Cooling device for a gun barrel

A device for cooling a gun barrel with a cooling media, the device comprising:

• a muzzle assembly having:
• a shaft, the shaft having a first end and an axial opposite second end with a length between the first and second ends, the second end of the shaft being adapted and configured to releasably connect to an end of a gun barrel, the shaft having a bore, the bore of the shaft being adapted and configured to allow a round discharged from the gun to pass through the shaft from the second end of the shaft to the first end of the shaft;
• a baffle operatively connected at the first end of the shaft;
• a turbine assembly operatively connected to the shaft adjacent the first end of the shaft, the turbine assembly have a plurality of turbine blades downstream of the baffle and the first end of the shaft, the plurality of turbine blades being adapted and configured to rotate relative to the shaft;
• a compressor assembly operatively connected to the shaft and disposed between the first end of the shaft and the second end of the shaft, the compressor assembly having a plurality of compressor blades, the compressor blades being adapted and configured to rotate relative to the shaft;
• and
• a rotary drive tube operatively connected to a radially outward region of at least one turbine blade and a radially outward region of at least one compressor blade, the rotary drive tube being adapted and configured to rotate relative to the shaft and rotate with the plurality of a turbine blades and the plurality of compressor blades, the rotary drive tube having a plurality of outlet vents downstream of the plurality of compressor blades.
