The kite experiment is a scientific experiment in which a kite with a pointed conductive wire attached to its apex is flown near thunder clouds to collect static electricity from the air and conduct it down the wet kite string to the ground. The experiment was first proposed in 1752 by Benjamin Franklin, who reportedly conducted the experiment ...
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.
A kite is a tethered heavier-than-air or lighter-than-air craft with wing surfaces that react against the air to create lift and drag forces. [ 2 ] A kite consists of wings, tethers and anchors. Kites often have a bridle and tail to guide the face of the kite so the wind can lift it. [ 3 ]
The kite is a quadrilateral whose four interior angles are 72, 72, 72, and 144 degrees. The kite may be bisected along its axis of symmetry to form a pair of acute Robinson triangles (with angles of 36, 72 and 72 degrees). The dart is a non-convex quadrilateral whose four interior angles are 36, 72, 36, and 216 degrees. The dart may be bisected ...
A man-lifting kite is a kite designed to lift a person from the ground. Historically, man-lifting kites have been used chiefly for reconnaissance. Interest in their development declined with the advent of powered flight at the beginning of the 20th century. Recreational man-lifting kites gradually gained popularity through the latter half of ...
Fighter kite. Fighter kites are kites used for the sport of kite fighting. Traditionally, most are small, unstable single-line flat kites where line tension alone is used for control, at least part of which is manja, typically glass-coated cotton strands, to cut down the line of others.
The Rogallo wing is a flexible type of wing. In 1948, Francis Rogallo, a NASA engineer, and his wife Gertrude Rogallo, invented a self-inflating flexible wing they called the Parawing, also known after them as the "Rogallo Wing" and flexible wing. [1] NASA considered Rogallo's flexible wing as an alternative recovery system for the Mercury and ...
It is unknown whether the ancient Egyptians had kites, but a team led by Maureen Clemmons and Mory Gharib raised a 5,900-pound, 15-foot (4.6 m) obelisk into vertical position with a kite, a system of pulleys, and a support frame. [32] Maureen Clemmons developed the idea that the ancient Egyptians used kites for work. [32] [33]
