ABSTRACT:
An ignition and safety device for a grenade projectile provided with a shaped charge insert and having a bottom-side impact fuse that has a spin-dependent safety element and acceleration-dependent safety element (14, 17), and a self-destruct device. The self-destruct device includes a pyrotechnical delay segment (29) that is axially displaceable into engagement with a firing pin (30) by means of the launch acceleration and acts on a booster charge (8), which is disposed extremely off-center of the projectile axis for the projectile effective charge. Consequently, no shaped charge jet is formed during self-destruction for the projectile.
