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.
1. A wind turbine blade assembly comprising: at least first and second blades coupled to a rotor, the first blade defining a first pitch at a first time, the second blade defining a second pitch at the first time, at least one of the pitches being established by a pressure signal from at least one pressure sensor disposed on at least one blade to provide the pressure signal;at least one controller receiving input from the pressure sensor;at least one actuator comprising at least one motor coupled to at least the first blade and controlled by the at least...
