Kite With Self Induced Dihedral Adjustable Keel And Stabilizing Sail Turbines
US Patent:
5011099, Apr 30, 1991
Filed:
Sep 7, 1989
Appl. No.:
7/404092
Inventors:
Rudolph W. Harburg - Boulder CO
International Classification:
B64C 3106
US Classification:
244153R
Abstract:
A versatile kite having three unique features: a dihedral and double parabolic camber provided entirely by the geometry and interaction between its two spars and its flight skin, a keel that may be adjusted from zero to several inches using a simple wing nut to create a fold in the kites flight skin, and the use of light weight wind responsive sail turbines attached to the wing tips of the kite to create excellent balance and control, provide an aerial display.
