Did leonardo da vincis invention of the helicopter really fly ?
“Leonardo Da Vinci Da Vinci’s vaunted spiral design created in 1490, called the Helical Air Screw, has often been cited as the first serious attempt to produce a working helicopter (Sadler 1). Da Vinci himself quoted on the device: “…I have discovered that a screw-shaped device such as this, if it is well made from starched linen, will rise in the air if turned quickly…” (History of Helicopters 1). However, this was only an experimental design and was never put into practical use. “Da Vinci was in this instance no more than an experimental engineer, putting onto paper age-old principles” (Sadler 1). Without adequate technology the ability to create such machines was virtually impossible during this time.” Source and further information: http://asms.k12.ar.us/classes/humanities/amstud/97-98/helicptr/webpage.htm “For much of his life, Leonardo was fascinated by the phenomenon of flight, producing many studies of the flight of birds, including his c. 1505 Codex on the Flight of Birds,
