Again the imposed tilts cause nearest neighbors to be forced apart by the wind and, consequently, to drive the thrust rods in opposing directions. It is thus shown that during the first stroke, the thrust as the blades of the pair separate, drive the thrust rods in one direction, while during the second stroke the thrust rods are driven in a down direction. The time required for the blades to be driven apart, and thus the time period between strokes, will be a function of several factors: the size and number of blades, their weight, the friction of the components, etc. FIG. 6 depicts a perspective illustration of the lower portion of an embodiment of this device in which the pair of linear motors (A41, A42) providing tilt control have been replaced by a flat crankshaft driven by a motor. In this figure Scotch Yokes are shown as integrally affixed to vertical thrust rods D13, D14 and couple these to corresponding crank pins of the crankshaft A07.

FIG. 4 depicts the positions and tilts of the blades together with their corresponding engagement with thrust rods and tilt rods as time progresses. In accordance with a seventeenth aspect of the device a plurality of connecting rods, each having an upper and lower end, are included, wherein each connecting rod is rotatingly affixed at its upper end to a lower end of a corresponding thrust rod, and is rotatingly affixed at its lower end to corresponding crank throws. In accordance with a nineteenth aspect of the device each articulated airfoil further includes a forward section, an articulation joint, and a rear section, and further providing means for tilting the forward section, and means to tilt the rear section, thereby producing the articulated airfoil shape. 6 must provide a means for varying the rotational angle of the two crankshafts relative to each other. In accordance with an eighteenth aspect of the device the means for moving each of the tilt rods up and down includes one or more cams.
In accordance with a fourth aspect of the device, at the end of the second stroke the blades are in the same configuration as they were at the beginning of the first stroke, which may be repeated, at a controlled, synchronized rate. Accordingly, it is not necessary to link the bottom end of thrust rods T12 and T14 to the crankshaft. Thus, the thrust rods make a reciprocating motion, which is converted into a rotary motion, which powers the electric generator. 1, this thrust rod pair morphs into the pair T11 and T12, the racks, with the pinion T01 connecting the two thrust rods at their top, as shown in the detail of FIG. This clearly shows the combination of the two arrays functioning as planar valve rather than as a collection of “flying” wings. Furthermore, all of the embodiments of the present device use synchronized motion of opposing blades in reciprocating fashion, analogous to the operation of the internal combustion engine, rather than the random “flutter” effect of the Arnold patents.

Basic application of Bernoulli’s principles is not sufficient, rather the effects related to the interaction between nearest blades acquire a pneumatic character. By employing two interleaved airfoil arrays that move in opposition, one acquires opportunity to supplement or even supplant this “lift” mechanism with pneumatic effects. Embodiments in which the blade tilts are electrically controlled producing this “trap and release” character simply require an adjustment of programming, assuming the blade chord vs spacing is as described above. Most of the embodiments described herein would mount upon either a rotatable horizontal table (“lazy susan”) or a platform floating on water permitting the transducer to be oriented relative to the direction of the wind. Pastilla para dolor muscular . Structural struts P03 and P04 attach to the lower frame of the transducer and to the anchored pivot P05 to maintain the transducer at a fixed distance from the anchored pivot.
