초록

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.

대표
청구항

1. A wind turbine blade assembly comprising: at least first and second blades coupled to a rotatable rotor defining an axis of rotation, the first blade having a first blade tip being a first distance from the axis of rotation at a first time, the second blade having a second blade tip being a second distance from the axis of rotation at the first time, the first and second distances not being equal, wherein the distances are based on respective angular positions of the blades relative to the rotor independently of forces on the blades, the first distanc...
