Bore aiming device and method

Abstract

The invention relates to a bore aiming device for assembling a turret (1) equipped with a cannon (4) and one or more optics-based aiming systems (10), said device comprising: a deflecting target (3), which is located on the exterior of the cannon (4), flush with the muzzle brake (6) of said gun (4); and the casing (2), which is located on the exterior of the cannon (4), flush with the (4) The mobile shelter (5) is flush, and the casing (2) includes a first optical system (7) equipped with a deflection camera and a second optical system (8) equipped with a gun bore aiming camera.

Description

technical field [0001] The present invention relates to a method and device for aligning a line of sight with a line of fire, commonly called a boresighting device, for a weapon system, preferably a large caliber weapon system (75mm to 140mm). Background technique [0002] On a weapon system, a misalignment between the line of fire and the line of sight is detrimental to accurate hitting of the target. There are two main sources of misalignment. The first source of misalignment is the physical deformation of the barrel, commonly called deflection, which occurs naturally and unavoidably, both horizontally and vertically, due to the relatively heavy weight of the barrel and external conditions (rain, wind, Sun, etc.) results. This deformation results in a parallelism defect between the line of fire from the axis of the barrel and the line of fire from the muzzle of the barrel. A second source of misalignment is the shock and vibration experienced during driving and firing, ...

AI Technical Summary

Problems solved by technology

This deformation leads to a parallelism defect between the line of fire from the axis of the barrel and the line of fire from the muzzle of the barrel

A second source of misalignment is the shock and vibration experienced during driving and firing, which cause deviations from the previously calibrated alignment

The second infinite focus makes it possible to observe objects located at great distances, thereby bringing the field of view of the optical system back to the same frame of reference

[0010] Both devices have the disadvantage of having to position the camera inside the barrel

In the case of document EP 1,616,145, arranging the cameras is a time-consuming and tedious operation, especially if it has to be carried out by a single operator located in the turret

Also, it is impossible to guarantee that the orientation of the camera pushed towards the muzzle will be systematically the same for every bore aiming maneuver
