Abstract: A wind turbine blade has a suction side shell member and a pressure side shell member. The shell members are joined along a leading and trailing edge from a root to a tip of the blade and defining an internal cavity of the blade. A pressure sensor is configured on at least one of the suction or pressure side shell members. The pressure sensor further includes a body mounted to an inner surface of the respective shell member within the internal cavity. A sensing element has a first side exposed to external air pressure through a passage in the respective shell member, and an opposite second side exposed to a reference pressure. Control circuitry within the body generates a variable output signal as a function of a pressure differential between the external air pressure and reference pressure experienced by the sensing element.

Abstract: A wind turbine blade (112) is situated on a wind turbine (100). The wind turbine blade (112) includes a tip portion (122) and an obstruction removal system (200). The tip 212 portion (122) comprises an end wall which defines an opening. The obstruction removal system (200) is positioned with respect to the blade (112) so as to remove obstructions from the opening.
