Abstract
A vertical turbine comprising a blade control mechanism including a sun gear engaging a plurality of planetary gears each coupled to blade assemblies. The sun gear has at least half circumference of its teeth removed, as the turbine receives maximum downstream torque in the circumference with teeth and it leaves blades free to rotate in the circumference without teeth for minimum upstream drag. The turbine converts the rotational blades into parallel movement and unidirectional propulsion with minimum turbulence.
Claims14
A vertical turbine, comprising:
- a shaft;
- a rotor adapted to rotate on the shaft;
- a blade control mechanism that includes:
- a sun gear adapted to rotate on the shaft, wherein the sun gear has teeth removed on part of the circumference;
- a direction control pulley secured to the sun gear;
- a plurality of blade assemblies rotatably on the rotor, each blade assembly including:
- a planetary gear;
- and
- a blade coupled to the planetary gear, wherein the planetary gears engage the sun gear teeth and disengage from the sun gear on part of the circumference without teeth.
