Abstract
The lengths and/or chords and/or pitches of wind turbine or propeller blades are individually established, so that a first blade can have a length/chord/pitch that is different at a given time to the length/chord/pitch of a second blade to optimize performance and/or to equalize stresses on the system.
Claims20
A wind turbine, comprising:
- a rotor;
- a plurality of blades coupled to the rotor;
- an actuator coupled to each blade and capable of altering a pitch of said blade;
- and
- a controller coupled to said actuators for independently controlling said pitch of each blade in response to signals indicating a speed of wind approaching each blade.

A wind turbine, comprising:
- a rotor;
- a plurality of blades coupled to the rotor;
- an actuator coupled to each blade and capable of altering a pitch of said blade;
- a controller coupled to said actuators for independently controlling said pitch of each blade in response to signals indicating a speed of wind approaching each blade and a fluid pressure on each blade.
1 more element
A wind turbine, comprising:
- a rotor;
- a plurality of blades coupled to the rotor;
- an actuator coupled to each blade and capable of altering a respective pitch of the respective blade;
- a controller that independently controls, via the actuators, a respective pitch of each blade in response to fluid pressure on at least one blade.
1 more element
A wind turbine, comprising:
- a rotor;
- a plurality of blades coupled to the rotor;
- an actuator coupled to each blade and capable of altering a pitch of said blade;
- a controller coupled to said actuators for independently controlling said pitch of each blade to thereby reduce load imbalances on the blades.
