Abstract: Wind turbine blade comprising a shape modifiable airfoil section that extends both chordwise and spanwise and has a not modified default shape, a conduit that extends from the inside of the blade towards the outside of the blade, and an outer part comprising a flow regulator that is located at the shape modifiable airfoil section and blocks the conduit when the shape modifiable airfoil section presents its default shape, and does not block the conduit when the shape modifiable airfoil section presents a modified shape. In the latter situation the conduit is opened to the outside of the blade and a device for exchanging a fluid between the inside and the outside of the blade is thus defined.
Abstract translation: 风力涡轮机叶片包括形状可修改的翼型部分，其同时沿翼展方向和翼展方向延伸并且具有未改变的默认形状，从叶片的内部朝向叶片的外侧延伸的管道，以及包括流量调节器的外部部件， 位于形状可修正的翼型部分，并且当形状可修改的翼型部分呈现其默认形状时阻塞导管，并且当形状可修改翼型部分呈现改变形状时不阻塞导管。 在后一种情况下，导管打开到叶片的外部，因此限定了用于在叶片的内部和外部之间更换流体的装置。

Abstract: Wind turbine blades comprising one or more deformable trailing edge sections having a multistable sheet comprising a plurality of bistable elements, each bistable element having two stable positions, wherein the multistable sheet is attached in a cantilever manner to a structural portion of the blade and extends in a chordwise direction, and the multistable sheet is connected to a skin of the blade such that upon changing one or more bistable elements from one stable position to the other stable position a shape of the trailing edge section changes. The application further relates to wind turbines comprising such blades and methods of controlling loads on the blades.

Abstract: Wind turbine blade comprising at least one deformable trailing edge section having a plurality of actuators consecutively arranged substantially downstream from one another and a control system for controlling the actuators, wherein a downstream end of one actuator is connected by a substantially rigid link with an upstream end of the next actuator and the plurality of actuators comprises an upper actuator being mounted above a chord line of the blade section and a lower actuator being mounted below a chord line of the blade section. Wind turbines comprising such a blade and methods of controlling loads on a wind turbine blade are also described.
