Abstract

A device, and method for using the device, for extracting a large-caliber projectile jammed in a barrel of a weapon including a solid body having a diameter smaller than the caliber of the barrel and intended to be introduced into the barrel at the muzzle of the latter and then released in the barrel in order to impact, by inertia, the jammed projectile. The device is at least two radially expandable locking mechanisms, each able to move between a locked position in which it is applied radially against the inner wall of the barrel and a released position in which it is not applied against the barrel, the passage of the locking mechanisms from one position to the other by an expansion apparatus, the device includes a translation device enabling a first locking mechanism to be translated axially to a second locking mechanism.

Dependent claims

An extraction device for extracting a large-caliber projectile jammed in a barrel of a weapon, the extraction device comprising:

a solid body, the solid body having a diameter smaller than a caliber of a barrel and the solid body being configured to be introduced into the barrel at a muzzle of the barrel and is configured to then be released in the barrel in order to impact by inertia the projectile jammed in the barrel,
at least two radially expandable locking locks, each of the plurality of locks being configured to move between a locked position in which one or more of the plurality of locks are applied radially against an inner wall of the barrel and a released position in which one or more of the plurality of locks are not applied against the barrel,
an expansion means configured to move each of the plurality of locks between the locked position and the released position, and
a cylinder configured to axially translate a first lock of the plurality of locks with respect to a second lock of the plurality of locks.
