4. Thus each blade 150 functions more or less in the same way and produces the same results as the one in FIG. Flap 184 is a bistable member which can be swung between two extreme positions by at least one toggling mechanism indicated generally at 186 located inside main body 180. The toggling mechanism 186 may be substantially identical to and operate in the same way as the one depicted in FIG. Referring FIGS. 8 and 9, in this dual channel embodiment of the apparatus, the oscillating blades 150 are pivotally mounted in channels 124 a and 124 b of housing 122 by way of shafts 160 which may extend the lengths of the blades adjacent to their leading edges. This maximizes the water’s velocity through the housing 122 and thus the harvestable power from the water.

In general, my power generation apparatus comprises at least one blade or vane having the general shape of a symmetrical aircraft wing, a segmented articulated rudder or the body and tail of a fish. 3. The blade is made geometrically cyclically nonsymmetrical by dividing the blade into two parts, namely a main body 66 and a flap 68, those two parts being hinged together along their lengths by shaft 34 or an equivalent.
4 and 5 (and 12) control systems, the toggling of the flap 68 at the TDC and BDC positions of the blade 20 is due mainly to net fluid pressures on the blade and flap, combined with the inertial and angular momentum forces as described above. The vertical position of the follower is controlled by a cam 106 which may be rotated by a lever arm 108. Arm 108 may be progressively swung between a HIGH position wherein the cam follower 105 is opposite a low point of the cam 106 so that master cylinder pump 104 delivers little or no fluid to cylinder 98 in blade 20. Resultantly, actuator toggles flap 68 between its two maximum positions as described above. Thus, the flap 68 can pivot or bend relative to main body 66 independently of the pivotal motion of the main body on shaft 24, as shown in FIG.
This lift force can be several times greater than that of a conventional aerofoil shape, depending upon the relative velocities. When the blade nears TDC or BDC, the fluid, by the transient machine geometry, is made to simultaneously accelerate on the blade side nearest the boundary while decelerating on its opposite side, causing a net pressure difference over the blade; this simultaneously increases the output torque produced of the blade and decisively aides the toggling of the flap. 4, the flap has an inner end 68 a that extends beyond shaft 34 into main body 66 which is notched or hollowed out at 66 a to provide clearance for the swinging motion of the flap end 68 a. 8 hydro-powered apparatus may not be required because the mass of the rotating Magnus rollers can sometimes provide the necessary inertia to store the intracycle energies generated near the TDC and BDC positions.

Another object of the invention is to provide such apparatus which can utilize the energy in moving wind or water to produce shaft torque to generate electrical power without harming a significant portion of the bat, bird or fish populations that attempt to fly or swim thru them. Thus, the lower end of each blade shaft 160 extends through the sealed housing lower wall 122 b into the power converter assembly 152 where it is connected to one end of a crank arm 162 that is also pivotally connected at 163 to one end of a link 164. The opposite end of that link is pivotally connected at 165 to one lobe of a two-lobe crank shaft 166 whose upper and lower ends 166 a, 166 b are journalled in the housing wall 122 b and a housing wall 152 a of assembly 152, respectively. 3 is associated with each oscillating blade 150. More particularly, each crank arm 162 has an end extension 162 a on the opposite side of its shaft 160 from the associated link 164. That extension carries an arcuate rack 170 which meshes with a pinion 172 on a shaft 174 rotatably supported between housing wall 122 b and the wall 152 a of assembly 152. Tengo un dolor de espalda muy fuerte . Shaft 174 carries a flywheel 176 which is rotated in one direction or the other by the oscillatory motion of the associated blade 150. Thus, each flywheel 176 captures the energy of its oscillatory blade 150 at the opposite ends of the blade excursion and releases that energy nearer to the middle of the oscillation half cycle of the blade in the same manner described above in connection with the FIGS.

2, a link 32 is connected at its lower end to a pivot 34 a mounted on the side of blade 20 only coincidentally concentric to shaft 34 extending the length of blade 20. The upper end of that link is connected by a pivot 36 to a crank arm 38 adapted to turn the input shaft 42 a of a gear box 42 in the direction shown by the arrow. 3, wherein edge 20 b is positioned close to the surface of water W. These two positions coincide with the lower-most and uppermost positions of crank arm 38 in the crank cycle.
Under the influence of the water flow, each blade 150 oscillates within its channel 124 a, 124 b between extreme positions wherein its flap 184 is adjacent to the bed sections B2-B4 at opposite sides of its channel. Conversely, the same process occurs when the flap is angled toward the BDC position of the main body at BDC, the moving fluid stream is momentarily trapped between the nearby boundary and the flap thereby tending to swing the blade toward the TDC position of the main body. The flap may be pivoted or bent between two positions by a toggling mechanism 224 c in the main body. 13A. This results in the two blades 180 being in close dynamic balance throughout their oscillation cycle so that they swing smoothly between their two extreme positions. This moment in the cycle is when the blade is being propelled by the much larger Wind/Water Hammer force and where the drag force itself makes its maximum positive contribution to the output torque.

13B, the surface speed, SR, of the Magnus roller increases to about 4.5 times that of the start up wind speed as the roller nears midcycle, making its theoretical coefficient of lift, CL, at that instant about 25. Also, this is at the exact place in the blade cycle where the most favorable geometries for torque transmission exist. Diarrea fiebre dolor muscular . When used in my machines, this allows them to be utilized competitively in lower speed wind regimes, commonly found in or near metro areas and at lower tower heights, greatly expanding the locales where the apparatus can be deployed competitively. The lower end segment 210 a of the tower that is below axle 208 may define a tank or container 212 for holding water, sand or a heavy metal such that the tower segment 210 a constitutes a counterweight to the weight of apparatus 200 at the top of the tower.

A mirror image of that structure is connected to the lower set of straps 240 c of the housing skeleton. As shown in these figures, the leading edge bracket 226 a of the vertical vane 226 is connected between the upper and lower tubes 240 b at the rear of the housing at a location therealong that centers the vane between the two blades 224. Preferably, bracket 226 a of the vane is pointed or streamlined as shown so that the trailing edges of the oscillating blades 224 can use it as their TDC boundaries, i.e. Mounted to the rear of housing 220 opposite its entrance 220 a is a large tapered vertical vane 226 having a streamline leading edge bracket 226 a centered between blades 224 and extending parallel to the vertical axis of housing 220. Preferably, vane 226 is a light-weight hollow subsection composed of first and second vertical arrays of horizontal ribs 226 b.

Each blade has a leading edge and is mounted so that it can pivot about an axis extending the length of the blade adjacent to the leading edge thereof and typically on the leading edge radius centerline. 20), these forces cannot be transmitted to the IMAG at that instant. The magnitude of the force produced by this Magnus effect is proportional to the ratio SR/SW times the square of the wind free speed, SW, creating lift forces an order of magnitude higher than those produced by conventional blades, even with flaps, and especially at low wind speeds. Thus, when the blades are near their TDC and BDC positions, they experience the same fluid flow regimes and forces described above for the invention embodiments that rely on hydropower, vis a vis cyclically blocking the free stream flow. For all of those applications that do not involve dams and where a fluid flow velocity is already established within a pipe(s), such as in drainage, waste or fresh water piping systems, the siphon and draft pipes would, of course, not be required.
