A box kite is a high-performance kite, noted for developing relatively high lift; it is a type within the family of cellular kites. The typical design has four parallel struts. The typical design has four parallel struts.
In general, the larger the surface area, the more power the kite has. Kite power is also directly linked to speed, and smaller kites can be flown faster in stronger winds. The kite size—wind speed curve tapers off, so going to a larger kite to reach lower wind ranges becomes futile at a wind speed of around eight knots.
For long voyages, the kite rig must be more autonomously controlled. Due to the lifting power of kites, they are often used with hydrofoils. [2] Points of sail (with a kite buggy) Current kite rigs can be sailed within 50 degrees of the wind. [1] Placing turbines in the boat's hull can let the kite power generate electricity on board. [3]
The kites were ordinary two-spar Eddy style kites with a height of about five feet. The sail was sky blue with the profile of a Japanese Zero or German aircraft painted in black. Attached at the lower end of the vertical spar is a small rudder, much like a boat's rudder. The rudder is controlled by two kite lines, which are also used to fly the ...
These kites are flown using 2, 4 or 5 control lines and a bar. (See also: kite control systems) A LEI is a great kite for water use because the inflated bladders cause it to float on the water surface. A LEI can sit on the water for an indefinite time and still be relaunched because, unlike a foil kite, there are no chambers that can fill with ...
The Peel was a popular kite traction kite in the early to mid-1990s and continued to sell into the late 1990s and was sold in sizes up to 10 m 2. The Peel was also a two-line kite flown in the same style as the Flexifoil. The next evolution on the foil kites for traction activities was the development of the 4-line foil kite.
The lift generated by the kite and other flying characteristics are affected by the kite's angle of attack, which is set by the bridle; the arrangement of lines which terminate the main kite lines and attach to a number of points across the kite's surface. Power kites having 4 or 5 lines come in two variants, fixed bridle and depowerable.
The SkySails propulsion system consists of a large foil kite, an electronic control system for the kite, and an automatic system to retract the kite. The kite, while 1–2 orders of magnitude larger, bears similarities to the arc kites used in kitesurfing. However, the kite is an inflatable rather than a ram-air kite.
