Fighting Kites
Another activity grew out of festivals of kite flying - kite
fighting. It seems to have been well established in China and
Korea, but it was not taken up as quickly by the Japanese. However,
in those communities where kite fighting caught on, the participants
were exceptionally enthusiastic. Perhaps it offered a welcome
escape from the formality of society and harsh living conditions
in rural areas.
A fighter kite is usually small and highly maneuverable. Its
string is partly coated with powdered glass, sharp sand, ground
pottery, or even knife blades. The kite flyer attempts to bring
down his opponent's kite by cutting its line. It takes skillful
maneuvering to cross other kite lines to cut them. In Japan
today, the Nagasaki fighters are the best known participants
in this type of competition.
Kites in Europe
Several forms of kites and windsocks appear in writings and
drawings as far back as A.D. 105 when the Romans used a windsock
as a military banner. In the fifteenth century Leonardo da Vinci
developed a method for spanning a gorge or river with the help
of a kite. Later, in the 1850s, his method was used at Niagara
Falls to make possible the construction of one of the first
large suspension bridges. Experimenting with kites, da Vinci
became interested in flight and he drew many designs for flying
machines. His interest in kites may have led him to study clouds
and air currents which inspired him to invent a parachute and
draw diagrams for a helicopter. While his ideas impress scientists
and engineers today, da Vinci seems to have viewed them as minor
accomplishments since they had grown out of ideas based on a
child's toy.
By the seventeenth and eighteenth centuries kites became commonplace
and quite popular, but they probably were seen as a diversion
for children. The first use of kites for scientific purposes
was in 1749. In Scotland, Alexander Wilson conducted experiments
to measure temperatures at different altitudes. In order to
do this, he raised several kites in train (several kites attached
to the same line so that they fly at varying heights). He attached
thermometers to each kite and was thereby able to measure the
temperature at each altitude.
Kites in the United States
As a child, Benjamin
Franklin enjoyed experimenting with kites. Writing about
one of his experiments, he tells how his kite pulled him across
his favorite swimming hole in "a most favorable manner." In
June 1752, he flew a kite in a rainstorm in order to prove that
lightning had the same properties as the electricity being generated
in laboratories. With a key attached to the line with silk ribbon,
he stood in a doorway so he could keep the ribbon dry. When
lightning struck the drenched kite, fiery streaks sparked around
the key. The dry silk ribbon was the only thing between Ben
and the electrical jolt traveling from the sky!
Early pioneers in aerodynamics conducted an amazing variety
of experiments as they attempted to produce structures that
would enable people to fly. Many of these experiments involved
the use of kite-like constructions. Kite technology enabled
scientists and engineers to develop an understanding of aerodynamic
principles that eventually led to the sophisticated types of
air travel available to us today.
American diplomat and scientist Benjamin Franklin experimented
with kites to investigate atmospheric electricity, and kite
studies were also made by the American physicist and inventor
Alexander Graham Bell. Beginning in the 1890's and continuing
for about 40 years, box kites, consisting of two or more connected
open-ended boxes, were used for sending meteorologic instruments
aloft to measure wind velocity, temperature, barometric pressure,
and humidity.
On November 12, 1894, Lawrence Hargrave was lifted from the
ground by a train of four of his "cellular kites". This was
simply one stage in his quest for a stable lifting surface which
could then be powered and used as a means of transportation.
Hargrave was doing his utmost to invent the aeroplane!
Hargrave developed several styles of kites and gliders, refined
and developed the concept of curved surface wings, and also
invented the rotary engine. He never patented any of his inventions,
preferring them to be available for the advancement of mankind.
He made scathing attacks on people who experimented in secrecy
with the intention of profiting from their inventions, accusing
them of trying to exploit humanity.
On November 7 1903, Samuel Franklin Cody actually crossed
the English Channel on a vessel towed by kites.
