In order to improve safety, particularly during transportation and/or storage, a system (10) is proposed which at least comprises a housing (13) an explosive (3) held therein which is initiated by a blasting cap (1), wherein a sleeve insert (2, 2′) in the housing (13) makes it possible for the blasting cap (1) to be removed from the explosive (3), in that the blasting cap (1) in the sleeve insert (2, 2′) is height-adjustable, so that the position of the blasting cap (1) relative to the explosive (3) can be changed. The system (10) may include a fuse head (11) which at least comprises a primer cap and possibly a delay line (14). The blasting cap (1) may be an integral part of the fuse head (11) and insulated therewith on the base.

The present invention describes a safe-and-arm device, mechanism or assembly (160) for a projectile (100,102) equipped with a second-stage propellant (124). The second-stage propellant (124) is ignited after the projectile has been ejected out from a launcher barrel. A lockpin (190), being urged by a spring (194), is responsive to ignition of the second-stage propellant; after the lockpin (190) and spring (194) sense and respond to the second propulsion, an unbalanced rotor (164) forming part of the safe-and-arm device or assembly (160), is released to rotate from a safe state to an armed state, as the projectile continues traveling along its trajectory to a target. In one embodiment, the projectile is configured with a 40 mm cartridge containing a first propellant (122). An impact sensor may trigger an electric detonator or a point detonator may trigger a stab detonator to set off explosives disposed in the projectile.

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.
