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 box is made rigid with diagonal crossed struts. There are two sails, or ribbons, whose width is about a quarter of the length of the box. The ribbons wrap around the ends of the box, leaving the ends and middle of the kite open. In flight, one strut is the bottom, and the bridle is tied between the top and bottom of this strut. The dihedrals of the sails help stability.

  • 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 box is made rigid with diagonal crossed struts. There are two sails, or ribbons, whose width is about a quarter of the length of the box. The ribbons wrap around the ends of the box, leaving the ends and middle of the kite open. In flight, one strut is the bottom, and the bridle is tied between the top and bottom of this strut. The dihedrals of the sails help stability. The box kite was invented in 1893 by Lawrence Hargrave, an Englishman who emigrated to Australia, as part of his attempt to develop a manned flying machine. Hargrave linked several of his box kites (Hargrave cells) together, creating sufficient lift for him to fly some 16 ft (4.9 m) off the ground. A winged development of this kite is known as the Cody kite following its development by Samuel Franklin Cody. Military uses also involved a kite/radio transmitter combination issued to pilots during World War II for use in liferafts. Large box kites are constructed as cellular kites. Rather than one box, there are many, each with its own set of sails. Most of the altitude records for kite flying are held by large box kites, with Dacron sails, flown with Spectra cable. Before Dacron, Spectra, and Kevlar were available, high performance box kites used oiled silk, linen or hemp sails, and were flown with steel cable. Silk, linen and hemp were used because they could be spun finer than cotton and stretched relatively little when wet. Steel had the highest available strength for its weight. (en)

  • Uma pipa caixa é uma pipa de alta performance capaz de produzir uma sustentação relativamente alta. O desenho típico possui quatro estruturas paralelas. A "caixa" é tornada rígida por estruturas cruzadas na diagonal. A pipa caixa foi inventada em 1893 por Lawrence Hargrave, um inglês que emigrou para a Austrália, como parte de sua tentativa de desenvolver uma máquina voadora tripulada. Hargrave interligou várias de suas pipas (células de Hargrave), que juntas produziram sustentação suficiente para erguê-lo quase 5 metros acima do solo. Um desenvolvimento com asas dessa pipa ficou conhecido como Cody kite (pipa de Cody) por ter sido desenvolvida por Samuel Franklin Cody. Usos militares também envolveram uma combinação pipa/rádio transmissor usadas por pilotos em missões "salva-vidas" durante a Segunda Guerra Mundial. (pt)
