摘要： A wind turbine has an impeller surrounded by a turbine shroud and/or an ejector shroud, wherein the turbine shroud and/or the ejector shroud include inflatable portions and/or flexible inflatable portions. In some embodiments, the turbine shroud and/or the ejector shroud include internal rib members whose shape or length can be changed to alter the characteristics of the wind turbine.

摘要： Disclosed are wind turbines comprising a turbine shroud and optionally an ejector shroud. The shrouds are segmented, or in other words have longitudinal spaces between segments. Such wind turbines have reduced drag load, particularly those loads due to off-axis wind forces.

摘要： Systems for protecting a wind turbine in high wind conditions are disclosed. A shrouded turbine may have an ejector shroud disposed adjacent and downstream of a turbine shroud. In one version, the ejector shroud can move to surround the turbine shroud. In another version, the turbine can be pivoted on a support tower to cover the intake end of the turbine and rotate the turbine about an axis at a right angle to the tower axis. In another version, the turbine is supported by a telescoping tower which may be retracted to lower the turbine in high winds. In another version, the tower sections may be connected by a pivotable connection and supported by guy wire(s) which may be lengthened to lower the upper tower section pivotally.

摘要： A fluid turbine comprises a turbine shroud, an ejector shroud, and a means for extracting energy from a fluid stream. The means for extracting energy is located in the annulus between the turbine shroud and the ejector shroud. High- energy fluid can flow through the turbine shroud to bypass the means for extracting energy. Energy is extracted from the fluid passing through the means to form a low-energy fluid stream. The high-energy fluid and the low-energy fluid can then be mixed. The turbine shroud and/or the ejector shroud has mixing lobes to increase the mixing of the two fluid streams.

摘要： A shrouded fluid turbine comprises an impeller and a turbine shroud surrounding the impeller. The inlet of the turbine shroud is flared. The shroud includes alternating inward and outward curving lobe segments along a trailing edge of the turbine shroud. The inward and outward curving lobe segments have exposed lateral surfaces, or in other words do not have sidewalls joining the inward and outward curving lobe segments. This allows for both transverse mixing and radial mixing of air flow through the turbine shroud with air flow passing along the exterior of the turbine shroud.
