General: A further advancement in simple rocket base fuzes, this design has the wedge-shaped inertia weight to facilitate correct fuze action in cases of side-wise im-pact of the rocket. |
Description and operation: A safety or shipping clamp, covering the arming pin, also has a safety pin bradded on. When the clamp and pin are removed prior to loading the round in the launcher, this safety pin frees the set-back sleeve. On set-back, this sleeve moves back against the creep spring, and comes out of its slot in the arming pin. The arming pin is then forced out against the launcher by its spring. When the round leaves the launcher, this arming pin, which was between the striker and the detonator, is ejec-ted from the fuze by the spring. The fuze is now fully armed, the inertia weight being held only by the creep spring. On impact, the weight moves against the spring to force the striker into the detonator. In case of a side blow, the fuze will still function, because the shape of the inertia weight is such that a side blow will not cause it to bind against the fuze body, but gives it room to move side-wise and at the same time compress the spring and move the striker forward. |
