The M.P.C.

Description::The M.P.C., or M.ulti-P.rojectile C.annon, is a large, mounted cannon made to fire anything with a diameter of up to six inches. It uses a bottom fitted combustion chamber with two secondary oxygen chambers to launch the load from the cannon. For projectiles smaller than six inches in diameter, a projectile casing is used to fill the entire barrel to create the needed seal for the cannon to fire.

Below is a blueprint created by -Nutz- for the M.P.C.

Current Cannon News
Ok everyone, Zerm and I have now completed the prototype pressure cannon for the M.P.C. The prototype, which has yet to be named, was created over the Christmas/New Years holiday. I hope that Nova will soon post the pictures that he was supposed to take of the cannon. I am also going to change a few things on the M.P.C. blueprints when I can get around to it.

Recent Changes
v0.6
 * Realization that 6in. diameter barrel is frickin' HUGE. Dropping down to 4in.
 * We will be changing the M.P.C. over to an air-pressure cannon, leaving behind the usage of combustion

v0.5
 * Usage of High Density Polyurethane
 * Implementation of two secondary tanks for added oxygen
 * Altered Projectile Casing slightly to lower chance that casing may obstruct projectile path on break away

ToDo List

 * Choose the stand for the MPC
 * Design stand for MPC
 * Design Ignition system

Past Blueprints
v0.1 (Original Idea) This blueprint was the original idea for the Multi-Projectile Cannon. It became obsolete on 9/16/06 when Zerm noticed two things. One, using PVC for the combustion chamber would be highly dangerous due to its low strength and its nature to shrapnel when it explodes. It was devised that the best way to have a maximum level of strength is to use High Density Polyurethane, and to make the main combustion chamber shorter in length. Secondary chambers were added only to house extra oxygen for the combustion. With the addition of these chambers, more fuel can be placed inside the combuston chamber to fire larger loads.
