摘要： A fluid dynamic body having a trailing edge with a pattern formed thereon, the pattern can include a plurality of smoothly surfaced adjacent members with respective interstices therebetween, wherein at least one of the interstices completely contains a porous barrier. In some embodiments, the porous barrier can obstruct fluid flow through the respective interstice between a first surface of the fluid dynamic body on a first side of the trailing edge and a second surface of the fluid dynamic body on a second side of the trailing edge. This helps to reduce noise produced at the trailing edge. In some embodiments, the fluid dynamic body is a wind turbine blade or an air-engine blade.

摘要： Methods of manufacturing rotor blade components for a wind turbine and rotor blade components produced in accordance with such methods are disclosed. In one embodiment, the method generally includes providing a mold of the rotor blade component; coating at least a portion of an interior surface of the mold with an elastomeric material; inserting impletion material within the mold so as to at least partially reduce an open internal volume within the mold; inserting a foam material within the mold; and, removing the rotor blade component from the mold, wherein the elastomeric material forms a cover skin around at least a portion of the rotor blade component. In an alternative embodiment, the method includes providing at least one support member defining a profile for the rotor blade component on a mold surface; coating at least a portion of the support member with an elastomeric material; and, allowing the elastomeric material to cure on the mold surface so as to form the rotor blade component.

摘要： A cooling-arrangement is provided. The arrangement for cooling includes a device and a heat exchanger. The device is coupled with the heat exchanger in a way, that heat, which is generated inside the device, is transferred from the device to the heat exchanger. The heat exchanger is at least partly arranged into an ambient airflow. The heat exchanger is constructed in a way that the heat is transferred from the heat exchanger into the ambient airflow. The heat exchanger contains a suction side and a pressure side, which are arranged and constructed in a way that the ambient air, which passes by close to the sides, is accelerated for an improved heat transfer.

摘要： A composite component (130) such as a shear web for a wind turbine blade is described. The component comprises a moulded laminate (44) formed from one or more fibrous layers (40) integrated by resin and defining a laminate edge (48). An edging strip (60) is located adjacent to the laminate edge (48) and is integrated with the laminate. In a particular example, the edging (60) is made from closed-cell foam. Accordingly, resin does not permeate into the bulk of the edging (60) during the moulding process. After the moulding process, a portion (60a) of the edging (60) is removed to reveal an exposed, substantially resin-free surface of the edging which defines a safety edge (64) of the component.
