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.

A shell fuse has a target acquisition sensor, such as an impact sensor, and a firing train in which a firing device carrier is movable from a safe position into an armed position. Overflight safety all the way to the target is afforded in a simple manner. There is provided a force element, in particular a pyrotechnic trigger device, which can be initiated by the response of the sensor. The force element is coupled to the firing device carrier such that the firing device carrier is movable into the armed position.

Shell fuse

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.
