摘要： An unevenly loaded turbine rotor blade is disclosed herein, the blade including a power-extracting region adapted for radially-varied (relative to the axis of rotation) power extraction per mass flow rate. The pitch and/or shape of the airfoil at a first radial position may be configured, so that power extraction per mass flow rate at the first radial position is different than power extraction per mass flow rate at a second radial position. Thus, the power-extracting region may be advantageously configured to take advantage of a non-uniform flow profile across a rotor plane such as may be induced using a shrouded turbine.
摘要翻译： 本文公开了一种不均匀装载的涡轮转子叶片，该叶片包括适于沿每个质量流量径向变化（相对于旋转轴线）功率提取的功率提取区域。 在第一径向位置处的翼型件的间距和/或形状可以被配置为使得在第一径向位置处的每质量流量的功率提取不同于在第二径向位置处的每质量流量的功率提取。 因此，功率提取区域可以有利地构造成利用横跨转子平面的不均匀流动分布的优点，例如可以使用带罩的涡轮机来感应。

摘要： A Mixer/Ejector Wind Turbine (“MEWT”) system is disclosed which routinely exceeds the efficiencies of prior wind turbines. Unique ejector concepts are used to fluid-dynamically improve many operational characteristics of conventional wind/water turbines for potential power generation improvements of 50% and above. Applicants' preferred MEWT embodiment comprises: an aerodynamically contoured turbine shroud with an inlet; a ring of stator vanes; a ring of rotating blades (i.e., an impeller) in line with the stator vanes; and a mixer/ejector pump to increase the flow volume through the turbine while rapidly mixing the low energy turbine exit flow with high energy bypass wind flow. The MEWT can produce three or more time the power of its un-shrouded counterparts for the same frontal area, and can increase the productivity of wind farms by a factor of two or more. The same MEWT is safer and quieter providing improved wind turbine options for populated areas.

摘要： A shrouded wind turbine includes a shroud with an exterior surface that includes a smooth outer surface. The smooth outer surface is large enough that additional devices, particularly advertising displays or solar panels, can be mounted to the shroud to more efficiently use available surface area, both on the wind turbine itself and on the footprint of the wind turbine.

摘要： A mixer-ejector wind turbine uses an ultracapacitor system to store power from the variable generation of power by a permanent magnet generator. The system takes advantage of the MEWT area ratio, the higher velocity at the outer radius of the turbine, and the ability of the ultracapacitor system to store almost all of the input charge.

摘要： One or more variable pitch airfoils in fluid communication with a rotor of a fluid turbine can control the amount of energy directed to the rotor, and further control the amount of energy generated by the turbine. Varying the pitch of the airfoils may provide a means of controlling the power output of a fluid turbine without the need to control the pitch of the rotor blades, and may further provide a means of mitigating the effects of wind shear on the rotor. Variable pitch airfoils may also include a means of controlling the active power, reactive power and SCADA, of a group of fluid turbines.

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： Example embodiments are directed to shrouded fluid turbines that include a turbine shroud and a rotor. The turbine shroud includes a an inlet, an outlet and a plurality of mixer lobes circumferentially spaced about the outlet. The rotor can be disposed within the turbine shroud and downstream of the inlet. The rotor includes a hub and at least one rotor blade engaged with the hub. The shrouded fluid turbines further include a passive yaw system for regulating a yaw of the shrouded fluid turbine. The shrouded fluid turbine defines a center of gravity and a center of pressure.
