    TIL, that rotary machines guns spin to cool down.

      It’s more that using multiple barrels keeps any one barrel from heating up too quickly, and it’s easier to have multiple barrels than entire firing assemblies.

          Sure, but realistically air isn’t a good enough heat conductor for this to help much. Fixed machine guns used to use water-cooling but that’s been phased out and modern weapons simple replace the barrel when it gets too hot.

        I mean technically they spin to cool but also because they use the time it takes to rotate to unload and reload a round. Basically “1 fire, 1 move out of the way, 2 fire, 1 unload, 2 move, 3 fire, 1 load, 2 unload, 3 move, etc.” multiple reasons

        As someone else put it. No dakka, just brrt. When you have 8 dakkas in sync, you get all the -kka happening while the next barrel is already Da-, so dakka dakka turns into dadadadadadddddddrrrrrrtt
