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.
Claims5
An ignition and safety arrangement for a base-side impact fuse for a grenade projectile provided with a shaped charge insert, said fuse having:
- a housing for attaching to the projectile;
- a spin-dependent safety element and an acceleration-dependent safety element mounted in said housing for preventing arming of the fuse until the fuse has been subjected to a launch acceleration and a given centrifugal force;
- and a self-destruct device disposed in said housing for igniting the shaped charge, with said self-destruct device including a firing pin, a pyrotechnical delay segment, means for mounting said pyrotechnical delay segment in said housing for axial displacement into engagement with said firing pin in response to launch acceleration, and a booster charge for igniting the shaped charge, with said booster charge being mounted in said housing extremely off-center and being ignited by said delay segment after its delay time.
