    Abstract: A propellant device of consisting of a compact charge and a firing system for pipe weapons or ballistic drives is proposed. At least one electromagnetic radiation absorbing medium, e.g. carbon black, is dispersed in the compact charge and can be activated by means of a firing system emitting electromagnetic radiation. The compact charge is thereby disintergrated in fragments through triggering of the firing system and the fragments are accelerated into the gas volume produced during burning of the compact charge. The inventive propellant device avoids the use of chemical firing as well as mechanical firing means. Moreover, fragmentation of the compact charge permits maintenance of the produced maximum pressure over a longer period of time to impart a higher muzzle velocity to an object to be accelerated, e.g. a projectile, a rocket or the like.

  • Patent number: 6584906
    Abstract: The invention relates to a method and a device for triggering a warhead in a target-tracking guided missile. The guided missile has an impact fuse and a proximity fuse for triggering detonation of the warhead. The invention triggers the warhead such that the damage caused to the target, such as an enemy fighter aircraft, becomes maximal. To this end, the miss disdance is predicted from influencing variabled detected during the flight of the guided missile. The warhead triggering delay time of the proximity fuse is set dependent on the predicted miss distance to achieve such maximum damage.

  • Patent number: 6504601
    Abstract: A laser radar-proximity fuse with a laser-range measuring device and mask or camouflage discrimination, wherein for the initiation of the fuse, is no longer triggered at the beginning rather but at the end of an echo pulse configuration, even though its comparatively flat descending or falling pulse flank is or is not adapted for the determination of a clear, reproducible or controllable triggering point-in-time. By applying a Constant-Fraction-Trigger-Principle, which has heretofore been applied primarily to the rising or ascending flank of a pulse, there can be also derived a good controllable range or distance-dependent triggering pulse for the thereby optimized initiation of the fuse from the flatter rear flank of the echo pulse configuration, whereby the attacking of the target will not take place prematurely, but will be better directed toward the target center.

  • Patent number: 6480140
    Abstract: The present invention is to a method and system for providing protection from an EMS-targeted weapon by providing an appropriate spoofed EMS signal to cause an EMS-targeted weapon to determine an apparent object distance sufficiently close to the EMS-based targeting threat to nullify the weapon. In a first embodiment, the EMS-based targeting threat uses reflected EMS emissions, such as RADAR, to target the object the apparent object distance nullifies the weapon by falling within a weapon-safety lockout distance determined by a fire control system of the targeting threat. In another embodiment, the EMS-based targeting threat uses EMS signals from an external source, such as GPS, to target a position of the object and the apparent object distance nullifies the weapon by causing premature detonation at a safe standoff distance from said object.

  • Patent number: 6460460
    Abstract: A laser activated grenade is provided which includes a controllable laser source activated at specific times to generate radiation pulses. An energetic material within the grenade is ignited upon delivery of the generated radiation pulses. A propellant charge material triggers a propellant explosive train when the energetic material ignites. The grenade further includes load materials which are selectively activated once the propellant explosive train has been launched. The laser source may be located remotely from the grenade in order that the generated radiation pulses travel to the grenade through a fiber optic cable. Alternatively, the laser source may be embedded in the grenade and activated by a microwave/RF coded signal received from a remote signal transmitter.

  • Patent number: 6389974
    Abstract: A passive proximity fuze. The inventive fuze (10) is adapted to be mounted on a munition (11) and includes a receiver (16) adapted to lock on to a signal transmitted by a target transmitter (12). The receiver (16) detects a Doppler shift in the signal as the munition approaches the target. When a closest point of approach is reached the Doppler shift changes from increasing to decreasing. The inventive fuze (10) includes a mechanism for detecting this change in the Doppler shift and provides a detonation signal in response thereto. In the illustrative embodiment, the receiver (16) is an FM receiver. The mechanism for detecting a change in the Doppler shift may be implemented with discrete analog circuitry or digital circuitry. In an illustrative analog implementation, first and second resistive/capacitive networks (R1C1 and R2C2) are employed to compute a second derivative of the Doppler shift signal output by the receiver (16).
