Abstract

A set for and method of positioning and aligning a disruptor for the deactivation of a target and including a firing axis, a firing direction in terms of position and orientation relative to the target. The method including disposing a laser, adapted to emit beams along an aiming line, at a distance from the target such that the aiming line of the laser is coaxial with the firing direction. The disruptor is interposed between the laser and the target and positioned and oriented to make the firing axis thereof coaxial with the aiming line, by means of a flat mirror mounted at the rear of the disruptor and disposed perpendicularly to the axis of the disruptor. The mirror reflects a beam to the laser that is coaxial with the aiming line and emitted by the laser onto a mark on the mirror and centered on the firing axis.

First claim

The invention claimed is:

1. A method of positioning and aligning a disruptor adapted for the deactivation of a target and comprising a firing axis, and a desired firing direction in terms of position and orientation relative to the target, the method comprising:
disposing a laser, adapted to emit beams along an aiming line, at a distance from the target, such that the aiming line of the laser is coaxial with the desired firing direction;
interposing the disruptor between the laser and the target;
positioning and orienting the disruptor so as to make the firing axis coaxial with the aiming line of the laser, by means of a flat mirror mounted at a side of the disruptor proximate to the laser and disposed perpendicularly to the firing axis and sending back to the laser a reflected beam which, while being coaxial with that aiming line, is emitted by the laser and reflected by the mirror onto a centering mark centered on the firing axis.

2. The method according to claim 1 , wherein positioning and orienting the disruptor comprises orienting the mirror so as to make it perpendicular to the aiming line of the laser, then moving an assembly comprising the mirror and disruptor through translations such that the aiming line of the laser is intercepted by the mirror at the location of the centering mark.

3. The method according to claim 1 , wherein the laser is positioned at least three meters away from the target and the disruptor is positioned such that a distance between the flat mirror and the target is less than a distance between the flat mirror and the laser.
