Thanks Neil, I never thought that 'Fire as fast as you can' was used (I never asked as I haven't got that far yet) I was going for the scaled down firing interval so was designing a 'slow' breech!
Now if it's acceptable to run as fast as possible, I'll need to do some tests on paintballs to see how much acceleration they can take in the loading process. It's possible to achieve quite high cyclic rates using a variation on the three barrel Vulcan design, but I doubt it would be very useful to fire 40 paintballs in under a second. Just think of the trips to base to re-arm. Realistically, single shot, 60/90/120 shots per min, would be quite straight forward, just need to decide weather to fire from an open or closed breech position. Probably stick to the rotating breech principle; just vary the number of ports. I'll think on this nearer the time. Ryan, My main problem with your design is the 'gate' that prevents the second paintball entering the breech. As you have it being closed by a piston driven by the initial propellant discharge, it'll hit the following paintball with somewhere about 35g acceleration with the mass of all the following balls behind it. I'm sure this is way more energy than a static paintball will take before rupturing. you'll need to have the gate set up in perfect alignment so as not to attempt to move the first following ball any more than a couple of thou at most. Almost like firing a razor bade between two touching balls without cutting or moving either one, tricky in the extreme! Phil D. -- You are currently subscribed to the "R/C Tank Combat" group.
