Leonardo da Vinci printing press model
Leonardo da Vinci printing press is an exact replica of his original design. This is a small wooden snap together set and no gluing is required. This model also shows the mechanics Leonardo designed to operate the printing press.
Leonardo da Vinci paddle boat model
Leonardo da Vinci Paddle Boat is of plastic construction and is a snap together set, as a result there is no gluing required. Leonardo’s Paddle boat is one of the first paddle boats ever designed. The paddle boat would remain in operation for hundreds of years until the invention of the marine propeller.
Leonardo da Vinci’s machine gun model
Leonardo da Vinci machine gun was the first auto-firing weapon ever invented. He designed it in such a way that when it was first fired another set of barrels would rotate around and ready to fire almost immediately. Like most of his inventions for war this machine was supposed to break the spirit of the enemy through fear.
Leonardo da Vinci helicopter model
Leonardo da Vinci Helicopter model is based on his original sketch. It is of wood and canvas construction (exactly as it should be) and this model simply snaps together and no gluing is required.
leonardo da Vinci catapults blueprints
Leonardo da Vinci catapult models are both simple and ingenious. The mechanical catapult involves a pawl and rachet system which incrementally tightens the firing system. As the system is tightened, the forces put into the system by the operator (1 soldier) are transferred to both the ropes and tension arms of the catapult. For catapult locking mechanism, on releasing the firing pin (the pawl), the stored energy is instantly transferred from the ropes and tensioning arms to the swing arm which would contain a lead ball/cannonball.
What does a catapult look like – this machine looks like it could have been operated by a handful of soldiers: four or five soldiers for moving/repositioning/aiming the catapult and 2 men for operating the machine – one to tighten the mechanism and one to release the firing pin.
Interesting facts about catapults – this machine would undoubtedly have wrought havoc upon any castle/fort it attacked. It could be reloaded and retightened very quickly. For catapult firing, as with all medieval catapults, the soldiers may have decided to fire flaming ballistics or even disease-ridden dead bodies into the castle they were attacking – this usually spread either fire or disease very quickly within the walls of the target castle/fort. Within a castle that is under sustained attack, water supplies quickly begin to dwindle and the population begin to grow weak due to lack of food, thereby decreasing their odds of putting out any flames and increasing their odd of succumbing to illness from disease-ridden bodies flung over the walls.
Who invented the catapult – catapults were used in the early 4th century BC. which was invented by Greek Diodorus Siculus in 399 BC as part of the equipment of the Greek army.
