|Freedom of Tether
Angle & Kite
This kite method allows the creation of self-lifting string latticework
that accepts wind from any direction without needing to rotate.
Kite stacks, trains, and arches team multiple kites on common lines.
Typically the kite designs will only work in a specific tether
orientation, so a kite for a train does not work in an arch. A tri-swivel
and short leader along the tether allows a limited freedom for the tether
and kite to orient in any direction; in some directions the kite
interferes by briefly hanging up.
The common Flat Kite is a sparred wing that can be set on a tether through
its center of
pressure, without a bridle. Thus its free to orient to the wind in
almost every direction independent of the tether's angle. The key is for
the junction of kite and tether to act as a balanced
gimbal or ball
joint. The common method of simply tying across the kite's central spar is
often not quite free enough. KiteLab has confirmed that a well rigged Flat
Kite does indeed orient and lift properly and reliably as the tether angle
varies in almost all directions.
This is basically a realization of Dave Culp's "Flying Rope" idea. A nice
instance of this trick is a self-lifting string tripod from three fixed
anchors, with many potential uses.
