Abstract

<p>In order to investigate the feasibility of high-altitude flight of a kite, the static force balance on a mooring cable and a kite is considered. The kite is treated as a single-point mass and the mooring cable is divided to multiple fragments with mass. First, the kite-flying experiment is carried out to validate the analytical technique. The kite flies at a height of 94m and the measured tensile force is about 12N. Next, the flight at height of 5km is investigated analytically. Normally available polyethylene line can withstand the required load and the flight is shown possible. Moreover, it is shown that the 7km flight is also possible by using ultra-high-strength polyethylene fiber. For a higher-height flight it is not possible in the analyses made here.</p>
