摘要： By means of a simple structure, lightning resistance is improved without increasing the level of fluid noise due to a lightning discharge member provided on a surface of a wind turbine blade. A wind turbine rotor blade lightning discharger, in which a diverter strip serving as a lightning discharge member protrudes from a surface of a wind turbine blade that extends in a radial direction from a rotor head supported in a freely rotatable manner, includes a noise suppressing structure that suppresses the generation of a Karman vortex, which causes noise, on the downstream side of the diverter strip with respect to an airflow that flows at the surface of the wind turbine blade during rotation of the wind turbine rotor blade.

摘要： A lightning strike detector that can promptly detect a lightning strike to ensure safety and can accurately determine the position struck by the lightning with a simple, inexpensive, and highly reliable structure, is provided. The lightning strike detector includes an environment-detecting sensor member that detects a change in the environment of the internal space of a wind turbine blade, serving as a hollow structure, when the wind turbine blade is struck by lightning and is damaged, converts the environmental change into an electrical signal, and outputs the electrical signal; and a control unit (nacelle-side control system and ground-side control system) that receives the electrical signal, judges whether a lightning strike has occurred, and takes countermeasures against the lightning strike.
