One of the machines he designed was the aerial screw. This machines ' design would later be used to create the modern day helicopter, as this contraption had a similarly shaped rotor to what is used in the rotors of today 's helicopters. His sketches demonstrated that the aerial screw would be powered by men rotating a crank that was located on the central platform. Although it wouldn’t really work due to the machines ' weight, it still opened the eyes of many to what could be possible in the field of aviation (Helicopter). While working on these flying machines, it was most likely that Leonardo Da Vinci realized that he should invent something that would save a person if his flying contraptions were to fail mid-flight. This was probably the reasoning behind his next big invention, the parachute. First drawn in 1483, (Leonardo Da Vinci: The Invention of the Parachute) the parachute 's intended purpose was to allow a person to theoretically land safely if they were to fall from thousands of feet in the air. Although his parachute 's canopy was triangular instead of rounded, it still opened the idea of the modern parachute we see today. His design was criticized because of the weight caused by the parachute 's materials, but this design was proved …show more content…
From designing deadly weapons which induced fear to producing flying machines which proved that human flight was possible, to even designing and innovating smaller machines that made people 's ' lives a bit easier, Da Vinci 's inventions have earned him the title of the world 's most famous engineer as he invented and designed contraptions which were the basis for the engineering marvels we see
