Abstract:
1. A method comprising: determining, by a control unit having at least one processor, a load on a rotor blade of a power generating turbine, wherein the rotor blade includes a plurality of air deflectors, wherein each of the plurality of air deflectors is configured to protrude from a surface of the rotor blade when deployed, and wherein a top surface of each of the plurality of air deflectors, when in a de-activated state, forms a portion of the surface of the rotor blade; identifying a set of one or more air deflectors to activate based on the determined load; and selectively, by the control unit, activating the set of one or more air deflectors, wherein the set of one or more air deflectors is a proper subset of the plurality of air deflectors, and wherein activating the set of one or more air deflectors includes raising an entire top surface of the set of one or more air deflectors above a surface of a remainder of the rotor blade.
