  • Patent number: 9945389
    Abstract: A modular fan assembly includes a center hub assembly and a first blade attached to the center hub assembly. The center hub assembly includes a first plate having an outer edge, and a second plate having an outer edge. The first blade has a mounting pad and a working portion. The mounting pad is positioned in between the first plate and the second plate. The working portion extends beyond the outer edges of the first and second plates of the center hub assembly. A thickness of the first blade is smaller proximate the outer edge of the first plate than at the mounting pad to create a first gap between the first blade and the first plate at the outer edge of the first plate.

  • Patent number: 9945358
    Abstract: A blade adjusting device for a wind turbine is connected to a plant safety chain and can open and close the plant safety chain by activating a switch. If a fault is detected in one of the blade adjusting devices, the respective control unit can open the plant safety chain. By opening the safety chain, a signal is sent to the blade adjusting devices, and so all the blade adjusting devices initiate a synchronous safety operation of at least two rotor blades when the signal is received.
