    • An aerodynamic brake assembly for use with an airfoil such as the blade of a wind turbine rotor comprises deployable upper and/or lower spoiler plates incorporated in or attached to the airfoil. The spoiler plates can deploy under the influence of centrifugal forces when the rotating airfoil or rotor blade reaches a pre-determined rotational speed. The aerodynamic brake assembly may be integrated within the airfoil or attached to the tip of the airfoil such that, when not deployed, the upper and lower spoiler plates have a profile that approximately conforms to the profile of the part of the airfoil to which it the brake assembly is attached. Thus in a non-deployed state, the spoiler plates have a non-detrimental effect on the performance of the airfoil, and may even contribute to its aerodynamic lift properties. A weighted arm linked to the spoiler plate mechanism can be held in position electromagnetically or by solenoid, until an electrical signal from a controller causes it to release, leading to deployment of the spoiler plates. Failsafe deployment of the spoiler plates can occur either upon loss of power to the mechanism, or when the centrifugal force associated with an overspeed condition of the rotor overcomes the holding force of the electromagnet or solenoid.
    • 用于诸如风力涡轮机转子叶片的机翼的空气动力学制动组件包括结合在翼型件中或连接到翼型件上的可展开的上部和/或下部扰流板。 当旋转翼型或转子叶片达到预定转速时,扰流板可在离心力的作用下展开。 空气动力学制动器组件可以集成在翼型内或附接到翼型的末端,使得当未展开时,上部和下部扰流板具有近似符合翼型部分的轮廓的轮廓, 制动器组件被连接。 因此,在未部署状态下,扰流板对翼型的性能具有非有害影响,并且甚至可能有助于其空气动力升力特性。 连接到扰流板机构的加权臂可以通过电磁或螺线管保持在位置,直到来自控制器的电信号使其释放,导致扰流板的展开。 扰流板的故障安全部署可能在机构失去动力时发生,或者当与转子的超速状态相关联的离心力克服了电磁铁或螺线管的保持力时。
