image 9, each blade 422 comprises a tubular boom 524 which slips into a connector 520 on the hub 514 so that booms 524 extend radially from the axis 486 and are disposed substantially in a plane perpendicular to the axis 486 and parallel to the axis 418. The booms 524 are secured to the connectors 520 by, for example, welding. Each boom 524 is provided with a spacer 526 disposed transversely to the boom 524 and located a distance from the hub 514. The spacers 522 are secured to the booms 524, by welding for example, in such a manner that they are canted with respect to the generally planar disposition of the totality of booms 514; that is, with respect to the general planar disposition of the blade assembly 420. A blade end 528 is secured, by welding for example, to the distal end 530 of each boom 524; the blade end 528 being canted with respect to the blade assembly 420 so that the blade end 528 is parallel to the spacer 526 and spaced a distance therefrom.

Whitewater kayaking in Norway The use of limit switches in this manner to define the extreme dispositions of the shield 26 is in keeping with the overall concept of flexibility in design of the rotor electric power plant 10. Rather than determine anew the geometrical relationship between the shield assembly 16 and the fin assembly 18 when the construction of the rotor electric power plant 10 is varied, for example, in size, to take advantage of the prevailing wind conditions at the site of the plant, the relative orientations of the fin assembly 18 and the shield assembly 16 are adjusted in situ by the positioning of the limit switches (not shown).

While a detailed description of the wind driven power plant 10 will be presented hereinbelow, it is perhaps well at this point to provide a general overview of the plant 10 with reference to FIG. It is evident that the presently described invention provides a wind driven power plant capable of contributing to the generating capacity of a power distribution grid. In order to permit the efficient generation and widespread distribution of electricity, the frequency and amplitude requirements of electric motors used in industrial machinery and in home appliances have been standardized and electric power generation power plants and distribution grids are designed to supply the requirements of such motors.

6. In particular, the rotation rate control system 48 incorporates a high pressure switch 320 which, when closed, transmits an electrical signal from an electrical power source (not shown) to the gear drive 302, via conventional slip rings (not shown) on the rotor assembly 14 and an electrical conduit (not shown). Similarly, should the rotation rate of the rotor assembly 14 decrease below the lower extreme of its preselected range, the pumping rate of the pump 310 will decrease to such a value that the fluid pressure in the pressure tank 316 will decrease to a value below the actuation pressure of the low pressure switch 322. At this point, the low pressure switch 322 will no longer be actuated and, since the low pressure switch 322 is of the normally closed type, the switching members of the low pressure switch 322 will make electrical contact to transmit an electrical signal to the electric motor 308 in the gear drive 302, thereby actuating, as previously described, the gear drive 302 to move the shield 26 in such a manner to increase the exposure of the blades 22 of the rotor assembly 14 to the wind.

It is also an object of the present invention to provide a control assembly which senses variations in the rotation rate of the wind interception assembly and generates a signal from which the rotation rate is controlled. In order to effectuate the increased flow rate, the pump 310 must simultaneously establish an increased pressure in the pressure tank 316 in order to provide the increased pressure differential across the orifice 318 corresponding to the increased fluid flow rate. Once the blade assembly 420 has been turned from the direct facing relation with the wind, the rotation rate of the blade assembly 420 is under the control of the rotation rate control assembly 426. The initial angular displacement of the propeller assembly 414 will open the limit switch which prevents the blade assembly 420 from overshooting the direct facing relation with the wind when its rotation rate decreases so that subsequent adjustment of the connecting assembly 428 is made only by the closing of either the high pressure switch 486 or the low pressure switch 488. Accordingly, the blade assembly 420 will thereafter continue to rotate at a substantially constant rate to generate electrical power having the appropriate frequency and amplitude characteristics while the rotation rate control assembly 426, sensing variations in the rotation rate arising from variations in wind speed, transmits electrical control signals to the connecting assembly 428 to adjust the orientation of the blade assembly 420 with respect to the wind, thereby maintaining the rotation rate of the blade assembly 420 within the preselected, narrow control range.

The reversible electric motor 308, when actuated via the high pressure switch 320, is supplied with power to cause the gear drive 302 to turn the cog 304 in a direction to move the gear track 284 in the clockwise direction, as viewed from the top of the shield assembly 16. This results in the rotation of the shield assembly 16 to increase the masking of blades 22 extending in the direction 32, thereby decreasing the effect of the wind on the rotor assembly 14 to decrease the rotation rate thereof. Thus, the cog 580, coacting with the gear track 556, turns the blade assembly 420 more nearly into a facing relation with respect to the wind to increase the coupling of the blade assembly 420 to the wind, thereby increasing the rotation rate thereof.

These symmetrical structures are formed into the rigid shield assembly 16, as shown in FIG. The rotor assembly 14 comprises a plurality of rotor blades 22 (only one such blade 22 is shown in FIG. Dolor en el centro de la espalda . Also, a collar 178 is mounted on the lower rotor sleeve 126 near the mid-point thereof, and a plurality of connectors 180 are symmetrically spaced about and connected to the periphery of the collar 178 (only one of the connectors 180 is shown in FIG. 9), to which the cables 456 are attached, mounted upon and partially imbedded in the upper surface 446 of the support base 430 adjacent the wall 438. The tension in the guying cables 456 may be adjusted by turnbuckles (not shown) interposed therein. Each blade 22 is completed by forming a network of sail support cables, one of which is the outer sail support cable 184, between the rotor arms 160, 164 and attaching a sail 188 thereto.

As the wind speed increases, the rotation rate of the rotor assembly 14 will reach the preselected control range. Accordingly, rotation rate control is a necessity. 2. The hydraulic and electrical circuits of the rotation rate control system 48, which is constructed of conventional components, is shown in FIG. A windmill of this type is generally used to drive a mechanical system which carries out a desired function at the site of the windmill and the rate at which the mechanical system is driven is usually not critical.

In particular, if the direction 429 of the wind has changed, the wind will strike one side of the fin 574 and exert a torque thereon to rotate the fin 574 about the fin support shaft 552 until the fin 574 is aligned with the wind. In a generator, regardless of the specific details of its design, one or more windings are arranged so that the rotation of the shaft of the generator will result in a corresponding cyclic variation of the flux of the magnetic induction in the windings. The flange 134 has a bore 148 that is concentric about the axis 122 and which is sized to clearingly receive the main portion 78 of the central shaft 72, as also depicted in FIG.
