NOSE PERCUSSION FUSE Russian patent published in 2003 - IPC

FIELD: combination fuse of double action, time and percussion, actuated by inertia movement of mechanisms at an impact with an obstacle and on expiration of the preset time period from the instant of the shot. SUBSTANCE: the nose percussion fuse for small-caliber artillery cartridges has a detonator aligned with the warhead, with a safety device installed between them, percussion inertia mechanism with a ball kinematically linked with the conical fairing of the body, with a retarder, and an inflammation device linked with the pyrotechnical charge of the beam self- destruction primer detonator. The novelty is in the fact that the inertia cocking mechanism is made as a power source and represent a self-actuating electrolytic battery with a RC-network of retardation closed to a photon-coupled pair linked with an igniter, which via a centrifugal contactor is connected to the power source, and the ball of the percussion inertia-reaction mechanism is loaded by the spring-loaded contact of the switch of the electric detonator adjoining the beam self-destruction primer detonator and electrically closed by means of the contacts of the gate throttly of the safety device, that is fixed by the gate of the powder lock communicating with the electric igniter. EFFECT: enhanced functional reliability of the simple construction of the combination double-action nose percussion fuse, contact at various impact angles and contactless in the trajectory of flight, time for self-destruction, enhanced accuracy of operation of the actuating mechanisms. 5 dwg
