A wind powered generating device, which produces usable electricity. This wind machine sits high on a tower to take advantage of turbulent free wind. The tower is made of wooden poles. Two of these are placed into the ground at a distance that can support a third pole that places the wind machine into the wind stream. The third pole or main mast is placed between the two support; poles and has a hinge point about half way up, so the main mast and the wind machine can be lowere d to the ground. The raising of and lowering of the main mast is controlled using a winch at the base of the two support poles. The wind machine has a shape much like that of an airplane with one propelle r at each of the two wing tips. There are two rotor blades that are driven by the wind in place of the propellers. The tail section still controls the wind machine wi th the rudder, keeping the rotor blades facing into the wind. The rotor blades are set out side by side and turn in opposite direction s. These rotor blades are mounted on short shafts, and there is a means to chan ge the direction of the shafts mechanical energy 90 degrees inward so the drive shafts are in alignment. There is also a means to vary the RPM of these drive shafts at these junctions. A pair of driving discs or drive cones (one disc or conefor each rotor blade] is used and driven wheels or driven cones run on said drive disc or drive cone. The driven wheels or driven cones turn the drive shafts and regulate their RPM. By changing the position of were they run on the drive discs or drive cones. At the midpoint, where the two drive shafts almost meet the counter rotating alternator sits in alignment or just back towards the tail section. The two alternator input shafts are connected to the two drive shafts coming from each of the two rotor blades. The drive shafts are connected directly to each of the counter rotating alternators tw o input shafts in the case where the RPM. is regulated at the rotor shafts and drive shafts junctures as just mentioned. Where the counter rotating alternator is set back towards the tail section, there is either a fixed system, or a different variable system in place. The fixed system has pulleys and belts to speed the alternators two counter rotating shafts. The variable system uses a variable "V" belt clutch and pulley set up. This machine uses the two counter rotating rotors to drive: a counter rotati ng A/ C electric generator (alternator). A single phase or three- phase power may be produced. By setting two rotors side by side it is possible to avoid "wind shadow" effect. The moving parts move relatively slower than with conventional wind machines, therefore there is minimal wear on parts, lass wind energy is need ed to produce electricity, therefore lower wind speeds can be utilized. This device can be used with other prime movers in tandem or singularly to produce usable electricity. As a single input the counter rotating alternators rotational speed can be increased by twofold, like the tandem unit. This is accomplished by using a counter shaft with a main shaft. The two shafts drive the counter rotating alternator components. The rotational speed can be increased farther by a ratio increase at this point, using pulleys or different gear sizes. The overall increase in RPM. by gearing can be kept to a minimum, so the energy saved can be used to produce more electricity. This principal can be applied to other uses. By imputing electricity and creating a counter rotating electric motor, one could combine action and reaction force s together to increase the overall performance. There are three ways to do this. The first uses the same method just explained with the single input counter rotating alternator. The counter rotating motor uses a counter shaft and a main shaft to deliver the combined action and reaction forces. The second method uses a ge ar set with small stationary planetary gears to create a single output shaft. The third way is to use each shaft separately to create part of its own powe r with one, and to drive with the other. The motor could drive a car's wheels with the action force and drive an electrical generating device with the reaction forces, therefor e creating part of its own electrical power. Example: The harder the counter rotating electrical motor works to move the electric car's wheels, the harder it will drive the generator. The load from the electric motor draws power from the batteries. The load on the generator to recharge the batteries counter-acts the electric motor, effectively acting as a mounted motor. |
