IMPACT FUSE (MODIFICATIONS) Russian patent published in 2005 - IPC

FIELD: impact-action fuses applicable in ammunition both of rifle and smoothbore guns.

SUBSTANCE: the impact fuse has a body, bushing with a cocking mechanism, sector-like slide rotating in the plane of the fuse axial section, striker with a safety spring and inertia body compressed in the service position to the bushing through the body for motion of the inertia body at an impact of the ammunition at an obstacle. The sector-like shape of the slide and location of the slide cocking spring in parallel with the fuse axis make it possible to minimize the fuse diametrical dimension. The fuse slide is blocked against an unauthorized turning by the striker piercing section, which enhances the fuse safety in service handling. Compression of the inertia body and the striker to the bushing through the body in service handling due to the impossibility of their motion enhances the fuse safety and prevents formation of dents on the body, which results in preservation of fuse sensitivity and enhancing of reliability of its action.

EFFECT: enhanced reliability of fuse operation and safety in service handling of ammunition.
