Watercraft device with hydrofoil and electric propeller system
A hydrofoiling watercraft is disclosed that includes a board having a top surface for supporting a user and a bottom surface. Extending from the top surface of the board is a handlebar. Extending from the bottom surface of the board is a hydrofoil including a strut and a hydrofoil wing. A propulsion system is attached to the hydrofoil.
1 . A hydrofoil device comprising:
a board having a top surface and a bottom surface;
a hydrofoil including a strut connected to the bottom surface of the board;
a propulsion system coupled to the hydrofoil;
at least one of an accelerometer, gyroscope, and inertial measurement unit configured to output at least one of speed, position, and orientation data of the board; and
a computerized control system configured to modulate power provided to the propulsion system based on the at least one of speed, position, and orientation data.
2 . The hydrofoil device of claim 1 , wherein the computerized control system modulates the power provided to the propulsion system to stabilize the board.
3 . The hydrofoil device of claim 2 , wherein the computerized control system is configured to receive a request for stabilization from a user, wherein the computerized control system is configured to modulate the power provided to the propulsion system to stabilize the board responsive to the request.
4 . The hydrofoil device of claim 1 , wherein the computerized control system modulates the power provided to the propulsion system to adjust a ride height of the board.
5 . The hydrofoil device of claim 1 , wherein the computerized control system is configured to receive a control signal from a throttle controller to operate the hydrofoil device, the computerized control system further configured to adjust the operation of the propulsion system based at least in part on the control signal.
6 . The hydrofoil device of claim 1 , wherein the propulsion system includes a propulsion pod and a propeller.
7 . The hydrofoil device of claim 1 , further comprising a battery, wherein the computerized control system is configured to modulate power provided from the battery to the propulsion system.
8 . The hydrofoil device of claim 1 , wherein the computerized control system is configured to determine at least one of when the board has tipped over, is tipping over, and has collided with an object based at least in part on the output of the at least one of an accelerometer, gyroscope, and inertial measurement unit.
9 . The hydrofoil device of claim 1 , wherein the hydrofoil includes a fuselage coupled to the strut, a forward wing, and an aft wing.
10 . The hydrofoil device of claim 1 , wherein the hydrofoil has at least one movable control surface and the computerized control system is further configured to adjust a position of the at least one movable control surface of the hydrofoil.
11 . The hydrofoil device of claim 10 , wherein the computerized control system is configured to receive a control signal from a throttle controller to operate the hydrofoil device, wherein the computerized control system is configured to adjust the position of the movable control surface based at least in part on the control signal.
12 . The hydrofoil device of claim 10 , wherein the hydrofoil includes at least one hydrofoil wing and the at least one movable control surface is a surface of the at least one hydrofoil wing.
13 . The hydrofoil device of claim 10 , wherein the at least one movable control surface is a foil flap.
