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. 6. The tilts of the two airfoil sections comprising the articulated airfoil are determined by the heights of the Polish Yokes R03, R05 relative to the height of the Scotch Yoke R01, heights which are all defined by the rotation angle of the shared orbiting crank pin R21.
FIG. 11 depicts an alternative all-mechanical means for controlling blade tilts by means of Polish Yokes. Finally, an alternative embodiment to that shown in FIG. 13B, is considerably more than the chord length of the blades, shown as D22 in FIG. The assembly process would likely proceed in the following sequence: (a) assemble the exoskeleton, (b) mount the crankshaft, (c) install the strong vertical thrust rods within the side members of the framework, (d) install the connecting rods between these and the crankshaft, (e) install the moving-pivoting tilt rod structures within the framework, (f) install and engage the tilt control means within the crankcase, and (g) attach the airfoils to the vertical thrust rods and the moving-pivoting tilt rod structures. Other species of transducers in the relevant art employing only a single array of airfoils rely solely upon the aerodynamic physical mechanism similar to those accounting for the lift provided by airplane wings.

In addition, other components attached to the transducer are provided for converting power associated with tidal flow to useful electric power. Element P05 is an anchored pivot about which the suspended transducer can rotate in response to changes in the direction of tidal flow. The opposing synchronized translations and tilts of adjoining airfoils can be adjusted to introduce a valve-like (pneumatic) effect that can substantially increase power yield. FIG. 19 depicts the time progression of the movement of articulated airfoils subject to the control illustrated in FIG. FIG.

A significant difference between this transducer and the IC engine is that for each airfoil array both strokes comprising a full single cycle impart power to the load whereas in a two-stroke IC engine only one stroke is a power stroke, the other is a power-consuming compression stroke. This transitory process might be called “trap and release” which invites description in terms of pneumatics, specifically adiabatic compression and expansion which are portions of the thermodynamic Carnot cycle, rather than in terms of Bernoulli’s principle. Furthermore, the company Engineering Business Ltd in Riding Mill, Northumberland, England, built and tested an oscillating-wing hydropower generator, called “Stingray”, which produced an output of 150 kW. 13B. Chord length is defined here as the distance between the leading and trailing edges of the blade. 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.
The present device, in contrast, can be quite compact and light-weight, and suitable for mounting on the ground, in back yards of residences, or on roof tops, as well as presenting other mounting alternatives. The means for controlling the tilts of the arrays can be purely mechanical or can involve electromechanical means, the latter allowing dynamic adjustment to wind conditions. In the extreme case in which aerodynamics is totally supplanted the panel of airfoils can be described as a “distributed planar valve” that cycles between allowing passage of the wind with little impediment and the stalling of airflow altogether, as a function of the attack angle of the airfoil. Review of the NACA wing performance data base shows that articulating the airfoils in this fashion will typically exhibit more than double the peak lift one would obtain with a similar sized symmetric single-piece blade.
Thus, all of the force of the blade excursions will be transmitted to the even-numbered thrust rods and thus to the crankshaft. For each pair of blades, it will be necessary to push upwards on the articulation joint of the upper blade, and downward on the articulation joint of the lower blade. The tilt angle of the forward section is controlled by the articulation tilt rod R07, which tilts the forward section R31, while the main tilt rod R09, moves the rear section R33, as in the non-articulated version which appears in FIG. Because the pivot point joining the two portions of the airfoil is near center chord the overall vertical thrust imparted by wind is shared significantly with rods R07, R09.
Should the chord length of a representative blade be significantly longer than half the vertical excursion of the blade, as shown as D20 in FIG. In the case of a rigid blade with a single articulation, as shown in FIG. 19, the blades A401/402 are paired with A301/302. As the stroke progresses, blades A401/402 are convex upward, while blades A301/302 are convex downwards. 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.

In accordance with a ninth aspect of the device, the means to convert the linear excursions into rotary motion includes a crankshaft. 73-82, respectively. They showed that this type of power generator is capable of converting water flow energy into electricity. In accordance with a fifth aspect of the device means are provided for converting the linear excursions of the blades into electrical energy. In accordance with a twelfth aspect of the device the fluid comprises air or water. In accordance with a first aspect of this device, a reciprocating transducer powered by the kinetic energy of fluids includes an array of interleaved blades which include a first set of blades and a second set of blades, wherein each member of the first set is disposed between two members of the second set, except for the blades at the two extremes..
