Abstract
A fuze for a projectile intended to be fired by a cannon by ignition of a propellant charge using an electric igniter. This fuze is allowed to pase from a safety position to an armed position following the fire by releasing at least two different safeties. This fuze includes a capacitor which is intended to be connected to the electric igniter and which charges during the ignition of the propellant charge, and also a computer which detects the charge of the capacitor in order to allow the arming of the fuze when this charge is greater than or equal to a reference value, the charge of the capacitor constituting a first fire safety.

A fuze for a projectile intended to be fired by a cannon by ignition of a propellant charge using an electric ignition means, wherein the fuze is allowed to pass from a safety position to an armed position, following a fire, by releasing at least two different fire safeties, wherein the fuze comprises a capacitor which is intended to be connected to the electric ignition means for igniting the propellant charge and which charges during the ignition of the propellant charge, and the fuze also comprises a computer which detects the charge of the capacitor in order to allow the arming of the fuze when this charge is greater than or equal to a reference value, the charge of the capacitor constituting a first fire safety.
A method of arming a fuze fitted to a projectile when fired by a cannon, in which method a fire is recognized by the detection of at least two different events usually associated with a fire, the combination of the two events making it possible to arm the fuze, the method comprising the following steps:
- a capacitor of the fuze charges from a signal for firing a propellant charge,
- the charge of the capacitor is used as a first event associated with the fire and allowing the arming of the fuze, a computer detecting the charge of the capacitor in order to allow the arming of the fuze when this charge is greater than or equal to a reference value.
