19,00 €Helicopter Leonardo da Vinci Italeri This machine, which is considered the ancestor of the modern helicopter,appears in a drawing dated roughly 1480 contained in theCodex Atlanticus. Leonardo outlines the plan for an “aerial screw”imagining it as a worm screw with a diameter of approximately 5metres, in his intentions, it should have “screwed itself” in air takingadvantage of its density. Moved by the muscle strength of four menwalking on the central platform, it consisted of a wooden structurecovered with starched linen cloth. Since there is no proof that Leonardoactually built the machine he imagined, it remains one of hismany theoretical insights. Per saperne di più -

18,00 €The catapult was a medieval weapon which Leonardo reworked and improved upon. As shown in the drawings on page 140a/br of the Atlantic Code, which represent six designs of a spoonshaped catapult, the loading mechanism is activated by two large flexible wooden arms that increase launching power. The stone or metal projectile is placed in the spoon-shaped end of a long lever. The loading operation turns the large central pin and flexes the curved wooden arm. The safety catch is then released to launch the projectile straight at the target. The launching power is proportional to the length of the lever arm and so the energy involved in throwing the projectile is high, allowing the projectile to cover particularly long distances.
