Small smart weapon and weapon system employing the same
A weapon and weapon system, and methods of manufacturing and operating the same. In one embodiment, the weapon includes a warhead including destructive elements and a guidance section with a seeker configured to guide the weapon to a target. The seeker includes a detector configured to receive a distorted signal impinging on an objective lens from the target, memory configured to store target criteria and a correction map, and a processor configured to provide a correction signal based on the distorted signal, the target criteria and the correction map to guide the weapon to the target.
Firing switch and method of operation
The present invention concerns a firing switch for a downhole ballistics device. More particularly, but not exclusively, this invention concerns a firing switch for a downhole ballistics device and a method of operating the firing switch. The invention also concerns various safety features relating to the firing switch. A firing switch arrangement for a downhole perforating gun (26, 28, 30, 32, 34) is provided, and comprises a firing switch (26, 28, 30, 32, 34), and a detonator (40), the detonator arranged to be activated in response to an electrical signal from the firing switch. A removable safety tab (42) is associated with the detonator, the removable safety tab arranged to provide a short circuit to the detonator, such that the short circuit is removed if the removable safety tab is removed.
SAFETY AND ARMING DEVICE FOR AN INSTANT IMPACT POINT FUSE AND FUSE INCLUDING SUCH A DEVICE
A safety and arming device for an instant impact point fuse for a gyratory projectile and a fuse equipped with such a device. The device includes a rotor carrying a primer held in a safe, non-aligned position with respect to a striker by a sleeve pressed against a flat spot of the rotor. The device also includes a flyweight that, when subjected to the longitudinal acceleration resulting from the shot, exerts a pushing force on a first end of at least one lever, the second end of the at least one lever being located below a collar of the sleeve. The pushing force of the flyweight causes the lever(s) to pivot about a pivot point, the pivoting of the lever then separates the sleeve from the flat spot of the rotor permanently, releasing the rotor.
Dual safety fuze for grenade
A hand grenade fuze includes a secondary safety feature in the form of a trigger pin inserted through the striker lever. One end of the trigger pin has an undercut portion. A slide bar is disposed in the fuze body and has a keyhole opening at one end for selectively engaging the undercut portion of the trigger pin. A trigger has one end connected to the slide bar and another end rotatably fixed to the fuze body. A spring biases the trigger away from the fuze body. When the trigger is depressed, the slide bar translates and releases the trigger pin, which releases the restraint on the striker lever.
SMALL SMART WEAPON AND WEAPON SYSTEM EMPLOYING THE SAME
A weapon and weapon system, and methods of manufacturing and operating the same. In one embodiment, the weapon includes a warhead including destructive elements and a guidance section with a seeker configured to guide the weapon to a target. The seeker includes a detector configured to receive a distorted signal impinging on an objective lens from the target, memory configured to store target criteria and a correction map, and a processor configured to provide a correction signal based on the distorted signal, the target criteria and the correction map to guide the weapon to the target.
Safe and arm mechanisms and methods for explosive devices
A SAFE and ARM mechanism includes an elongated casing having a first end and a second end. A high-G force firing pin is arranged relatively near to the first end and a low-G force firing pin is arranged relatively near to the second end. A detonator is arranged between the high-G force firing pin and the first end. When a G-force within a first range of magnitudes is applied to the casing along its longitudinal axis, the low-G force firing pin is displaced to strike a portion of the high-G force firing pin, and if a G-force within a second range of magnitudes is applied to the casing along its longitudinal axis, the high-G force firing pin is displaced to strike the detonator. The device may become ARMED in response to a centrifugal force generated by spinning the casing on its longitudinal axis.
SAFETY DEVICE FOR AN IGNTTER. USE OF THE SAFETY DEVICE AND METHOD OF ACTTVATTNG AN IGNTTER WITIT TIITS SAFETY DEVIC E
The invention relates to a safety device (1) for an igniter (2) comprising an ignition element (3), a rotation element (4) comprising a detonator charge (5), an axial safety (6) and a rotation safety (7), wherein the rotation element (4) can be held in a specific, first rotation element position (4.1) by means of the axial safety (6), wherein the rotation element can also be held in the specific, first rotation element position (4.1) by means of the rotation safety (7), wherein a wall (8) of the rotation element (4) protects the detonator charge (5) in the specific, first rotation element position (4.1), front ignition by the ignition element (3).
