History tells us that the first concept of man trying to defy
gravity and actually fly was through a helicopter
flight. Accounts date way back 400 BC in ancient China with a hand-spun toy made
from a stick and feather that
flew when rapidly spun between palms to generate enough lift and then released.
However, the very first, more realistic concept of a helicopter dates in the
15th century when Leonardo Da Vinci
attempted to produce a working helicopter (gyroscope). This was not made into
production since his sketch was
noted to be way ahead of his time and the period had inadequate technology and
understanding about the nature of
lift and the availability of a machine that could create such massive lift.
Several other attempts had been made over the next centuries. All these had
failed but had contributed little
advancements on the development of the helicopter. The reason of failure? Same
as that of Da Vinci’s time. From
the time of Da Vinci up to the end of the 19th century, there was no adequate
machine that was powerful enough
to generate power and create lift. until the early 1940's
