Abstract
An electronic switch for projectiles includes a circuit with a source of electric energy which is switched in when the projectile is discharged. The circuit includes an adjustable time-delay device for the explosion of the projectile, a device for preventing muzzle burst, and a self-destruct arrangement. The exploding fuse is connected to the source of energy by an impact or a proximity switch. The self-destruct arrangement is settable by cooperating cells carried by the projectile and by the barrel of the gun.
Claims8
Electronic fuse for projectiles having a switch, a detonator and an explosive charge, said fuse comprising a source of electrical energy, means responsive to discharge of the projectile to render said energy source operative, a control mechanism for preventing muzzle burst, an adjustable mechanism for determining the time delay of explosion and a programmable self-destruct mechanism, all said mechanisms being connected to said energy source, said mechanisms being provided with control elements and formed as self-contained units, the control mechanism including an electronic integrated circuit having an anode-cathode connection with a thyristor in the anode-cathode connection and a trigger diode.
Electronic fuse for projectiles having a switch, a detonator and an explosive charge, said fuse comprising a source of electrical energy, means responsive to discharge of the projectile to render said energy source operative, a control mechanism for preventing muzzle burst, an adjustable mechanism for determining the time delay of explosion and a programmable self-destruct mechanism, all said mechanisms being connected to said energy source, the source of electrical energy being a battery provided with a direct voltage transformer.
Electronic fuse for projectiles having a switch, a detonator and an explosive charge, said fuse comprising a source of electrical energy, means responsive to discharge of the projectile to render said energy source operative, a control mechanism for preventing muzzle burst, an adjustable mechanism for determining the time delay of explosion and a programmable self-destruct mechanism, all said mechanisms being connected to said energy source, said fuse including a firing condenser, said muzzle burst preventing mechanism including means to connect said condenser to the energy source after the passage of a predetermined time from discharge of the projectile, whereby the energy for firing the detonator is stored in the condenser, said connecting means including a resistance means connected in parallel to the firing condenser to cause the firing current to decrease according to an exponential function.
Electronic fuse for projectiles having a switch, a detonator and an explosive charge, said fuse comprising a source of electrical energy, means responsive to discharge of the projectile to render said energy source operative, a control mechanism for preventing muzzle burst, an adjustable mechanism for determining the time delay of explosion and a programmable self-destruct mechanism, all said mechanisms being connected to said energy source, means independent of the energy source for programming the self-destruct mechanism, said programming means including a coil in which current can be induced by a magnetic field producing means at the muzzle of a gun.
