Problem Statement
One hindrance to the rapid evolution of new wind turbine blade designs is wind
turbine testing and certification process
Static Test
Fatigue Test
A typical 50m utility-scale blade requires:
‒ ~200 strain gages costing $35k-$50k
‒ ~20 high sensitivity accelerometers costing $12K-$30k
‒ Takes 3 weeks to setup the blade for the
test
Transducers are able to measure at discrete locations.
Prior knowledge of high strain and maximum displacement
