Why Were Kites Invented?
The first kites were what we today would call prototype kites: they were made of light wood and cloth. They were designed to mimic a bird's natural flight. The f irst Chinese kites were used for measuring distances, which was useful information for moving large armies across difficult terrain. They were also used to calculate and record wind readings and provided a unique form of communication similar to ship flags at sea.

This occurred a millennium later, when the kite was flown in order to appeal for help during the siege of Nanjing. Paper kites are still used in China, but are seen as more of a traditional art than a viable pastime.
Who invented the kite?
Around 1900, Orville and Wilbur Wright, self-taught aeronautical engineers in Ohio, began testing their biplane designs as kites. The Wright brothers were the first to focus on control, which was the missing ingredient for manned flight that had other aviation pioneers stumped.

In the 1990s, with improvements and innovations in combined with innovations in kite aerodynamics came an emerging generation of maneuverable traction kites, also known as power kites. These kites were like ‘engines’, capable of enough pulling power (or traction, hence the name) to propel a craft or person across terrain such as water, snow, ice, or land. Pilots would maneuver the kite while simultaneously navigating a moving vehicle such as a land buggy that can reach speeds of 50 miles per hour.
What is a stunt kite?
There are 2 commonly-known types of stunt kites, one having 2 kite lines attached to the bridle, which arecalled dual-line control kites. Quad-line kites have four kite lines attached, which in turn, afforded the user more control and manuverability.

As time passed and people realized the potential of kites, the fighter kite was a design that quickly became popular throughout Asia. Popular designs included the R okaku from Japan, and the Tukkal from India. These kites were typically flown without tails, allowing them to be highly maneuverable. The kite lines were often coated in abrasive materials like powdered glass. In kite fighting, these agile kites and abrasive lines were used to cut down opponents’ lines till there was only 1 kite left in the sky.
What did Benjamin Franklin invent?
With this experiement, Franklin proved that lightning was a form of electricity. Franklin then went on to invent the lightning rod.
Who invented the box kite?
Lawrence Hargrave, one of the first scientists to work on kite design during this period, invented the box kite and extended kite design into the ambit of engineering. While exploring the possibility of human flight, Hargrave experimented with the goal of a design that would be stable during flight.
When were flexi wing kites invented?
Another innovation in kite design was Francis Rogallo’s flexi-wing kite created in 1948, which eventually became the basis of hang-glider design. Due to its likeness in shape to the Greek letter Delta, flexi-wing kites are more commonly known as delta kites. They are considered one of the easiest types to fly and, unlike others, soar with the wind rather than against it, allowing flight in very light winds.

Benjamin Franklin’s famous lightning experiment using a kite also exemplifies the way in which kites allowed scientists to conduct experiments at high altitudes.
Why are kites important?
Kites also played an important role during World Wars I and II, in which the French used them to quickly detect enemy movements, and the U.S. Navy implemented them for target practice. A Chinese general in the Han Dynasty used a kite to measure the distance into an enemy’s fortress and built a tunnel that led him to a quick victory in battle; even the ancient Egyptians used kites to lift heavy loads when building structures [3]. Despite all this, kite usage has been limited in scope, and little scientific research has been done on them.
How do kites overcome gravity?
Kites are heavier-than-air objects that overcome gravity by “catching” winds that force them upwards. As air tries to go around a kite, it travels faster above the kite and slower beneath the kite; this difference in pressure causes the kite to fly upwards since it is pushed above into the area of lower pressure.
How does a kite fly?
The forces of gravity, drag, thrust, and lift also affect the flight of a kite. Gravity is the Earth’s force pulling the kite downward, while lift is the upward force due to greater air pressure beneath a kite. The force exerted by air pressure under a kite due to wind resistance is called thrust, and drag is the downward pull resulting from a combination of the kite’s weight, shape, and angle to the ground. The lift must surpass the drag for a kite to fly, and the lift-to-drag ratio is determined by the angle of the kite to the ground – the greater the ratio, the higher and more easily the kite soars [4]. Drag can, however, be used to gain greater stability and control over a kite. The manner in which a kite flies greatly depends on the design choices made by the kite-maker; as kite flying has regained popularity in the past decade, a plethora of sophisticated kite designs have been introduced and revived.
When was the box kite invented?
However, the Box kite and other related kite designs proved better for lifting work. Hence after Hargrave from Australia invented his Box kite in the late 1800s, the Diamond kite quickly faded away from the scientific scene. In the third point above, I said 'back to recreational'.
How are diamond kites constructed?
Construction. For flimsy materials such as paper, many Diamond kites are constructed with a line around the tips of the kite spars. This forms a Diamond outline to which the sail material can be folded over and attached. My MBK kites are just fine without it, since the edges are reinforced with tape to provide resistance to stretching and tearing. It's simpler, too, and simpler is nearly always better!
What did William Eddy do to the kite?
Later, William Eddy, also from the United States, made important contributions to the use of kites for scientific purposes. Eddy experimented with tail-less Diamond kite designs, flown in trains. That is, all linked together in line. These kite trains, or stacks as they are sometimes known today were used to hoist meteorological instruments to high altitude. By 1892, all his kites featured the bowed cross-spar that enabled them to fly without tails. The 'Eddy Diamond' did a lot to make the Diamond shape kite very popular and recognizable in the Western world at that time.
What is a diamond kite?
The Diamond kite is probably the most recognized type of kite in the Western world today. For centuries it has remained popular due to its stable and reliable flying characteristics. MBK Dowel Diamond. Some people refer to Diamonds as '2 stick kites'. The two sticks are the vertical spar running from nose to tail, ...
What did Benjamin Franklin do with his kite?
In it, he described how to make a kite from a 'large, thin silk handkerchief' and 'a small cross of two light strips of cedar'.
How to make a bridle kite?
However, the more usual approach is to make a bridle by attaching a length of line to each end of the vertical spar. Or, as in the MBK Diamond, 2 points somewhere in between. The flying line is then attached to the bridle. By adjusting exactly where the flying line attaches, the kite can be made to fly nicely in a range of wind conditions.
Where is the bridle on a stunt kite?
the bridle is traditionally attached to the kite in 2 places on the vertical spar, and not necessarily at each extreme end of the spar. traditionally, the sail was paper but these days plastic, nylon or polyester is common. By the way, I'm not covering 2-line diamond stunt kites here!
