Description |
This fuze has a long extension rot with the vanes at the top. The lower end is attached to the arming rod by the split pin. Immediately beneath the shoulder are the threads used to screw the fuze into the bomb. The firing mechanism consists of the detonator, creep spring, and inertia striker. This assembly is housed in a dome-shaped cavity which insures that the fuze will fire, regardless of the position in which the bomb lands. The base of the fuze is internally threaded to receive the housing of the relay element. The base of the relay housing is internally threaded to receive the long Italian booster. The relay housing is internally threaded to receive the booster in the center of the spheriacl bomb. |
Operation |
The safety pin is whitdrawn when the bomb is released. The vanes rotate in flight and withdraw the arming spindle, which is releases the steel balls. These fall into the channel and release the striker mechanism. Upon impact, the striker and the detonator overcome the creep and come together. |
