摘要： 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.

摘要： A wall breaching explosive fragmentation ammunition having a tungsten alloy nose cap with ceramic cone nose which make possible penetration into a hardened target with survivability of the warhead. The ammunition employs a unitary construction with fuze completely within the projectile's shell case. The ammunition has an external plastic rotating band which also encloses an induction antenna. The antenna may signal the fuze on a wire, through a hole in the shell case. The fuze signals may be fed through a gun barrel, then picked up on the antenna. The ammunition also employs a controlled pattern fragmentation mechanism incorporating a patterned plastic liner.

摘要： A field coil stator of an electrical generator is fixed to the fuse body ofn explosive projectile within which the rotor of the generator is supported for limited rotation dampened by a pendulum to effectively induce an electrical output from the stator field coils during and after launch of the projectile from an internally rifled gun barrel. The rotor is rotationally isolated from the stator during launch by shock absorbing means to avoid defeat of the pendulum dampening action on the rotor.

摘要： A dipole magnet is placed in a sabot of an explosive projectile. The magnet is arranged and configured within the interior surface of the sabot--such that when the sabot is placed over the casing of the projectile, the majority of the magnetic flux tends to take a path through the projectile casing and between two sensing coils located within the fuze and within the projectile. The first sensing coil forms a larger circle which encompasses the aft end or outer diameter of the projectile which is made up of ferrous materials. The second sensing coil forms a smaller concentric circle (relative to the first sensing coil) and is situated inside the inner diameter of the after end of the projectile, thus encompassing no ferrous metal. The majority of the flux from the magnet enters the ferrous projectile casing, travels through the casing, and exits primarily between the two coils on a continuous path back to the magnet. In operation, as the sabot moves away from the casing after exit from the bore, the magnet also moves away. The result is that a change in the amount of flux flowing between the coils occurs. The change in flux moving between the two coils of wire creates a voltage that can be used to detect the sabot release. The second sensing coil is utilized to produce a gradiometer sensor. The output from the first and second sensing coils is provided to a summing block, the output of which is provided to a preamp/signal conditioning block. After the signal has been conditioned, the signals are provided to a differentiator and then to a threshold detector for subsequent transmission to the fuze logic.
摘要翻译：将偶极子磁铁放置在爆炸物抛射体的火焰中。磁体被布置和配置在机身的内表面内，使得当机体被放置在射弹的外壳上时，大部分磁通量趋向于穿过射弹壳体和位于内部的两个感测线圈之间的路径引信和射弹内。第一感测线圈形成一个较大的圆圈，其包围由铁质材料制成的射弹的后端或外径。第二感测线圈形成较小的同心圆（相对于第一感测线圈）并且位于射弹后端的内径内侧，因此不包含黑色金属。来自磁体的大部分磁通量进入有色金属射弹套管，穿过壳体，并且在连续的路径上主要在两个线圈之间退回回磁体。在操作中，当从膛孔出来之后，由于铠装从壳体移开，磁体也移开。结果是发生在线圈之间流过的磁通量的变化。在两根线圈之间移动的通量的变化产生了可用于检测破坏释放的电压。第二感测线圈用于产生梯度传感器。来自第一和第二感测线圈的输出被提供给求和块，其输出被提供给前置放大器/信号调节块。在对信号进行调节之后，将信号提供给微分器，然后提供给阈值检测器，以便随后传输到引信逻辑。

The safe and arm device possesses a first switch which is actuatable at the presence of a surrounding air onflow against the submunition carrier in dependence upon a submunition ejecting command; and wherein a second switch is actuatable by the first switch when the submunition-projectile has released itself from its carrier and has implemented a transition into a gliding flight phase searching for a target.

摘要： An apparatus for generating an electrical ignition current in the fuze of a projectile to be fired from a weapon, comprising an induction coil arranged in the projectile, a magnet for generating a magnetic field, a bipartite yoke, one part of which is located at the projectile and the other part at the weapon barrel, for producing a change in the magnetic flux upon passage of the projectile through the weapon barrel. According to one embodiment the part of the yoke located at the weapon barrel comprises a number of ferromagnetic rings and paramagnetic rings arranged between the ferromagnetic rings. The part of the yoke located at the projectile body comprises a substantially cylindrical body member having a substantially disc-shaped flange for the reception of the induction coil as well as a soft iron disc. With this arrangement the magnet is a permanent magnet which is disposed between this cylindrical body member and the soft iron disc. The axis of the induction coil substantially coincides with the projectile axis, and the aforesaid ferromagnetic and paramagnetic rings are arranged at the end of the weapon barrel. It is possible, according to another embodiment, to use instead of a permanent magnet, an electromagnet located at the mouth of the weapon and containing such ferromagnetic and paramagnetic rings, with the yoke at the weapon barrel being in the form of a triple-arm yoke carrying two oppositely polarized electromagnetic coils.
