| CLAIMS 1. This invention provides for aeronautic & robust Fan Wind Turbines which can survive typhoons, cyclones & hurricanes of up to 250mpH (400kpH) (strongest on record, not including tornados) by virtue of the aeronautic design, robust construction, low aspect ratio & fully neutral featherability of propeller blades (Figs 1 , 2, 3, 4, 5, 6, 14) and Guy Stays & Guy Anchors (Figs 14, 15). This level of durability is not enjoyed by large capacity wind turbines with large aspect ratio sails (propellers) of the current state-of-the- art. 2. This invention provides an autonomous self-regulating control system by means of an elevator, which moves up & down(in relation to wind speed) on the trailing edge of a horizontal fin to trim or fully feather propeller blades thru levers, tension bars, slide mechanism, rack & pinion gears, bevel gears & propeller discs (Figs 1 , 2, 3, 4, 5, 6, 14), which are adapted to the control of the Propellers in a Fan Wind Turbine (Figs 3, 4, 5, 6). 3. This invention provides for Built-in Derricks for self-erection of the heavy components, such as, the propeller without the need for heavy construction cranes. Furthermore, all the heavy components present in the nacelles at the top of the current state-of-the art large wind turbines have been eliminated or moved to the base (Figs 1 , 2, 3). 4. This invention provides for a square-cornered, concentric, catenary- sided HP-CAES Reserve Tank System with a Bolted Joint Tank design (Figs 7, 8, 9, 10), which makes possible the rapid & economical construction of a manageably sized vessel capable of containing a sufficiently large volume of sufficiently high pressure air to store enough energy for grid or industrial applications in a manner that eliminates: welding, stress relief, spherically dished plates or excessively thick tank walls. This invention needs only thin rolled steel plates (using only two dimension bending) which are easy & economical to produce (not three dimensional dishing). 5. This invention provides for combining the functions of the Transfer Valves & Regulator Valves used in previous MWTS inventions in order to drastically reduce the total number of valves, while maintaining all the benefits of both the Transfer Valves &the Regulator Valves used previously. The new invention uses Transfer Valves alone with graduated weights to provide the pressure differentials between ring tanks while still allowing the extraction of inner tank high pressure air during periods of wind quiescence and without having Regulator Valves exposed to the outside. 6. This invention provides for Dispatch Valves (Fig 7, 8, 11 ), which may be Butterfly Valves, such that pressurized air may be released in seconds for the immediate dispatch of electric power. 7. This invention provides for an Underwater HP-CAES System which may receive high pressure air directly from the high pressure stages of the wind turbines into submerged vertical tubes at depths which utilize high water pressure to contain high air pressure, thereby, minimizing the structure needed to contain the high air pressure, while at the same time preserving the heat of the highly compressed air. |
SPECIFICATION a)This Madson Wind Turbine System (MWTS) improvement provides for a more robust aeronautic (aerodynamic)design (Figs 1 , 2, 3, 4, 5, 6, 14, 15) having propellers (Figs 2, 4, 5, 6) which may be enclosed between a central nose cone &an outer cowling(Figs 1 , 2, 3, 5, 6) in an aeronautic configuration which is more resistance to storms of up to 250mpFI (400kpH)in which a nose cone (Figs 1 , 2, 3, 5, 6)together with a cowling (Figs 1 , 2, 3, 5, 6) efficiently harvest & direct hub area wind to fan propellers for a stronger wind flow to generate more energy. This MWTS improvement has a more simplified & efficient self-regulating mechanism (Figs 3, 4, 5, 6) suited tofan propellers, including a more efficient linkage between the elevator, which moves up & down(Fig 3), the trim slide mechanism(Fig 3)&rack & pinion gears (Fig 3) which move back& forth along the propeller shaft to convey trim actuation by trim tension bars to bevel gears (Figs 4, 5, 6 )in the nose cone to drive propeller disks (Figs 4, 5, 6) which feather propellers (Fig 2, 4, 5, 6) up to a fully neutral angle depending on wind strength(Figs 1 , 2, 3, 4, 5, 6). The elevator (Fig 1 , 3), Slide Mechanism, Rack & Pinion Gears, Bevel Gears & Propeller Discs are connected & driven by Tension Bars, so that all components act together (Fig 3, 4, 5, 6). b) This MWTS Improvement further provides for nozzle cone with a convex curve (Figs 1 , 3, 5) to induce a vacuum behind the propellers to drive the propellers more effectively by accelerating the air flow. c) This MWTS Improvement eliminates, at least, the rear built-in derrick to further reduce cost (Figs 1 , 3). d) This MWTS Improvement provides for High Pressure - Compressed Air Energy Storage (FIP-CAES) in Reserve Tanks composed of Concentric Ring Tanks containing graduated pressures with the highest pressure in the Center Ring Tank, the lowest pressure in the Outermost Ring Tank& graduated pressures in the Intermediary Ring Tanks (Figs 7, 8). Each Concentric Ring Tank is in turn composed of Catenary Tanks (Fig 8) to minimize wall thickness, since the wall thickness of a larger tank must increase exponentially compared to the wall thickness of a smaller tank containing the same pressure, which are vertically parallel to each other (Fig 7). The ends (tops & bottoms) of the HP-CAES Concentric Catenary Ring Tanks (Fig 7) are closed by flat horizontal tank plates forming square corners with the tank sides (Figs 7, 8, 10), which are held in place by reinforced concrete (or other) block plugs (Figs 7,9, 10), in turn held in place by anchors secured by Stranded Wire Ropes (Figs 7, 9), which may be pretensioned in pipes stretching from top to bottom of 1 or more Ring Tanks or by anchors secured by the extended tank wall plates (Figs 7, 10), whichever, may be necessary according to the pressure in each respective Ring Tank. e) This MWTS Improvement combines the functions of the Transfer Valves & Regulator Valves (Fig 7, 8, 10) such that Ring Tank 1 (Outermost) is in direct communication with each of Ring Tanks 10 (Center), 9, 8, 7, 6, 5, 4, 3, & 2 by means of Bypass Lines thru Transfer Valves which are graduated to maintain a pressure differential between adjacent Ring Tanks, such that the highest pressure is in Ring Tank 10 (Center) & the pressures are reduced in graduated stages to the Outer Ring Tank in a way that each Ring Tank need support a pressure differential which may be only about 300PSI, to Ring Tank 1 from which the air is dispatched to air turbines which drive generators for electricity generation (Figs 7, 8, 11 ). f) This MWTS Improvement provides for Uncloggable Transfer Valves (Fig 7, 8, 10) wherein the valve lid (with a hinge on one side) closes against a soft seal & opens radially on the hinge, such that, as the differential pressure from the inner tank increases, the lid begins to rotate & detach incrementally from the soft seal before any chance of freeze-up, after which the lid opens as much as required by the air flow driven by the total pressure differential. g) This MWTS Improvement provides for Dispatch Valves (Fig 7, 8, 11 ), which may be Butterfly Valves, such that pressurized air may be released in seconds for the immediate dispatch of electric power. h) This MWTS Improvement provides for an Underwater Reserve Tank System (Figs 12, 13) in which compressed air, as it is produced, is received directly from the high pressure stages of the Wind Turbines, at the top (Fig 12) & forced down large Storage Tubes, pushing down the water level in the Storage Tubes according to the pressure delivered (Figs 12, 13). The heat from compression is preserved by insulating the top & sides of the Underwater Reserve Tank System, while the hot air in the Storage Tubes is insulated from the cold water at the bottom by Insulator Floats (Fig 12, 13), which rise & fall with the water level. i ) This MWTS Improvement provides for bracing & anchoring the Land Based Wind Turbines by means of Guy Stays& Guy Stay Anchors (Figs 14.
