NOSE FUZE Russian patent published in 2008 - IPC F42C9/14 

FIELD: explosive works.

SUBSTANCE: invention concerns the detonators of the double action working from inertial moving of mechanisms at contact with a barrier and after the set time interval from the moment of a shot which is intended for use in automatic and rifle-attached grenade launchers. The nose fuze contains the executive cap-detonator closed with gate valve of the safety mechanism, having the spring drive equipped with a rod stopper, and the shock impact reactionary mechanism, kinematically connected with conic case aerodynamic shroud, and also the power supply executed in a kind of electrically connected with electronic control block of self-activating battery which glass ampoule is mounted in lamellar electrodes with possibility of longitudinal moving against the tip. The sustainer firing package cooperates with a beam cap-detonator. The glass ampoule of the electrolythic battery is loaded by the massive plug. In the central window of the plug it is placed, over a metal cap of the damping casing, a contact ledge of the spring-actuated metal cover of the conic aerodynamic shroud, leaning against the spiral spring established in a ring groove of the case, as a group carrying out functions of the impact power mechanism. The beam cap-detonator is mounted in the gate valve of the safety mechanism with the rod stopper is fixed on centrifugal carriages. As the electronic block the microcircuit with the management program the structural elements, connected with the reception aerial mounted on conic aerodynamic shroud is used.

EFFECT: safety during usage and shooting, increased hypersensibility, especially at a contact with rebounding corners and with soft ground.
