Autorotation (fixed-wing Aircraft) - Autorotation in Kites and Gliders

Autorotation in Kites and Gliders

1. Magnus effect rotating kites that have the rotation axis bluntly normal to the stream direction use autorotation; a net lift is possible that lifts the kite and payload to altitude. The Rotoplane, the UFO rotating kite, and the Skybow rotating ribbon arch kite use the Magnus effect resulting from the autorotating wing with rotation axis normal to the stream.
2. Some kites are equipped with autorotation wings.
3. Again, a third kind of autorotation occurs in self-rotating bols, rotating parachutes, or rotating helical objects sometimes used as kite tails or kite-line laundry. This kind of autorotation drives wind and water propeller-type turbines, sometimes used to generate electricity.
4. Unlocked engine-off aircraft propellers may autorotate. Such autorotation is being explored for generating electricity to recharge flight-driving batteries.
