FUSE OF A SHELL Russian patent published in 2005 - IPC

FIELD: military weapons; fuses for mining and construction industries.

SUBSTANCE: the invention is dealt with fuses for shells of the volley fire reactive artillery systems. The substance of the invention is, that the fuse containing an inertia switch, a power supply, an electronic clockwork device, a safe-cocking gear located in a body and containing a rotor, an initial firing element-igniter and the rotor rotation drive with a starting electric igniter and a pusher, - is added with an inertial spring-loaded stopper being a spinning shaft of the rotor, a check made out of a distorted material, for example, out of copper to keep the rotor in its starting position, a holder made out of a distorted material and intended to block the rotor in the cocked position. Leads of the starting electric igniter are connected with an output of the electronic clockwork device, and terminals of the inertia switch are connected to an input of the electronic clockwork device. The lower part of the rotor has a cylindrical ledge entering a hole of the body. The inertial spring-loaded stopper has a stepwise cylindrical form with the geometrically bound ledges of the rectangular form on butts. The pusher of the rotor rotation drive is made in the form of a cap connected with the starting electric igniter. The technical result is an increased reliability of the fuse due to use of a longitudinal overload for its cocking, and also an increase of safety due to connecting up a circuit of cocking only after actuation of the inertia switch.

EFFECT: the invention ensures increased reliability of the fuse and its increased safety.
