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.
Claims20
An automated system for achieving a desired amount of lift in a blade comprising:
- providing a pitch-adjustable blade;
- providing a laser Doppler velocimeter;
- measuring a velocity of an up-stream fluid with the laser Doppler velocimeter;
- and
- adjusting a pitch of the blade to achieve a desired amount of lift based on the measured up-stream fluid velocity.
