Abstract
A fuze for a submunition grenade including an electric detonator and primary super quick apparatus for electrically initiating the electric detonator upon percussion. Preferably, the fuze also includes self-destruct apparatus for electrically initiating said electric detonator, after a period of time, when said primary apparatus fails to initiate said electric detonator.
Claims14
A fuze for a submunition grenade comprising:
- (a) an electric detonator;
- (b) primary super quick apparatus for electrically initiating said electric detonator upon percussion;
- and
- (c) self-destruct apparatus for electrically initiating said electric detonator, after a period of time, when said primary apparatus fails to initiate said electric detonator, regardless of whether said fuze is armed or said fuze is not armed,
- wherein said primary super quick apparatus acts as a primary self-destruct apparatus to initiate said electric detonator without initiating a main charge, and said self-destruct apparatus acts as a secondary self-destruct apparatus to initiate said electric detonator without initiating said main charge.
An electronic percussion fuze with electronic self-destruct apparatus for submunition grenades comprising:
- a fuze housing;
- an electrical conductor between an external energy source and the electronic fuze;
- an electric detonator;
- primary electrical apparatus for the super quick initiation of the fuze upon impact, including a micromachine accelerometer, integrated circuit, and electric resistor bridge to the electric detonator;
- and
- an electrical self-destruct apparatus for initiation of the fuze after a predetermined delay time, including a second electric resistor bridge to said electric detonator, and said integrated circuit, said electrical self-destruct apparatus being operative both when the fuze is armed and when the fuze is not armed.
A method of initiating a submunition grenade having a fuze and an electric detonator, the submunition grenade being arranged to be ejected from a projectile, the method including the steps of:
- releasing the submunition grenade from the projectile;
- electronically counting an inhibition time;
- electrically initiating an electric detonator by a primary initiator upon percussion
- if the primary initiation does not cause the detonator to explode, electronically counting time to self-destruct;
- and
- electrically initiating the electric detonator by means of a self-destruct initiator whether or not the fuze is armed;
- wherein when said fuze is not armed, said fuze is initiated upon percussion by said primary initiator in a self-neutralization mode.
A fuze for a submunition grenade comprising:
- (a) an electric detonator;
- (b) primary super quick apparatus for electrically initiating said electric detonator upon percussion;
- (c) self-destruct apparatus for electrically initiating said electric detonator, after a period of time, when said primary apparatus fails to initiate said electric detonator, regardless of whether said fuze is armed or said fuze is not armed;
- (d) wherein said primary apparatus and said self-destruct apparatus are formed as a single unit by micromachining.
An electronic percussion fuze with electronic self-destruct apparatus for submunition grenades comprising:
- a fuze housing;
- an electrical conductor between an external energy source and the electronic fuze;
- an electric detonator;
- primary electrical apparatus for the super quick initiation of the fuze upon impact, including a micromachine accelerometer, integrated circuit, and electric resistor bridge to the electric detonator;
- and
- electrical self-destruct apparatus for initiation of the fuze after a predetermined delay time, including a second electric resistor bridge to said electric detonator, and said integrated circuit.
