltage to the clock circuitry ( ).
