Abstract: A cleaning device for preserving inserts of weapon barrels and/or drum inserts as well as additional weapon parts, the device having a tubular central piece, guide elements arranged distributed around the periphery of the central piece, a fluid supply device, via which fluid is fed to the cleaning device, and a rotating nozzle head with openings from which the fluid can exit. A guide device additionally integrated into the cleaning unit enables movement of the cleaning device in a motorized manner. A container is provided for receiving the fluid and is functionally connected to the fluid supply device via a pump/compressor unit and a valve. A suction turbine and/or a filter can be functionally connected by an extraction line on the guide device. The cleaning device and unit are used for cleaning and/or preserving weapon barrels and other weapon parts.

Abstract: A device and a method for performing thermal compensation of a weapon barrel of a gun having at least one weapon barrel which is mounted in a barrel cradle and in a barrel support as a prolongation of the barrel cradle. A plurality of temperature sensors are integrated into the barrel cradle and the barrel support and are connected via data lines to a data box. The data box is connected to a data processing device, which acts on actuators of the gun. The temperature at the barrel cradle and the barrel support is measured by temperature sensors. The temperature difference between upper and lower sides and right-hand and left-hand sides of the barrel cradle and the barrel support are determined. The barrel inclination is then calculated from these values, and the barrel inclination is then compensated by adjusting the orientation of the weapon barrel in its azimuth and/or elevation.
