Remotely controlled apparatus to fire a projectile.

摘要

1. A device intended to remotely control the detonation of a projectile (2) fired by a weapon (1) and comprising, on the one hand, a transmitter (3) connected to a fire control unit (6) and sending a programming signal (5) to the projectile (2), this signal carrying the delay-time information and, on the other hand, a receiver (4) incorporated into the projectile, designed to process said information and to detonate said projectile, said receiver comprising a shaping element (10) which changes the programming signal into a command signal consisting of a series of pulses, and a counter, called counter-analyser (23), intended to count the oscillations supplied by a clock (14), the number of oscillations counted between two successive pulses of the command signal constituting an image of the delay period which is used for detonating the projectile, a device characterized in that the programming signal (5) carries several successive items of delay-time information having decreasing values taking into account the distance covered by the projectile (2) between the reception of each item of information, and the receiver (4) includes a comparator, called comparator-validator (29), capable of comparing the number of oscillations counted by the counter-analyser (23) between two successive pulses of the command signal to a reference value and capable of resetting the counter-analyser (23) if this reference value is smaller than the counted value.
