Leonardo da Vinci Parachute
Leonardo da Vinci Parachute most likely came about as he was testing the feasibility of one of his flying machines. Although he himself probably did not get into any of the machines (most likely one of his apprentices – Leonardo would have been an old man at the time) he still would have realized that the designs were unstable and/or downright dangerous.
When did leonardo da vinci invent the parachute is dated to 1485, and Fausto Veranzio or Faust Vrančić (1551–1617) studied Leonardo da Vinci’s sketches of the parachute and kept the square frame, but replaced the canopy with a bulging sail-like fabric, which he realized was slowing the More efficient in terms of fall speed.
As you can see from the image below, it simply shows a man hanging onto the parachute by his bare hands – it is a very simplified design and Leonardo da Vinci invented parachute.
To the left hand side of the parachute drawing are the words (in typical mirror writing) –“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.”
He clearly had confidence in his own design and had done some mathematical calculations, possibly based on some of his wind resistance and friction studies. But the question remains.
So essentially, combining the glider, parachute, landing gear and helicopter, Leonardo almost invented all modern forms of air transport, unfortunately as is nearly always the case, Leonardo was born several centuries before the rest of humanity and the science of the time was ready for him.
