Blade Sensing
Systems
Proven technology for advanced
turbine control

The current trend in wind turbine development is towards higher power and lower
cost per MW designs. Larger swept areas and rotor diameters enable increased
output but also present design challenges. Since loads increase with the cube of the
rotor diameter, greater loads can impact reliability and performance.
Moog has worked with leading blade as well as turbine and pitch control designers to
develop a modular blade sensing system. Our proven fiber-optic load measurement
system enables the fast and reliable development of individual pitch control for your
turbine, minimizing your investment and time to market.
In addition to increasing loads, the larger rotor diameter makes the turbine much
more susceptible to variations in wind speed and intensity across the swept area,
resulting in increased asymmetric loading on the turbine blades, main-shaft and
other key structural components.

Advantages
•t Proven, reliable technology for wind
turbine deployment
•t Achieve load reductions through
independent pitch control
implementation
•t Reduce structural materials and
lower parts costs
•t Proven system based on a mature
fiber optic sensing platform
•t Enables increased rotor diameter for
higher energy yield

These challenges can be overcome by designing the turbine with a Blade Sensing
System, which dynamically adjusts the pitch of each blade in real time. This enables
turbine designers and builders to balance the loading across the rotor disc, eliminate
asymmetric loading and reduce the peak loads.

•t Modified wind class for existing
machines

Moog‘s Blade Sensing Systems has been proven to deliver significant benefits in
design, manufacture and post-installation operation. The new MW class wind turbines
from initial concept designed with the Moog Blade Sensing System for individual
pitch control have experienced lower cost, higher reliability and more efficiency. The
most successful systems are fully integrated and installed in the blades and control
system during the manufacturing process.

•t Improves reliability and MTBF

•t Facilitates installation on more
complex terrains
•t Fast, simple, sensor integration into
blade production process
•t Create an accurate, reliable and cost
effective signal input

Applications
•t Load measurement system
specifically designed for wind
turbine operation
•t OEM-specific design for simple
system integration
