Box kite coloring pages

Nov 17 2019

Most of the altitude records for kite flying are held by large box kites, with Dacron sails, flown with Spectra cable. However in 2014 Robert Moore and a team of kite experts flew a 12 sq metre DT delta to 16,009 ft above their launch point. The location of the flights was near Cobar in Western NSW, Australia. While this was primarily a triangular winged delta kite, it has a triangular box centre cell for additional stability. . Future attempts on either the single kite record or multiple kite record (trained), may use Hargrave box kites or a variant. 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. After Hargrave invented the box kite, weather stations from around the world saw the potential for his design. Blue hill observatory and the German weather station at Lindenberg used kites routinely until weather balloons took over in the 1920s and 1930s.
