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 ().

Safety and arming unit for a spinning projectile fuze

A safety and arming device () for a spinning projectile fuze, which has a fuze housing (), which is in the form of a pot, and a bearing body () with a booster charge (). A spherical rotor () with a detonator () is mounted between the fuze housing () and the bearing body (). A radial groove () is formed in the fuze housing (), and an annular groove () is formed in the rotor (). A holding ring () is forced against the annular groove (), which is axially offset with respect to the radial groove (), when the safety and arming device () is in the safe position. The holding ring () is designed with a separating slot () and a further, shorter slot (). The separating slot () and the further slot () extend at the same distance apart in the circumferential direction of the holding ring () and define annular segment jaws (). The spring device () has a pair of cup springs (), which jointly form a horizontal V-shaped spring profile.

Safety and arming device for a spinning projectile fuze

A projectile fuse includes a carrier for an igniter. The carrier is held in a safety position by a safety element, which under the effect of centrifugal force moves to release the carrier. The safety element comprises a piston guided in a bore formed in the fuse body. The bore is filled with a flowable medium. The piston is provided with an orifice for enabling the medium to flow from one end of the piston to the other under the effect of the centrifugal force. The medium thus brakes the movement of the piston and creates a time delay before the carrier is released.
