NOSE FUSE Russian patent published in 2011 - IPC F42C9/14 

FIELD: explosives.

SUBSTANCE: nose fuse for small-calibre artillery cartridges comprises the following coaxially mounted components - an actuator beam detonating cap, an aggregate unit, the axial fire-sending channel of which, equipped with an output throttling hole, there are the following components mounted - a centrifugal gate, a membrane gate, a transverse bolt, equipped with a combustible powder stop, and a central detonating cap, and a self-destruction detonating cap is installed parallel to the latter with the possibility of longitudinal displacement towards a stationary sting and is connected by a pyrotechnical channel directly to the detonating cap. At the same time the stepped sting of the central detonating cap is equipped with an inertial triggering mechanism, comprising a helical stop installed inside a bushing arranged above a circular bore in a transverse link, and is connected to an impact reaction mechanism, balls of which are placed in radial inclined slots of the body connected to its peripheral circular groove closed with a fairing coupled with a monolithic head end of the body. The pyrotechnical channel of the self-destruction device and the powder stop in the bolt of the axial fire-sending channel adjoin a circular gap between the body and the aggregate unit, where there is a receiver to accumulate gaseous products of their combustion, besides, the pyrotechnical channel with a throttling hole directed towards an actuator detonating cap, is connected via an intensifying charge in an expansion chamber.

EFFECT: increased functional reliability and safety of fighting application of a nose fuse according to its designation.
