The group correctly predicted the reduced structural requirements would provide a better lift-to-weight ratio large contemporary box designs increased in weight faster than their lift, but a tetrahedral kite could be expanded with a near-constant ratio. Bell and his team, the Aerial Experiment Association, also developed biplane structures and curved wing shapes. The combined weight of his body and the rig was 208 lb (94.5 kg).Īlexander Graham Bell developed a tetrahedral kite, constructed of sticks arranged in a honeycomb of triangular sections, called cells. On 12 November 1894 he attached the rig to the ground on a long wire and lifted himself from the beach in Stanwell Park, New South Wales, reaching a height of 16 feet (4.9 m).

Lawrence Hargrave had invented his box kite in 1885, and from it he developed a man-carrying rig by stringing four of them in line. Baden-Powell's kites were sent to South Africa for use in the Boer War, but by the time they arrived the fighting was over, so they were never put into use. By the end of that year he was regularly using the kite to lift men above 100 ft (30.5 m). At Pirbright Camp on June 27, 1894, he used one of the kites to lift a man 50 feet (15.25 m) off the ground. Baden-Powell, brother of the founder of the scouting movement and soon to become President of the Aeronautical Society of Great Britain, developed his 'Levitor' kite, a hexagonal-shaped kite intended to be used by the army in order to lift a man for aerial observation or for lifting large loads such as a wireless antenna. In the 1820s British inventor George Pocock developed man-lifting kites, using his own children as guinea pigs.

To foretell whether a ship should sail, a man would be strapped to a kite having a rectangular grid framework and the subsequent flight pattern used to divine the outlook. In 1282, the European explorer Marco Polo described the Chinese techniques then current and commented on the hazards and cruelty involved. It is said that at one time there was a law in Japan against the use of man-carrying kites. He flew to the rooftop where he stole the scales, and was then lowered and escaped. His men manoeuvered him into the air on a trapeze attached to the tail of a giant kite. In one such story the Japanese thief Ishikawa Goemon (1558–1594) is said to have used a man-lifting kite to allow him to steal the golden scales from a pair of ornamental fish images which were mounted on the top of Nagoya Castle. Stories of man-carrying kites also occur in Japan, following the introduction of the kite from China around the seventh century AD. Yuan Huangtou was the only one who succeeded in flying as far as the Purple Way, and there he came to earth.' The Purple Way, a road, was 2.5 km from the approximately 33 metre tall Golden Phoenix Tower. 'Gao Yang made Yuan Huangtou and other prisoners take off from the Tower of the Phoenix attached to paper owls. The (1044) Zizhi Tongjian records that in 559, all the condemned kite airmen died except for Eastern Wei prince Yuan Huangtou. 550-559), executed prisoners by ordering them to 'fly' using bamboo mats. The Book of Sui, dating from 636 A.D, records that the tyrant Gao Yang, Emperor Wenxuan of Northern Qi (r. Man-carrying kites were used in ancient China, for both civil and military purposes and sometimes enforced as a punishment. In the 21st century man-lifting kites are often used in kitesurfing, where brief launches can be followed by safe water landings and parasailing, where kites are towed behind a vehicle. Recreational man-lifting kites gradually gained popularity through the latter half of the 20th century, branching into multiple sports. Interest in their development declined with the advent of powered flight at the beginning of the 20th century. Historically, man-lifting kites have been used chiefly for reconnaissance. Lawrence Hargrave (seated) with his man-lifting kites in Stanwell Park, 1894.Ī man-lifting kite is a kite designed to lift a person from the ground. Man-lifter War Kite designed by Samuel Franklin Cody (1867–1913). Kite designed to lift a person from the ground Roald Amundsen, the polar explorer, is lifted from the ground using a man-lifting kite during tests in 1909.
