Abstract
Devices, such as aerodynamic kites used in kiteboarding (also known as kitesurfing), handheld aerodynamic wings used in wing foiling and wing surfing, and paddles used in paddleboarding, for generating a force for powering a user on an appropriately configured vehicle, such as a kiteboard, kitesurfing foilboard, hydrofoil board, surfboard, wing board, wing foil board, stand up paddleboard, stand up paddleboard with hydrofoil, roller skates, rollerblades, skateboards, snowboards, skis, or ice skates, to traverse across a body of water, sand, earth, paved area, snow, or ice, are provided with a thrust generating device (e.g., an electric ducted fan system) to assist in generating said force.
Claims37
An aerodynamic kite for generating tractive force for powering a user on a variety of vehicles, comprising
- a leading edge, a trailing edge, a right side edge, a left side edge, a top surface, a bottom surface, and a canopy extending between the leading edge and the trailing edge,
- means on the kite for attaching control lines to the kite, and
- powered propulsion means mounted to the kite for producing thrust,
- the powered propulsion means comprising a first electric ducted fan system mounted to the kite,
- the kite having a leading edge side and a trailing edge side, and
- the kite further including
- a hood scoop mounted over a portion of the top surface of the kite, the hood scoop having an opening at its front end portion to allow air to enter into the hood scoop from the leading edge side of the kite and having an opening at its rear end portion to allow air to exit from the hood scoop towards the trailing edge side of the kite, wherein the electric ducted fan system is positioned within the hood scoop for propelling air from the opening at the rear end portion of the hood scoop.
