Kites
The kite
was invented in China, around the sixth century B.C. The inventor is not
known, because it is so old. When the Chinese flew the kite it was suppose
to free the spirit. Every year in China, on the ninth of September there
is is a annual kite flying fest. It was also used to monitor the ground.
A person would get in a kite, and someone would fly them up to the sky.
In 1771 A.D.,
Marco Polo set off to China. In 1775, he reached China, and served as an
ambassador to Kublai Khan. When he returned to Venice he brought back many
Chinese inventions, such as the kite and noodles.
The kite
is a light framed aircraft, with an aerodynamic shape. There are many fabrics
used on kites. Some of them are, paper, nylon, plastic, etc. It is flown
when a moving object runs when pulling on the string that connects on to
the kite.
There
are various uses for the kite. They are now mostly used for recreational
reasons, but there is more to the kite than just for having fun. It is
used for meteorological predictions. In World War II, the Japanese used
kites to signal people so the Armed Forces couldn't intercept their massages.
Kites were mainly used to signal people before there was radio. A famous
use of the kite was took place in the 1752, by Benjamin Franklin. He tied
a key to a kite and flew it in an lightning storm. There was a good part
and a bad part to this experiment. The bad part was that lightning hit
the kite and shocked him. Thanks to him we know that metal is and electrical
conductor.
Ever since Marco Polo brought
back the kite, it has been used widely all over the globe.
Parachutes
The parachute
evolved from the square kite. The first parachute was a wooden frame, with
paper. The parachute was placed on the back of your feet and your hands,
like a hang glider. When the idea had reached France, a aeronaut named
Jacques Ganerin refined the kite by making it into an umbrella shape, in
1764. Although the parachute was invented by the Chinese, the French got
all the credit, because they refined it. The first ever recorded decent
from a hot air balloon was in 1785.
Parachutes
are also used for military purposes, but they were mostly used in World
War II. They were used to drop cargo and paratroopers. Many people now
consider parachuting a sport along with skydiving and hang gliding. When
ever a returning spacecraft is coming back from space, a parachute is always
used to break its dive.
The parachute
pack is placed on your back. When you pull the ripcord, the pack releases
the parachute, and you decent safely to the ground.
If the kite had never been
invented then would be no parachutes, hang gliders, skydiving, or jets,
because of its aerodynamic shape.
