Abstract
A spinning horizontal axis wind turbine is disclosed. The blades of the wind turbine are configured to allow the blades to simultaneously rotate in a vertical axis and a horizontal axis when acted upon by an external force such as a wind current. The tip of each blade travels along a helical “figure 8” pattern as the blade rotates through a complete cycle, moving from nearly vertical to nearly horizontal in a complete cycle.
Claims18
A wind turbine comprising:
- a mast;
- a mast gear connected to an end of the mast
- a blade axle connected to the mast gear;
- and
- a first turbine blade and a second turbine blade connected to the blade axle, wherein a longitudinal axis of the first turbine blade and the second turbine blade are substantially perpendicular to the blade axle and configured to rotate about a vertical axis of the mast and a horizontal axis of the mast when acted on by an external force.
2 more elements
A wind turbine comprising:
- a mast;
- a mast gear connected to an end of the mast;
- a drive shaft configured to rotate about a drive shaft axis;
- at least one blade axle connected to an end of the drive shaft, wherein the blade axle is configured to rotate about a blade axle axis that is perpendicular to the drive shaft axis;
- at least one blade gear connected to an end of the at least one blade axle, wherein the blade gear is configured to engage the mast gear;
- and
- a first turbine blade and a second turbine blade connected to the at least one blade axle, wherein a longitudinal axis of the first turbine blade and the second turbine blade are substantially perpendicular to the at least one blade axle and configured to rotate about a vertical axis of the mast and a horizontal axis of the mast when acted on by an external force.
4 more elements
A wind turbine comprising:
- a mast;
- a mast gear connected to an end of the mast
- a drive shaft connected to the mast gear, wherein the drive shaft is configured to transmit power from the blades via the mast gear to perform work;
- at least one blade axle connected to the mast gear, wherein the blade axle is configured to rotate about a blade axle axis that is perpendicular to a drive shaft axis;
- and
- a first turbine blade and a second turbine blade connected to the at least one blade axle, wherein a longitudinal axis of the first turbine blade and the second turbine blade are substantially perpendicular to the at least one blade axle, wherein when the at least one of the first turbine blade or the second turbine blade is acted upon by an external force, the at least one of the first turbine blade or the second turbine blade rotates about the blade axle and the drive shaft axis, causing a tip of the at least one of the first turbine blade or the second blade to move in a figure eight path during a rotational cycle.
