P.A.C. 4 - Pressurized Air Cannon

P.A.C. 4 with P.A.C. 1

Information:

This cannon can shoot a flare projectile over 400 yards. At 70PSI, a lemon shot through 1/2" plywood (about 100 ft. from the target). This is pretty powerful and this calls for great caution in the firing of the cannon. The over-all length of this cannon is about 5 1/2ft. It has a 3in. X 3.6ft. chamber. It uses two solenoids....Why you ask??? Why not use two valves to double the air flow. Now this might not give twice the distance but it will surely increase the range of the projectile. The air pressure pushing the spud is not the only thing that gives it it's speed . The real factor here is the volume of air pressure along with the speed at which it is being delivered or moving.

Like mentioned earlier, the dual-valves make it possible for greatly improved distances. In the picture to the left, you can see how the dual-valves work. The picture also shows part of the electronics. The firing system has a safety toggle-switch, and a firing momentary-switch. The construction of the cannon is pretty straight forward but if you would like to order plans on how to build this cannon you can do so here. Click Here for plans

These diagrams are of the P.A.C. 4 without the barrel attached. These diagrams should help you understand how the cannon is constructed.
