Abstract

Abstract This invention relates to a winged rotary kite which has its lift power generated by wind driven rotors and is adaptable for use under normal conditions without the need for a tail, the kite comprising a finlike body to provide directional stability; a member attached to the body for connecting a flexible towline thereto; a wing mounted on and bisected by the body; a pair of axles connected to the distal ends of the wing and extending upwardly therefrom; and a rotor rotatably mounted on each axle, each rotor being spaced a distance above the wing, whereby the rotor as it passes over the wing is maintained in turbulent air rather than in direct airflow thus obtaining less drag on the rotor as it passes over the wing, as compared to the drag on the rotor when it is not over the wing, and by this arrangement causing the turbulent air to be dispersed inwardly from below each rotor toward the fuselage where it is then dumped rewardly, enabling the kite to maintain pitch and vertical stability.

Claims Analysis

Total Claims: 8
Claim 1
Independent Claim 69 words
A winged rotor kite comprising: a tailless fuselage comprising an elongated, thin, flat member; a wing mounted on and bisected by said fuselage; a pair of rotors, each rotor including a hub; means for mounting a rotor at each outer end of said wing, said hub of each rotor spaced above and in noncontacting relation to said wing; and means connected to said fuselage for attaching a towline thereto.
Claim 2
Dependent Claim 69 words
A winged rotor kite comprising: a tailless fuselage comprising an elongated, thin, flat member; a wing mounted on and bisected by said fuselage; a pair of rotors, each rotor including a hub; means for mounting a rotor at each outer end of said wing, said hub of each rotor spaced above and in noncontacting relation to said wing; and means connected to said fuselage for attaching a towline thereto.
Claim 3
Dependent Claim 17 words
A winged rotor kite as defined in claim 1, wherein said fuselage has a substantially triangular shape.
Claim 4
Dependent Claim 18 words
A winged rotor kite as defined in claim 2 wherein said wing has s slightly positive dihedral angle.
Claim 5
Dependent Claim 27 words
A winged rotor kite as defined in claim 3 wherein each of said rotors include a plurality of blades, each of said blades having a slight pitch.
Claim 6
Dependent Claim 23 words
A winged rotor kite as defined in claim 4 wherein said blades connect to said hub to form a slightly positive dihedral angle.
Claim 7
Dependent Claim 36 words
