  • Patent number: 8734104
    Abstract: A wear-free, self-contained control device for an aerodynamic emergency brake of a wind energy converter is presented that comprises multiple components in order to provide a most effective means to control the rotation of a vertical axis wind turbine by a brake, which is able to activate itself without external actuation in malfunction situations and is able to shut down the vertical axis wind turbine. Therefore, a mass element is utilized to store mechanical energy which in turn is used to deploy an aerodynamic braking operation. It also represents a means to control and limit the amount of torque, as absorbed by the turbine in high-wind conditions, and thus provides the ability to harvest electrical/mechanical energy, beyond the normal operational wind speeds of turbines.

  • Patent number: 8047787
    Abstract: A turbine rotor blade for use in an industrial gas turbine engine in which the blade includes a root section with a fillet region formed between the root and the platform of the blade. The platform region includes a diamond shaped root slot to discharge cooling air from the internal cooling passage out through the trailing edge of the blade. The diamond shaped cooling slot of the present invention comprises a smaller radius at the upper and lower corners and a much larger radius at the mid section of the slot. The cooling slot is positioned in the trailing edge root section where the upper corner is positioned above the fillet run out location. The diamond shaped cooling slot thus minimizes the high stresses induced by the stress concentration from the cooling slot and the fillet run out location.
