A wind powered variable area exit aperture electric generating system having configurable, adjustable duct side walls by which means the ratio between the intake cross-sectional aperture area and the exhaust cross-sectional aperture area may be varied for maximum air molecule flow through the duct, leading to ideal maximum electrical output for any given air mass input. The planar characteristic and angular dispersion of the mutually leading edge coupled extended flaps, and the regular square interior housing result in complementary internal vortices developed at the trailing edge of the planar architectural surfaces.

What is claimed is: 1. A Ducted Fan Wind Turbine, hereinafter and before, DFWT, device for safely and quietly producing electrical power without added induced mechanical vibration from an air molecule mass/velocity throughput, standing alone in a field or in multiple DFWT devices in the field combinations: and most especially to be mounted on turbulent, windy, building tops, with augmented increased wind input stream flows measurably typical of the tops of buildings and other structures, comprising, in combination: a turbine type, dynamically mass balanced multi-bladed fan located with an aerodynamically regular and balanced duct, said duct configured as a regular four solid sided short square, open to the front and the back through a very highly air molecule porous metal or other relatively permanent, strong mesh to prevent the ingress or egress of objects of any size and type into or out of the fan power cell, with four externally affixed and mounted flap structures, hinged to each other in such a way that the front aerodynamically leading edges of the flap structures and the aerodynamic leading edges of the four sided centrally located fan power cell are hinge attached to each other and coincident; means in each said DFWT device to alter the exit aperture air molecule volume, or equivalent cross-sectional exit aperture of said DFWT device, via the expedient of extensible electrical or other operational linear actuators, by which the planar surface of said flaps may be extended further away from or nearer to the solid planar sides of said central power fan square, so that the ratio of the duct entrance cross-sectional area, to the duct exit cross-sectional area may be varied to achieve the highest possible fan rotational velocity; a voltage is sensed via a voltage/velocity electrical signal derived from an integrated fan shaft mounted N-I-B generator electrically transmitted to a logic controlled power amplifier comparator from which electrically controlled linear flap actuators are powered. 2. The device of claim 1 wherein said center power fan square with attached leading edge flaps, through which a vertical fan mounting pipe extends well beyond the bottom power cell planar surface, attaches via the expedient of said projecting power cell pipe into a outer larger diameter, base mount pipe on the top of which is situated a TIMKEN짰 type tapered roller bearing in such a way that the center fan power cell, together with the leading edge hinged attached flaps may freely rotate thorough a full 360 degrees and greater without compromising the fan shaft attached electrical power generator from which an electrical cable extends onto a stationary voltage detection and inverter structure; said electrical connection to be through a MERCOTAC짰 or other type of high electrical conductivity, low loss rotating mercury wetted or other type relay, so that said DFWT with integrated internal wiring may rotate freely through more than 360 degrees without compromising the need of said throughput electrical wiring to attach finally to a stationary and fixed termination; said base pipe is connected to, and supported vertically by a flat, planar, extended steel or other strong material plate, or equivalent attachment means, through which means the DFWT unit may be firmly attached to any strong roof or other surface element of a building or other structure. 3. The turbine type DFWT device of claim 1, in which a nested structural, rotation capable concentric upper cell inner pipe, and lower base pipe outer attachment, with integrated TIMKEN짰 type tapered roller bearing, and high conductivity rotation capable relay, form a double wall nested pipe mast structure, tested, and testable to be capable of safely withstanding any wind load which the building itself is capable of withstanding. 4. The turbine type DFWT device of claim 1, in which the extended planar sides of the regular four sided square fan containing power cell, in leading aerodynamic hinged edge conjunction with the extended planar surfaces of the four extended flaps creates a variable volume behind the turbine type central fan, which variable volume in conjunction with sharp trailing edge planar surface discontinuities of the power cell sides, and the trailing edge discontinuities of the flap edges, results in the formation of aerodynamic trailing edge vortices, which cylindrically shaped vortex rotors facilitate the more rapid and efficient exhaust of input air mass/velocities through the DFWT system when compared to the frictional losses and flow limitations of traditional laminar flow methods, in which stream flows adhere to and track extended planar surfaces, in previously patented ducted fan and structure augmented wind turbine fan designs; said cylindrically shaped vortices may be made larger or smaller, more or less transit capable and energetic via the expedient of the intelligent opening and closing of the extended planar flap structures relative to the fixed position of the extended planar sides of the centrally located fan power cell. 5. The turbine type DFWT device of claim 1, to which said central power shaft of said balanced turbine type fan is attached a Neodymium-Iron-Boron, N-I-B, type permanent magnet pancake type generator, in which centrally located solid pie wedge stator conductive elements can be configured in any number of series parallel combinations, to be driven by extended co-planar complementary attractive facing rotor pairs of said N-I-B magnets arranged in a single pair per pie wedge conductive stator element configuration; since the fan rotational velocity expressed as a voltage output of said low input impedance N-I-B type generator depends upon the rotational velocity of said turbine type driving fan, the output of said generator can be sampled to form the input to a logic controlled rotational velocity to voltage comparator which in turn drives power amplifiers which in turn individually drive each of one, or two, or three, or four of two horizontally oriented, and vertically oriented, linear electric actuators, which open and close attached flaps relative to fixed power cell extended planar surfaces, so that the cylindrical vortex augmenting air molecule mass/velocity driving elements can be variously and individually controlled via individual, or paired flap extensions. 6. The turbine type DFWT device of claim 1, in which a bottom horizontally oriented flap can be pitched outward, down, or relatively inward, up, in order to produce more or less lift in co-planar conjunction with the roof top extended planar pressure zone, so that the relative mass of the DFWT, and the tendency of the entire DFWT unit to pitch backward against the concentric double nested rotationally capable pipe attachment to the base, can be off set dynamically by the lift generated by said bottom flap. 7. The turbine type DFWT device of claim 1, in which a top flap can further control the relative lift of the DFWT device, generated by a bottom flap, to offset the static mass of the DFWT and the backward pitching tendencies of the DFWT unit against a central support pipe and bottom base attachment. 8. The turbine type DFWT device of claim 1, in which said four complementary leading power cell hinged flaps form a configurable duct, in which all four sides may be independently configured alone, in response to an asymmetric input air mass force, or configured dependently together; both types of configurations to be logically evaluated by the rotational velocity to voltage sensor, as to whether or not any given independent or dependent configuration results in greater or lesser power output through the system. 9. The turbine type DFWT device of claim 1, in which four normally identically configured leading edge attached flap structures form a truncated pyramid structure, attached to an interior open front and back square, in which the four regular, normally identically oriented sides of the pyramid are truncated into a frontward opening, and terminated aft ward by another opening, the cross-sectional area of which depends upon the relative angle of each exterior flap element to the planar out sides of the interior square; the aerodynamic characteristic of such a horizontally oriented truncated pyramid structure is that of a constantly expanding exterior volume relative to a partially fixed, but aft ward limited interior volume, with the face on into the wind steering characteristic of a pressure controlled vertical lifting surface, symmetrically drag normalized in two planes, in which the vertically generated lift is expressed as a torque moment inwardly against a rotation capable bearing; laterally dispersed, to either side extreme, vertically oriented lift elements form drag force induced torque moments tending to instantaneously orient the open front aperture of the DFWT directly into the wind against the rotational velocity generated, bicycle wheel gyroscopic moment of the fan rotation itself. 10. The turbine type DFWT device of claim 1, in which four normally identically configured leading edge flap structures form a truncated pyramid structure, attached to an interior open front and back planar side square, the truncated pyramid structure open front and back, with the front cross sectional area in front of the fan fixed, and with the rear ward, back, cross-sectional area configurable as to cross-sectional area, and increasing or decreasing interior volume, with the further aerodynamic purpose of providing an equivalent flap edge to edge seal, so that the air mass in transit through the duct, behind the fan, may be maintained without side edge leakage, and consequent duct interior and exterior pressure equalization prematurely before a rear edge flap duct termination.
