Fuse device for a projectile

Abstract

A mortar includes a fuse device having a detonator, and a firing booster arranged to be ignited in response to detonation of the detonator. The detonator is detonated by a firing pin which comprises part of a sliding component in an electric solenoid mechanism. Upon receipt of an electric firing signal, the solenoid produces an electromagnetic force that thrusts the firing pin against the detonator.

What is claimed is:  
     
         1 . A fuse device comprising: 
 a casing;    an initiating detonator disposed in the casing;    a firing booster arranged to be ignited in response to detonation of the initiating detonator; and    an electromagnetic power device for detonating the initiating detonator, comprising a firing pin displaceable toward the initiating detonator under an electromagnetic force generated in the power device.    
     
     
         2 . The fuse device according to  claim 1  wherein the power device comprises an electric solenoid having a cylinder and a slidable element disposed in the cylinder, the sliding element including the firing pin.  
     
     
         3 . The fuse device according to  claim 1  wherein the fuse device is operable in response to receipt of an electric signal from an electronic firing system in the fuse device.
