NOSE FUSE Russian patent published in 2004 - IPC

FIELD: remote combination double-action (impact and time) fuses.

SUBSTANCE: the nose fuse for small-caliber artillery cartridges has a body, in which coaxially in succession positioned are the central rod pressing the end of the tapered fairing by the supporting head, axial firing pin, primer cap, shutter of the fire-transfer channel with a powder charge, delay pellet plug and a safety device of the radial detonating cap coupled by means a pyrotechnic channel to the self-destruction pricking mechanism a peripheral annular groove with radial inclined slots is made in the body under the tapered fairing positioned in which are the balls of the impact reaction mechanism of the axial firing pin resting on the helical lock of the inertia cocking mechanism positioned inside the movable bushing installed over the annular groove of the mounting support. The novelty is in the fact that the axial firing pin of the primer cap is fastened in an additional striker mounted for longitudinal movement relative to the body in the annular groove of the mounting support, under which a receiver is made in the axial fire-transfer channel.

EFFECT: enhanced functional reliability and sensitivity of the nose fuse at limit angles of impact of the shell with the target at low speeds of its flight at the maximum range.
