As shown the thrust rod K03 is constrained to move vertically and the Polish Yoke member K01 only moves vertically relative to it, as it is constrained by a vertical slider (not shown in this drawing.) Again it should be stated that embodiments that employ all-mechanical means are especially appropriate for airborne and tidal applications whereas embodiments employing electrical control of blade tilt are especially appropriate for achieving maximum average power yield. It is assumed generally for wind power applications that this transducer would be mounted upon a platform that rotates azimuthally about a vertical axis permitting orientation of the transducer (a “panel”) relative to the prevailing wind for maximizing the power yield and, when storm conditions are extreme, to present a minimal cross-section to the wind. By using a single electric motor the complexity of the electronics for control of the array tilts is reduced. It can be made in a particularly light fashion for airborne applications.
2008 in U.S. 2008/0148723. In this device an airfoil is mounted on a shaft such that the airfoil can be excited into a pitch oscillation about an axis at or close to the leading edge by actuating a trailing-edge flap. Column 4 portrays an early stage of the second stroke. In accordance with a third aspect of the device, it includes means for tilting the blades to a second position so that, during a second stroke of the transducer, the leading edge of each blade of the second set is tilted upward away from the leading edge of each blade of the first set, which is tilted downward, so that the passage of the fluid causes the blades of the second set to linearly rise and the blades of the first set to linearly fall, creating linear excursions thereby.

Since the belt or chain F03 in this embodiment is actually a timing belt or chain, the preferably implementation would be one in which the belt or chain F03 would be a “knobby” chain such as those intended for use on mountain bikes, and wheels F04 and F06 would have notches which complement the knobs on the chain to avoid slippage, which would adversely affect the phase tracking of the crankshafts. In addition, other components attached to the transducer are provided for converting power associated with tidal flow to useful electric power.
The right column illustrates the disposition of the blades at the end of the first stroke and the beginning of the following stroke. In this figure the leftmost column illustrates the two interleaved arrays of sailcloth blades in sectional view at the beginning of a stroke. Sliders J01, J02 ensure the Polish Yokes only move vertically, and are affixed to the exoskeleton. In near proximity Polish Yokes J03, J04 couple crank pins co-linear with the thrust pins to affect the tilt of the blade arrays via the connecting rods J23, J24. This device depends upon-and greatly benefits from-continuous control of the tilts of the interleaved airfoil arrays. Because the two nearly identical airfoil arrays move in opposition in the embodiments described herein, the transducer as a whole is inertially neutral. In accordance with a tenth aspect of the device the means to convert the linear excursions into rotary motion includes one or more Scotch Yokes.

One end of each is coupled to a crank pin, or throw E03, E04, on the auxiliary crankshaft E02, and the other end is coupled by a wrist bearing or bushing E05 to the tilt rods A21,A22 that couple to the trailing edges of blades in each array. Libro el dolor de espalda y las emociones . Initially, as shown in the column 1, the blades are oriented horizontally in pairs, the blades of each pair parallel to each other. In accordance with a second aspect of the device, it includes means for tilting the blades to a first position, so that, during a first stroke of the transducer, a leading edge of each blade of the first set is tilted upward away from a leading edge of each blade of the second set, which is tilted downward, so that the passage of the fluid causes the blades of the first set to linearly rise and the blades of the second set to linearly fall.

The thrust rods of FIG. Blades A1,A3,A5 are pivotably coupled at their ends to thrust rods A11, A13 by means of spars A52, FIG. The rocker arms have bushings or cylindrical bearings located approximately midway along their length, said bushing or bearings riding upon the cam guide surface. Item P01 is a buoyant member intended to maintain the transducer in an erect position, as shown in this figure. 7, a device for the control of blade array tilt angle synchronization using a single linear motor F01 is shown. In accordance with a sixteenth aspect of the device means are provided to move the tilt rods up and down, thereby changing the attitude of the blades. 19 are articulated airfoils, the relationship between the forward sections and rear sections changing as the progression proceeds. The two interleaved arrays are linked to opposing crank pins on the crankshaft and hence can only move reciprocally in absolute synchronism.

Two full strokes constitute a full cycle. When the cycle begins, as shown in Col 1, FIG. DESCRIPTION OF THE EMBODIMENTS Referring first to FIG. 9, an embodiment of the cams employed in the all-mechanical embodiment of the device 810 shown in FIG. Que puede ser un dolor de espalda . This axis and the spars are all mutually parallel.
