More information about the bow kite patent:
The correct name of the concept is “wing with a negative dihedron for towing a load”. As this name is not commercial the name “bow kite” was adopted due to the technology’s open arc constructions in comparison to traditional C-shape kites.
The invention enables to control the cord wise Angle of Attack throughout the entire canopy while supporting only the LE with bridles, which flattens the arc of the kite. The result shows a concave trailing edge during a flight position when viewed from above.
The result of the invention are kites that can be trimmed by the rider during flight by sheeting and letting go of the bar or by using the depower. Therefore bow kites are save in comparison to C-kites and have an improved windrange.
