Kite Applications
Different types of flying kites (such as water kites, bi-media kites, fluid kites, gas kites, kytoons, Paravane (water kite), paravanes, soil kites, solid kites, and plasma kites) have niche applications. In nature, some animals, such as spiders, also make use of Ballooning (spider), kiting. Aerial photography File:PicEddyKite.jpg, William Abner Eddy patented a kite.

Kytoon
A kytoon or kite balloon is a tethered aircraft which obtains some of its lift dynamically as a heavier-than-air kite and the rest aerostatically as a lighter-than-air balloon. The word is a portmanteau of kite and balloon. The primary advantage of a kytoon is that it remains in a reasonably stable position above the tether point, irrespective of the strength of wind, whereas ordinary balloons and kites are less stable. The kytoon has been used for many purposes, both civil and military. History In 1919, a handbook was published giving extensive details to support the kite balloon crafts being used in the military. Described is the first kite balloon made in 1893 by Captains Parseval and Sigsfeld at the Berlin works of the Prussian Balloon Battalion; theirs was the "predecessor of the ''Drachen'' balloon." "This was the first real kite balloon flying like a kite with a fairly constant angle and direction relative to the wind and remained practically unchanged until the beginni ...

MS Beluga Skysails
MS ''Onego Deusto'' (christened ''Beluga SkySails'') is a commercial Containerization, container cargo ship. It is the world's first ship partially powered by a computer-controlled kite rig, called the SkySails system. It consists of a kite similar to a huge paraglider of up to area. Kite power The kite has an area of and reduces fuel consumption by 15–20% on average; it was set to be upgraded to in order to increase fuel savings by about 30%. Stephan Wrage, managing director of SkySails GmbH – which installed the kite – announced: "During the next few months we will finally be able to prove that our technology works in practice and significantly reduces fuel consumption and emissions." Verena Frank, project manager at Beluga Shipping GmbH, SkySails GmbH's partner, further stated that "the project's core concept was using wind energy as auxiliary propulsion power and using wind as a free of charge energy". This kite is connected to the ship by a cable, and controlled by ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ray Bethell
Ray Bethell (March 1, 1928 - December 18, 2018) was a professional kite flyer who resided in Vancouver, British Columbia, Canada. He holds multiple endurance world records related to simultaneously flying three stunt kites, one from each hand and one from his hips. Using the same technique he can fly multiple stacks of kites (up to 39 kites in total). Bethell has travelled extensively since 1991 displaying his prowess at International Kite Festivals. He was the subject of a documentary short film by Matt Nie of the Vancouver Film School"Good Stuff" which won first place at the 2005 TriBeCa Film Festival in New York City. In October 2006, a commemorative bench was unveiled at Ray's home flying spot, Vanier Park in Vancouver Vancouver is a major city in Western Canada, located in the Lower Mainland region of British Columbia.

Sport Kite
A sport kite, also commonly known as a stunt kite, is a type of multiline kite that can be maneuvered in the air. A related kite, also controllable and used for recreation, but capable of generating a significant amount of pull and used for providing movement, is the power kite. Configuration One common configuration for a sport kite is a roughly triangular "delta" shape based on the Rogallo wing, with two lines for control. Another common configuration is a W-shaped panel based on the Kite types, Hadzicki wing, with four lines for control. These kites are normally constructed from lightweight ripstop nylon or ripstop polyester with spars made from carbon fiber tubing. The flying lines are made from braided ultra-high-molecular-weight polyethylene, which is light, does not stretch under tension and stays slippery even when wrapped many times. Dual-line sport kites are controlled by the pilot adding and releasing tension on the right and left lines. A pilot may pull on the righ ...

Peter Powell (kite Maker)
Peter Trevor Powell (29 June 1932 – 3 January 2016)''The Times'' Obituary - Peter Powell, 8 February 2016. p48 was a British kite maker who developed a steerable kite in 1972, using dual lines. The kite that made him famous is known as the "Peter Powell Stunter". It became an international bestselling kite in 1976. Very early on, Powell's kites had spars made of ramin (''Gonystylus'') which were later replaced with aluminium tubing and, later still, by glass fibre spars. Originally they all came with black plastic sails, though later blue, red and yellow sails became available. The kites came with a long, hollow polyethylene tail that was inflated by the wind. The tail added stability as well as looking good when performing stunts. Early life He was born in Gloucester, England. at SO Glos onl ...

Hang Gliding
Hang gliding is an air sports, air sport or recreational activity in which a pilot flies a light, non-motorised, fixed-wing aircraft, fixed-wing heavier-than-air aircraft called a hang glider. Most modern hang gliders are made of an aluminium alloy or Composite material, composite frame covered with synthetic sailcloth to form a wing. Typically the pilot is in a harness suspended from the airframe, and controls the aircraft by shifting body weight in opposition to a control frame. Early hang gliders had a low lift-to-drag ratio, so pilots were restricted to gliding down small hills. By the 1980s this ratio significantly improved, and since then pilots have been able to Lift (soaring), soar for hours, gain thousands of meters of altitude in thermal updrafts, perform aerobatics, and glide cross-country for hundreds of kilometers. The Federation Aeronautique Internationale and national airspace governing organisations control some regulatory aspects of hang gliding. Obtaining the sa ...

Snow Kiting
Snowkiting or kite skiing is an outdoor winter sport where people use kite power to glide on snow or ice. The skier uses a kite to give them power over large jumps. The sport is similar to water-based kiteboarding, but with the footwear used in snowboarding or skiing. The principles of using the kite are the same, but in different terrain. In the early days of snowkiting, foil kites were the most common type; nowadays many kiteboarders use inflatable kites. However, since 2013, newly developed racing foil kites seem to dominate speed races and expedition races, like Red Bull Ragnarok (held on the Norwegian Hardangervidda plateau) and the Vake mini-expedition race (held at Norway's most northern Varanger peninsula). Snowkiting differs from other alpine sports in that it is possible for the snowkiter to travel uphill and downhill with any wind direction. Like kiteboarding, snowkiting can be very hazardous and should be learned and practiced with care. Snowkiting has become more po ...

Kite Landboarding
Kite landboarding, also known as land kiteboarding or flyboarding, is based on the sport of kitesurfing, where a rider on a surf-style board is pulled over water by a kite. Kite landboarding involves the use of a mountain board or landboard, which is essentially an oversized skateboard with large pneumatic wheels and foot-straps. Kite landboarding is a growing sport, and there are several competitions. Kite landboarding is attracting growing publicity although it is not yet as popular or as well known as kitesurfing. Technique Typically, kite landboarding takes place in large open areas where the wind is constant and there are no obstructions such as trees or people. Large hard-packed sandy beaches are typical landboarding locations because of the large space available and wind conditions. The rider starts off by getting the kite into a neutral position overhead. Once strapped onto the board, the rider can orient the kite such that it pulls the rider across the ground. This is do ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Kite Boarding
Kiteboarding or kitesurfing is a sport that involves using wind power with a large power kite to pull a rider across a water, land, snow, sand, or other surface. It combines the aspects of paragliding, surfing, windsurfing, skateboarding, snowboarding, and wakeboarding. Kiteboarding is among the less expensive and more convenient sailing sports. After some concepts and designs that emerged in the late 1970s and early 1980s were successfully tested, the sport received a wider audience in the late 1990s and became mainstream at the turn of the century. It has freestyle, wave-riding, and racing competitions. The sport held the speed sailing record, reaching before being eclipsed by the Vestas Sailrocket. Worldwide, there are 1.5 million kitesurfers, while the industry sells around 100,000 to 150,000 kites per year. Most power kites are leading-edge inflatable kites or foil kites attached by about of flying lines to a control bar and a harness. The kitesurfer rides o ...

Glow Stick
A glow stick, also known as a light stick, chem light, light wand, light rod, and rave light, is a self-contained, short-term light-source. It consists of a translucent plastic tube containing isolated substances that, when combined, make light through chemiluminescence. The light cannot be turned off and can be used only once. The used tube is then thrown away. Glow sticks are often used for recreation, such as for events, camping, outdoor exploration, and concerts. Glow sticks are also used for light in military and emergency services applications. Industrial uses include marine, transportation, and mining. History Bis(2,4,5-trichloro-6-(pentyloxycarbonyl)phenyl)oxalate, trademarked "Cyalume", was invented in 1971 by Michael M. Rauhut, of American Cyanamid, based on work by Edwin A. Chandross and David Iba Sr. of Bell Labs. Other early work on chemiluminescence was carried out at the same time, by researchers under Herbert Richter at China Lake Naval Weapons Center. Sever ...

Sailing Ship
A sailing ship is a sea-going vessel that uses sails mounted on Mast (sailing), masts to harness the power of wind and propel the vessel. There is a variety of sail plans that propel sailing ships, employing Square rig, square-rigged or Fore-and-aft rig, fore-and-aft sails. Some ships carry square sails on each mast—the brig and full-rigged ship, said to be "ship-rigged" when there are three or more masts. Others carry only fore-and-aft sails on each mast, for instance some schooners. Still others employ a combination of square and fore-and-aft sails, including the barque, barquentine, and brigantine. Early sailing ships were used for river and coastal waters in Ancient Egypt and the Mediterranean. The Austronesian peoples developed maritime technologies that included the fore-and-aft crab-claw sail and with catamaran and outrigger boat, outrigger hull configurations, which enabled the Austronesian expansion into the islands of the Indo-Pacific. This expansion originated in Ta ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
