Definitions

  • the shroud second rigid structural member can be shaped to provide the turbine shroud with a plurality of lobes.
  • the shroud inflatable member is shaped to provide a plurality of lobes around a trailing edge thereof.
  • the wind turbine may further comprise an ejector shroud disposed concentrically about the turbine shroud, the ejector shroud comprising an inflatable member.
  • the ejector shroud may further comprise a first rigid structural member connected to the ejector inflatable member.
  • the ejector first rigid structural member can comprise a hollow interior into which the ejector inflatable member can be inserted.
  • the ejector first rigid structural member may also define a leading edge of the ejector shroud.
  • the ejector shroud may further comprise a second rigid structural member connected to the ejector inflatable member opposite the ejector first rigid structural member, the second rigid structural member defining a trailing edge of the ejector shroud.
  • the ejector second rigid structural member can be shaped to provide the ejector shroud with a plurality of lobes.
  • FIGURE 4 is a perspective view of a fourth exemplary embodiment of the present disclosure.
  • FIGURES 8A-8C are side views of various internal rib members which can be used in exemplary embodiments of the present disclosure.
  • FIGURES 8D-8E show wind turbines before and after the use of various internal rib members such as those shown in FIGURES 8A-8C.
  • FIGURE 1 is a perspective view of a first embodiment of a wind turbine of the present disclosure, in a form also known as a mixer-ejector wind turbine (MEWT).
  • the MEWT is a new type of wind turbine that uses a shrouded impeller, prop, or rotor/stator to improve the efficiency of a wind turbine such that more power may be extracted for a turbine having the same area than other current types of wind turbines.
  • the MEWT accomplishes this by drawing air from a larger area than the most common type of wind turbine, the horizontal-axis wind turbine (HAWT).
  • HAWT horizontal-axis wind turbine
  • a wind turbine can theoretically capture at most 59.3% of the potential energy of the wind passing through it, a maximum known as the Betz limit.
  • the impeller and the motor/generator are contained within the turbine shroud.
  • the turbine shroud 30 may also have mixer lobes 40 around an outlet or exhaust end of the shroud.
  • the mixer lobes are generally uniformly distributed around the circumference of the exhaust end.
  • the mixer lobes generally cause the exhaust end 36 of the turbine shroud, where air exits, to have a generally peak-and-valley shape about its circumference. Put another way, the lobes 40 are located along the trailing edge 38 of the shroud.
  • the turbine 10 also comprises an ejector shroud 50, which is engaged with the turbine shroud.
  • the ejector shroud comprises a ringed airfoil 54, or in other words is approximately cylindrical and has an airfoil shape, with the airfoil configured to generate relatively higher pressure within the ejector (i.e. between the turbine shroud 30 and the ejector shroud 50) and relatively lower pressure outside the ejector shroud 50.
  • the ejector shroud may also have mixer lobes 60, in which case the wind turbine is a mixer-ejector wind turbine.
  • the mixer lobes generally cause the exhaust end of the ejector 56, where air exits, to have a generally peak-and-valley shape about its circumference. Put another way, the mixer lobes are located along the trailing edge 58 of the ejector shroud 50.
  • the ejector shroud 50 has a larger diameter than the turbine shroud 30.
  • the turbine shroud 30 engages the ejector shroud 50.
  • the exhaust end 36 of the turbine shroud fits within the intake end 52 of the ejector shroud, or the intake end 52 of the ejector shroud surrounds the exhaust end 36 of the turbine shroud.
  • the turbine shroud 30 and ejector shroud 50 are sized so that air can flow between them.
  • the ejector shroud 50 is concentrically disposed about the turbine shroud 30 and is downstream of the shroud 30.
  • the impeller 20, turbine shroud 30, and ejector shroud 50 all share a common axis, i.e. are coaxial to each other.
  • FIGURE 2 shows another exemplary embodiment of the turbine.
  • the turbine 110 has an impeller 120, turbine shroud 130, and an ejector shroud 150.
  • the turbine shroud 130 comprises a first rigid structural member 132 connected to an inflatable member 134.
  • the first rigid member 132 defines the leading edge 136 of the shroud 130.
  • the shroud inflatable member 134 is shaped to provide a plurality of lobes 140 around the trailing edge 138 of the turbine shroud.
  • the ejector 150 comprises a first rigid structural member 152 connected to an inflatable member 154.
  • the ejector inflatable member 324 is configured so that upon partial inflation, the area 330 circumscribed by the trailing edge 332 of the ejector inflatable member is less than the area circumscribed by the leading edge 334 of the ejector shroud.
  • the area circumscribed by the leading edge refers to the entire area defined by the leading edge, not only the annular area between the turbine shroud 310 and ejector shroud 320.
  • FIGURES 7A-7C show various stages of the construction of other exemplary embodiments of a shroud and/or ejector useful for a wind turbine of the present disclosure.
  • the impeller is not shown in these figures.
  • the combination shroud/ejector 390 comprises a circular member 400 and a plurality of shroud first rib members 410 which together define an intake end 402 and an exhaust end 404 for the turbine shroud.
  • the circular member 400 and the plurality of shroud first rib members 410 are then covered by an exterior film material 406 to complete the turbine shroud.
  • the exhaust end 404 of the turbine shroud may have a smaller area than the intake end 402.
  • first internal rib 460 can be considered a one-piece combination of shroud first rib member 410 and ejector first rib member 430 while second internal rib 470 can be considered a one-piece combination of shroud second rib member 440 and ejector second rib member 450.
  • FIGURES 8A-8C are side views of various embodiments of internal ribs suitable for use in various embodiments as shown in FIGURES 7A-7C.
  • the rib 500 comprises an arcuate member 510 and a transverse member 520 integrally formed together to form a generally rigid rib.
  • the members are generally lightweight and can be considered as beams 502 joined together by struts 504.
  • the arcuate member 510 defines the shape of the turbine shroud, while the transverse member 520 defines the shape of the ejector shroud.
  • the solid outline shows a shortened or linear position, while the dashed outline shows a lengthened or angled position.
  • This ability to change shape allows the overall skeleton of the turbine shroud or ejector shroud to move / change shape as well.
  • the stationary member 530 and actuated member 540 are joined together at both the top and bottom edges 506, 508 by a sleeve or linear motion member 560 which, together with the actuator 570, changes the length of the rib 500.
  • the inflatable members may also be partially or completely stiffened through the use of reactive polymer infusion through vacuum assisted resin transfer molding (VARTM) or the curing of previously impregnated polymers such as unsaturated polyesters, epoxy , acrylates or urethanes that are cured through radiation, free radical initiation, or crosslinking with isocyanate.
  • VARTM vacuum assisted resin transfer molding
