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 defining an axis of rotation, the first blade defining a first pitch at a first time, the second blade defining a second pitch at the first time, the first and second pitches not being equal and at least one of the pitches being established by a pressure signal from at least one pressure sensor. 2. The assembly of claim 1, wherein the pitches are based on respective positions of the blades. 3. The assembly of claim 1, comprising an actuator coupled to at leas...
