WIND TURBINE ROTOR BLADE WITH FAIL-SAFE AIR BRAKE FLAPS
A wind turbine blade includes an air brake flap flush mounted within a recess in the suction side of the blade. The air brake flap is actuatable from a retracted position within the recess to an open position wherein the air brake flap extends transversely or vertically from the suction side. A fail...

| description | A wind turbine blade includes an air brake flap flush mounted within a recess in the suction side of the blade. The air brake flap is actuatable from a retracted position within the recess to an open position wherein the air brake flap extends transversely or vertically from the suction side. A fail-safe actuator is operatively coupled to the air brake flap and is configured to hold the air brake flap at the retracted position in a powered state of the actuator and to release the air brake flap to the open position upon loss of power to the actuator. |
