A safety and arming unit for a fuse includes a firing chain having first and second firing devices defining an intermediate space therebetween and a barrier blocking the intermediate space in a safe position. The firing chain is brought into an armed position by a releasing movement vacating the intermediate space. First and second mutually independent securing devices lock the barrier in the safe position and execute an unlocking action based on two mutually independent physical arming parameters. A compact and very reliable safety and arming unit can be achieved in this way.

Safety and arming unit for a fuse

An activatable battery for an electronic artillery fuse and mortar fuse includes an ampoule filled with an electrolyte, and an activation device for rupturing the ampoule. In order to evaluate the duration of a mechanical impulse acting on the battery, the activation device can be freed by a timing member having an inertia body which is axially and rotatably displaceable and against which a compression spring is operative. A compact structure and reliable installation of the ampoule in the battery is achieved in that the battery has an upper battery portion and a lower battery portion, the activation device is provided in the upper battery portion and the ampoule is disposed immovably in the lower battery portion.

Activatable battery for an electronic artillery fuse

A method and an arrangement for the detection of a coil in an electronic circuit, which is operated with a direct voltage lying within a prescribed voltage range, and in which the coil together with a condenser forms an electrical oscillating circuit.

Method and arrangement for the detection of a coil

A safety and arming unit with a safe separation distance device (), which acts as a function of a free-flight incident flow and temperature, for the fuze () of a projectile (), which fuze is hermetically sealed from environmental influences, has, as a measurement device for the cooling, as a function of the incident flow, of a conductor through which current passes, in the heating circuit () of a resistant heating element () which is fitted flat on the fuze casing surface (), an electronic current measurement apparatus () which is connected upstream of an evaluation circuit (), in order to ram a firing circuit. Two heating elements (&#x2033;), which are fed in the same way, are preferably arranged one behind the other in the incident flow direction (), and, additionally as an environmental temperature sensor, a comparison heating element (') which is not influenced by the incident flow (). This results in a reliable safe separation distance, even for slow projectiles (), without adversely affecting their aerodynamic behaviour and independently of the environmental atmosphere.

Safety and arming unit for the fuze of a projectile

A penetration-capable projectile has a casing and a fuze with a fuze housing lower part. An interface area between the casing of the projectile and the fuze housing lower part is formed with a shape and/or strength modification which prevents the fuze housing lower part from being pushed into the casing on impact with a target that is to be penetrated.

Projectile with a penetration capability

A safety and arming unit () which is designed in particular for an electrical fuze circuit () does not reliably respond just to lateral loads on one side, but responds only to centrifugal forces produced by the spin during free flight, in that two contact pairs (--) which are connected electrically in parallel with one another via rings () and are arranged diametrically opposite one another on a cross-sectional plane of the fuze () are both no longer electrically conductively bridged at the same time by the bolt () because, just by virtue of the centrifugal force, both bolts () are simultaneously moved radially outwards from their short-circuit safety positions in their blind holes (), which are oriented transversely with respect to the rotation axis ().

Safety and arming unit for a spinning projectile fuze

A pressuretight contact connection for the programming and power supply for fuze electronics is described, which is provided in a housing () from which a contact pin () projects in an electrically insulated and pressuretight manner in order to make contact with a connecting element (). The connecting element () has a contact surface element (), which is provided in an insulating housing () and has contact fingers () in the area of a through-hole () which is formed in the insulating housing (), which contact fingers () clasp the contact pin () in an interlocking manner when the connecting element () and the housing () of the fuze electronics are in the mated contact state.

Pressuretight contact connection for fuze electronics

A safety and arming unit () for a spinning projectile fuze, which has a fuze body () and a bearing body (), which define a spherical cavity () between them, in which a spherical rotor () is mounted such that it can rotate, in which rotor () a detonator () is provided. In order to make the safety and arming unit suitable for fuzes in weapon systems with extremely fast munition feed units, the rotor () can be surrounded by a rotor locking ring () in the safe position, prevents the rotor () from rotating through an acceleration ring () and a spring element () which connects the acceleration ring () to the rotor locking ring () in an interlocking manner, with the rotor locking ring () being formed with a slot () in order that it can be spread open by rotation and centrifugal forces into an open space ().

As activatable battery for an electronic artillery fuse includes an ampoule filled with an electrolyte, and an activation device for rupturing the ampoule in response to the application of an impulse of predetermined minimum magnitude. The activation device includes a timing mechanism for increasing the duration for which the impulse must be applied in order to enable the rupturing to occur, thereby increasing the safety of the fuse.
