Detail of Leonardo's "aerial screw" The page of Paris Manuscript B, folio 83v, that depicts Leonardo's aerial screw, held by the Institut de France The Italian polymath Leonardo da Vinci drew his design for an "aerial screw" in the late 1480s, while he was employed as a military engineer by Ludovico Sforza, Duke of Milan from 1494 to 1499.
The idea of vertical flight has been around for thousands of years, and sketches for a VTOL (helicopter) show up in Leonardo da Vinci's sketch book. Manned VTOL aircraft, in the form of primitive helicopters, first flew in 1907, but would take until after World War Two to be perfected.
Paul Cornu's helicopter of 1907. Experimental helicopter by Enrico Forlanini (1877), exhibited at the Museo nazionale della scienza e della tecnologia Leonardo da Vinci of Milan. The early work on powered rotor lift was followed up by later investigators, independently from the development of fixed-wing aircraft.
The Vitruvian Man, c. 1490. Leonardo da Vinci (1452–1519) was an Italian polymath, regarded as the epitome of the "Renaissance Man", displaying skills in numerous diverse areas of study.
Leonardo da Vinci's ornithopter design. In 1841, an ironsmith kalfa (journeyman), Manojlo, who "came to Belgrade from Vojvodina", [2] attempted flying with a device described as an ornithopter ("flapping wings like those of a bird").
Leonardo Da Vinci's baptism record. Leonardo da Vinci, properly named Leonardo di ser Piero da Vinci [b] ("Leonardo, son of ser Piero from Vinci"), [9] [10] [c] was born on 15 April 1452 in, or close to, the Tuscan hill town of Vinci, 20 miles from Florence.
In the late fifteenth century, Leonardo da Vinci followed up his study of birds with designs for some of the earliest flying machines, including the flapping-wing ornithopter and the rotating-wing helicopter. Although his designs were rational, they were not based on particularly good science. [9]
In the 15th century, Leonardo da Vinci published the Codex Leicester, in which he rejected Aristotle's theory and attempted to prove that the only effect of air on a thrown object was to resist its motion, [7] and that air resistance was proportional to flow speed, a false conclusion which was supported by Galileo's 17th century observations of ...
