     RECAPTURE


     LOST ENERGY PRODUCTION WITH SPECIALTY ADD-ONS.


     VORTEX GENERATORS &
     GURNEY FLAPS

     Because wind turbine blades are exposed to ex-
     treme loads, they are designed on a compromise
     between aerodynamics and structural stability.
     Specialty add-ons can increase annual energy pro-
     duction (AEP) by up to 6%.



     STALL STRIPS                                               VG STRIPS

     Reduce stress cracks caused by edgewise vibration.



     SERRATIONS

     Decrease the sound of a turbine in operation.



     LEADING EDGE PROTECTION


     Turbine blades all eventually have leading edge
     erosion if untreated, which can cause a performance
     drop of 4% and consequent loss of revenue.                SERRATIONS
