The tilting frame has a support cable connecting the major/minor gin poles. The minor gin pole can pivot relative to the major gin pole so that the longitudinal axis of the minor gin pole can be perpendicular to the longitudinal axis of the major gin pole.

The invention relates to an apparatus for producing a plurality of spaced apart drilled pits in the soil with excavated soil displaced radially outward to form an annular shape mound around the perimeter of the newly drilled pit. The earth boring/drilling device is a compact, portable and highly maneuverable power driven device which is self-propelled or towable.

The earth boring/drill device is arranged on a chassis with a plurality of upwardly depending support posts connected by horizontal support elements along with a mechanical means of reciprocating up and down a motorized power auger comprised of a shaft with a helical blade and cutting tips of hard wear-resistant material on the cutting end to drill a pit to a predetermined depth and predetermined diameter and then mound up excavated soil in an annular shape around the perimeter of the drilled pit as the auger is disengaged.

The first profile body extends from a first leading edge to a first trailing edge with a first chord extending form the first leading edge to the first trailing edge and being perpendicular to the radial direction. A plurality of flow deflectors extend along either the pressure surface or the suction surface within the lift generating section of the blade. The plurality of flow deflectors define a second profile body extending between a second leading edge and a second trailing edge with a second chord extending between the second leading edge and the second trailing edge. The second profile body defines an outer surface extending vertically from a base portion of the plurality of flow deflectors such that the base portion is configured to be disposed on the respective pressure surface or suction surface along which the plurality of flow deflectors extend therefrom.

The present disclosure is directed to a gearbox repair apparatus for repairing a bore hole of a gearbox torque arm. In certain embodiments, the apparatus includes a mounting structure configured to mount to the torque arm. The mounting structure includes a through hole that aligns with the bore hole of the torque arm when mounted thereto. As such, when mounted to the torque arm, the mounting structure is configured to locate a boring bar at a center of the bore hole such that the boring bar is perpendicular to a face of the torque arm. Further, the mounting structure is configured to receive the boring bar through the aligned through hole and bore hole such that, when inserted therethrough, the boring bar is configured to machine and thus repair the bore hole.

The present disclosure is directed to a rotor blade assembly for a wind turbine. The rotor blade assembly includes a rotor blade having exterior surfaces defining pressure and suction sides, and leading and trailing edges extending in a generally span-wise direction between an inboard region and an outboard region. The inboard region includes a blade root having a rounded trailing edge. Further, the rotor blade assembly further includes at least one airflow separation element mounted to either or both of the pressure or suction sides of the rotor blade within the inboard region and adjacent to the rounded trailing edge. In addition, the at least one airflow separation element corresponds to a contour of the pressure side or the suction side of the rotor blade. As such, the at least one airflow separation element is configured to provide a fixed airflow separation location in the inboard region during standard operation.

15100727Nourian M TETRAULTNourian M. Tetrault

A wind turbine for residential lots has a lower stationary inner tube supporting an upper outer tube rotatable about the inner tube. The upper tube supports a shaft supporting a generator, series of angled wide-width blades producing increased torque, and an elongated high-angled nose cone deflecting wind to an outer blades area increasing effective wind-speed providing power output of a turbine of about 120-130 feet; a second section of upper tube supporting a hinged-tail having a pivotable solid planar section hingedly attached to an open planar section fixedly attached to the upper tube; a computer-controlled actuator causing solid planar section to pivot into the wind at a pre-determined setting causing the upper tube to rotate turning the blade's plane of rotation out of the wind reducing their rotational velocity eliminating overheating of the generator providing for it to continue producing power in winds greater than 60 mph.

F03D 7/02

The invention relates to a control apparatus and method for controlling the rotor blades of a wind turbine, and in particular to controlling the rotor blades during an extreme wind event. An extended mode of operation of the wind turbine rotor beyond the cut-out wind speed is provided. In the extended mode of operation, the pitch of the wind turbine blades is actively controlled so that the rotor and the generator idle at a designated rotational speed. The rotational speed may be relatively high, say 15 to 20% of the nominal speed, compared with minimal speeds experienced by purely feathered wind turbine blades, and may be further controlled as a function of the incident wind speed. Output power control in the extended mode may be zero but is preferably a low, but non-zero value. The output power so produced may then be used as an auxiliary power source for controlling the wind turbine in situations where the utility grid fails.

A system and method for reducing oscillation loads of a wind turbine induced by high turbulence and/or combined with other environmental conditions are provided. The method includes determining at least one wind parameter at the wind turbine; monitoring an operating condition of the wind turbine; determining, by a processor, a variance of at least one of the monitored operating condition or a plurality of the wind parameters, wherein the variance is indicative of an oscillation occurring at one or more wind turbine components; determining, by a processor, an operating set point based on the variance; and, operating the wind turbine based on the operating set point when the variance indicates that the oscililation has a frequency within a certain frequency band so as to modify the frequency, wherein the modified frequency is outside of the frequency band and reduces oscillation loads occurring at the one or more wind turbine components.
