    Abstract: A fluid flow turbine blade assembly for a turbine rotor includes a blade and a deflector extending spanwise along at least a portion of the blade. At least a portion of an upstream surface of the deflector, along at least a portion of a span of the deflector, has a concave shape in a chordwise direction such that at least a portion of a chord line between leading and trailing edges of the deflector is disposed outside a profile defined between the upstream surface and a downstream surface of the deflector. The deflector has a substantially uniform thickness or a chord-wise varying thickness between the upstream surface and the downstream surface. The deflector alters fluid flow over the blade so as to increase the blade's contribution to global torque generated by the assembly so that, with the deflector's torque contribution, the global torque of the assembly is greater than the global torque that would be generated by the blade alone without the benefit of the deflector.

    Abstract: A rotor blade assembly for mitigating stall-induced vibrations of a wind turbine during standstill includes at least one protrusion secured to the leading-edge of a rotor blade and defining an extended leading edge. The protrusion(s) wraps around a portion of the rotor blade from the suction side to the pressure side of the rotor blade. The protrusion(s) has a root-side face and a tip-side face disposed opposite thereof. The root-side face is arranged at an angle relative to a chordwise reference line. The angle is greater than zero degrees and less than or equal to 45 degrees with respect to the chordwise reference line. The protrusion(s) is configured to affect a chordwise airflow and thereby mitigate a stall-induced vibration.

    Abstract: The present invention relates to a leading edge protection for a wind turbine blade, wherein a leading edge axis of the leading edge protection is configured to be fitted on at least part of a leading edge of a wind turbine blade and the leading edge protection is configured to extend between the leading edge and a first edge downstream a first side of the wind turbine blade as well as between the leading edge and a second edge downstream a second side of the wind turbine blade, wherein the leading edge protection comprises a first part and wherein the first edge is configured to be non-parallel with the leading edge of the wind turbine blade along the first part of the leading edge protection. The present invention further relates to a wind turbine blade comprising the leading edge protection and a wind turbine comprising the wind turbine blade. Finally, the present invention relates to a method for protecting a leading edge of a wind turbine blade arranged on a wind turbine and a leading edge protection obtainable by that method.

    Abstract: A fairing for a modular blade of a wind turbine generator, comprising including a joining zone disposed between two consecutive modules of the modular blade. The fairing is comprised of different components; the suction side fairing, the pressure side fairing and auxiliary components, such as tabs to facilitate the joining of the components. The leading edge fairing and the trailing edge fairing are constituted of an elastomeric material, preferably silicone, supported in a rigid glass fibre framework in order to absorb the warping experienced by the blade during the operation thereof. The attachment elements employed to join the fairings together and to the setbacks of the blade shell are rivets or similar. All the fairings incorporate the metal elements necessary to be equipotentially bonded, being linked to the lighting down-drop.
