Was an Italian Renaissance

polymath: painter, sculptor, architect, musician, mathematician, engineer, inventor, anatomist, geologist,

cartographer, botanist, and writer. His genius, perhaps more than that of any other figure, epitomized the Renaissance humanist ideal.

Слайд 3Designed for pure intimidation, da Vinci’s crossbow was to measure

42 braccia (or 27 yards) across. The device would have

six wheels (three on each side) for mobility, and the bow itself would be made of thin wood for flexibility.

Crosbow

Designed for pure intimidation, da Vinci’s crossbow was to measure 42 braccia (or 27 yards) across. The

Слайд 4helicopter measured more than 15 feet in diameter and was

made from reed, linen and wire. It was to be

powered by four men standing on a central platform turning cranks to rotate the shaft. With enough rotation, da Vinci believed the invention would lift off the ground

Helicopter

Слайд 5Design for a Flying machine

Слайд 6The pilot would lie face down in the center of

the invention on a board. To power the wings, the

pilot would pedal a crank connected to a rod-and-pulley system. The machine also had a hand crank for increased energy output, and a head piece for steering. As the busy pilot spins cranks with his hands and feet, the wings of the machine flap.

Слайд 7Da Vinci made a sketch of the invention with this

accompanying description: "If a man have a tent made of

linen of which the apertures (openings) have all been stopped up, and it be twelve braccia (about 23 feet) across and twelve in depth, he will be able to throw himself down from any great height without suffering any injury."

Parachute

Da Vinci made a sketch of the invention with this accompanying description:

Слайд 8Da Vinci’s vehicle has a number of light cannons arranged

on a circular platform with wheels that allow for 360-degree

range. The platform is covered by a large protective cover (much like a turtle’s shell), reinforced with metal plates, which was to be slanted to better deflect enemy fire. There is a sighting turret on top to coordinate the firing of the canons and the steering of the vehicle.
