Charges, propelling, for cannon

Arsenal extended to the year 1902, and the history of the depot was one of gradual construction with the ultimate idea of an establishment for the storage of powder. However, a few years before the Spanish American War, the depot began assembling powder charges for cannon. This propellant charge loading, Picatinny s first production activity, has never ceased... 

The bursting charge is, like a cannon, both the explosive of the shell and at the same time the propellant for the stars. It must produce an explosive force which can be adjusted by the strength (thickness) of the shell. This phenomenon is not detonation, but quick burning. A high explosive which detonates destroys the stars and is difficult to use as a bursting charge. 

They had never bothered to ponder the inconvenient fact, for instance, that the gunpowder propelling every bullet and the explosive charge inside every cannon shell were made from nitric acid, and that nitric acid was manufactured from nitrate that arrived on ships from Chile. The fragile supply lines across the Atlantic now were blocked by British warships.

Ever since the invention of NC and NG, attempts were made to apply them either by themselves or in mixtures for military purposes. Under the term uses for military purposes may be understood propellants in rifle, cannon, rocket and pyrotechnic ammunition booster and bursting charges in bombs, grenades, mines (land and sea), artillery projectiles, warheads of torpedoes and of rockets, etc military blasting operations, military cratering, military demolition, military excavation and production of antitank ditches... 

Rocket propellants are similar to the propellant charge powders discussed above, because they combust in a controlled manner and do not detonate. However, propellant charge powders burn considerably quicker than rocket propellants, which results in a significantly higher pressure for gun propellants in comparison with rocket propellants. Typical pressures in the combustion chambers of rockets are 70 bar, which can be compared with up to 4000 bar for large artillery and NAVY cannons. 

For those deeply concerned about perimeter defense of their property, there is the Queen of Battle, artillery. A compressed air powered cannon is easily constructed. Building them is so simple that I ve seen them featured on the Junkyard Wars TV show. The bore size of the cannon can be chosen so that the common aluminum soda pop can will fit perfectly. This can, once loaded with an explosive charge, makes an efficient projectile. Air cannons easily propel a loaded soda can 100 yards or more. For details on building an air cannon, see US Patent 4,703,869. Your local library will gladly send for a copy of the patent upon your request. You can also read the body of the patent minus the drawings by going to the US patent office website, and typing in the patent number.
