  • Patent number: 8161878
    Abstract: A safety and arming unit for a fuze of a projectile has a rotor for interruption of a firing chain. The rotor can rotate from a safe position to an armed position. In order to allow the safety and arming unit to be designed to be physically compact and such that it can be assembled easily, it is proposed that it has a first and a second rotor safety device which each engage in the rotor in order to block rotor rotation to the armed position, wherein the first rotor safety device is designed to carry out a release movement by virtue of its inertia during a launch acceleration of the projectile, and the second rotor safety device has a pyrotechnic charge for producing a release movement.
    Type: Grant

  • Patent number: 7491099
    Abstract: A pressuretight contact connection for the programming and power supply for fuze electronics is described, which is provided in a housing (10) from which a contact pin (34) projects in an electrically insulated and pressuretight manner in order to make contact with a connecting element (12). The connecting element (12) has a contact surface element (16), which is provided in an insulating housing (14) and has contact fingers (24) in the area of a through-hole (18) which is formed in the insulating housing (14), which contact fingers (24) clasp the contact pin (34) in an interlocking manner when the connecting element (12) and the housing (10) of the fuze electronics are in the mated contact state.

  • Patent number: 7461596
    Abstract: A safety and arming unit (10) for a spinning projectile fuze, which has a fuze body (12) and a bearing body (14), which define a spherical cavity (16) between them, in which a spherical rotor (18) is mounted such that it can rotate, in which rotor (18) a detonator (20) 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 (18) can be surrounded by a rotor locking ring (28) in the safe position, prevents the rotor (18) from rotating through an acceleration ring (30) and a spring element (32) which connects the acceleration ring (30) to the rotor locking ring (28) in an interlocking manner, with the rotor locking ring (28) being formed with a slot (36) in order that it can be spread open by rotation and centrifugal forces into an open space (34).
