| This design hearkens back to WWII and the German V-3 super-cannon. The idea was to have multiple powder charges detonated in side ports as a round traveled down the barrel. I've drawn out a simple way that the same thing could be done with pneumatics. Chamber 1 in the picture is a standard setup with a 90 degree piston valve. A spud is fired in the usual manner. As it travels down the barrel, it passes a pneumatic piston. As the spud keeps going, the high pressure pushes the piston up. This action opens the piston valve on Chamber 2. | ||||||||||

| In red, I've marked what I call the "timing distance." This distance is a function of the speed of the spud and the time it takes the piston to open the second valve. Ideally, the distance should be such that the spud passes the second valve port just as the valve begins to open. This system negates the need for complicated electronics and could be duplicated many times down the length of the barrel. |
