| 20090208334 | Wind Flap Brake Assembly for Wind Turbine - A brake assembly for use with a wind turbine. The brake assembly comprises a movable wind flap for attachment to a tail assembly of the wind turbine, the wind flap being configured to assume a first closed position during normal operation, and a second open position when incoming winds exceed a predetermined velocity threshold. Provided on the wind flap is a trip rudder assembly for cooperating with incoming wind to urge the wind flap into the open position. A counterbalance assembly is also provided for biasing the wind flap into the closed position. The wind flap in the open position effects a redirection of a portion of the incoming wind, urging the wind turbine to assume an oblique position relative to the incoming wind, effecting a reduction in rotational velocity of the wind turbine. | 08-20-2009 |
| 20090104039 | Curved Blade for Wind Turbines - A curved blade for use on horizontal wind turbines, the blade comprising a substantially semicircular tip portion, a substantially semicircular counter-tip portion opposite the tip portion, and a body portion extending between the tip portion and the counter-tip portion, the body portion being further defined by a concave curved trailing edge and a convex curved leading edge. | 04-23-2009 |
| 20090016887 | Rotor Drum for Multiple Rotor Wind Turbine - According to embodiments described in the specification, provided is a rotor drum for use with a multiple-rotor wind turbine, the rotor drum being mountable on a generator shaft of a generator. The rotor drum comprises a plurality of rotors, each rotor being configured to permit a mounting of a plurality of blades. The rotor drum further comprises a plurality of cross straps affixed to the plurality of rotors for maintaining each of the plurality of rotors in a predetermined spaced-apart relationship. The rotor drum is provided with a mounting coupler provided on at least one of the plurality of rotors for affixing the rotor drum on the generator shaft. | 01-15-2009 |
