A kite is a tethered aircraft.[1] The necessary lift that makes the kite wing fly is generated when air (or in some cases water)[2][3][4] flows over and under the kite's wing, producing low pressure above the wing and high pressure below it. This deflection also generates horizontal drag along the direction of the wind. The resultant force vector from the lift and drag force components is opposed by the tension of the one or more lines or tethers.[5] The anchor point of the kite line may be static or moving (e.g., the towing of a kite by a running person, boat,[6] or vehicle).[7][8]

Stories of kites were brought to Europe by Marco Polo towards the end of the 13th century, and kites were brought back by sailors from Japan and Malaysia in the 16th and 17th centuries.[17]Although they were initially regarded as mere curiosities, but by the 18th and 19th centuries kites were being used as vehicles for scientific research.[17]

Kite traction

Kites can be used to pull people and vehicles downwind. Efficient foil-type kites such as power kites can also be used to sail upwind under the same principles as used by other sailing craft, provided that lateral forces on the ground or in the water are redirected as with the keels, center boards, wheels and ice blades of traditional sailing craft. In the last two decades several kite sailing sports have become popular, such as kite buggying, kite landboarding and kite surfing. Snow kiting has also become popular in recent years.

Kite sailing opens several possibilities not available in traditional sailing:

▪ Wind speeds are greater at higher altitudes

▪ Kites may be manoeuvered dynamically which increases the force available dramatically

▪ There is no need for mechanical structures to withstand bending forces; vehicles or hulls can be very light or dispensed with all together

The Kite Shape is usually introduced to your child in Kindergarten or First Grade. When this shape is introduced it usually...
