Abstract:
1. A wind turbine comprising: a wind turbine blade disposed on the wind turbine, the blade being configured to rotate about an axis upon an impact of a wind flow on the blade; at least one load sensor disposed within the surface of the blade, the at least one load sensor configured to measure local loading on the blade due to local wind inflow sensed at the at least one load sensor; and at least one active flow modification device disposed on the blade, the at least one active flow modification device configured to modify the wind flow proximate to the blade in response to a local twist angle determined at each load sensor location, and wherein the at least one active flow modification device is configured to receive active flow modification instructions based on the at least one sensor local loading measurements, and further wherein the at least one load sensor and the wind turbine blade are constructed of the same reinforcing fiber material.
