Abstract: One or more air nozzles (31) create respective air jets (34) angled radially from a blunt trailing edge (22) of a wind turbine blade (20A-G). The jets create and maintain a radially flowing airstream (36) along the trailing edge that extinguishes vortex shedding (28). This reduces drag and noise, thus allowing blades to have an extensive blunt trailing edge, which increases resistance to buckling, thus enabling longer blades. The jets may be supplied by airflow from an air intake in a blade chamber (44), or a ram air intake (40), or a compressor (54). Each nozzle may be individually metered (60) and/or individually or group valved (58) to provide a particular airflow to each nozzle relative to the other nozzles. Overall airflow to the nozzles may be modulated responsive to ambient conditions, and may be further cyclically modulated responsive to an azimuth of the blade

Abstract translation: 一个或多个空气喷嘴（31）产生与风力涡轮机叶片（20A-G）的钝的后缘（22）径向成角度的相应的空气射流（34）。 射流沿着后缘产生和保持径向流动的空气流（36），其消除涡流脱落（28）。 这减少了阻力和噪音，从而允许叶片具有广泛的钝的后缘，这增加了抵抗弯曲的能力，从而实现更长的叶片。 喷气机可以由来自叶片室（44）或冲压进气口（40）或压缩机（54）中的进气口的气流供应。 每个喷嘴可以单独地计量（60）和/或单独地或分组阀（58）以相对于其它喷嘴向每个喷嘴提供特定的气流。 可以响应于环境条件调节到喷嘴的总体气流，并且可以响应于叶片的方位进一步循环调制

Abstract: A blade for a wind turbine includes a device for causing air at an increased velocity and/or pressure to escape from exit openings in the blade, thereby to apply a force. Pressure and diameter adjustable valves may be provided at each exit opening or orifice to allow the air to exit from the blade only when the air pressure within the blade exceeds a preset level. Also disclosed is the provision of valves at the exit openings or orifices on an opposite edge of the blade that allows air to escape from the blade to slow down but not stop rotation of the blade when a dangerous wind condition is detected.
