Abstract
Predictively adjusting the pitch of blades and/or sections of a blade based on fluid velocity measurements. In one embodiment, the measurements are obtained of an upstream portion of a fluid flow using a laser Doppler velocimeter. The pitch of the blade(s) and/or blade section(s) are then adjusted to achieve a desired amount of lift or to create a stall-configuration as can be useful for conditions in which an excessive fluid velocity is detected.
