Chiriaco Summit in Riverside County, California — The American West (Pacific Coastal)
Leonardo da Vinci Weapons of War & Invention
A typical cannon of Leonardo's age was cast in iron or bronze, had a short barrel, a short range, and fired cannonballs which fitted very approximately. This first thing we know Leonardo did was to design breech-loading cannons as against muzzle-loading. They required a fast means of being cooled before another firing, and Leonardo calculated that a vat of water would do the trick. By using several canons in rotation, you could be firing one, loading another, and cooling the third.
Leonardo was the first to measure the penetrating power of a missile and to ascertain how to vary it by changing the attitude. During these tests he even managed to launch a rocket-powered cannonball ten thousand feet into the air.
