Wind turbines are growing bigger and bigger – the diameter of their rotor blades could soon reach 180 meters. But that creates a need for larger test rigs capable of accommodating the blades for load ...

Wind turbines have a design life of 20 years. The rotor blades must be regularly inspected at least once every four years to verify their structural integrity. This type of work is performed by ...

The turbine does not have a rotor hub; it instead features an open generator, which looks like a bicycle wheel. Each of the three pitching blades is mounted to an “A-frame” blade support structure ...

Oh, those humpback whales and their weird fins. First, they inspired more efficient wind turbines. Next, their unique qualities were copied by undersea turbines used to harness tidal flow energy. Now, ...

Siemens has developed the world's longest wind turbine rotor blades and is due to install them off the coast of Denmark by autumn 2012. The 75-metre-long rotors will fit in nicely with the local ...

Six rotor blades have been equipped with around 1500 sensors for the two wind turbines at DLR's Wind Energy Research Farm. These high-tech rotor blades have now been extensively tested by the DLR team ...

UAVOS, a leader in UAS and stratospheric programs, reports the completion of a new production run of advanced composite main rotor blades tailored for unmanned helicopter platforms. Composite rotor ...

Tomorrow's wind turbines will have even larger and lighter rotor blades. This will make them even more efficient. Six rotor blades have been manufactured for DLR's Wind Energy Research Farm and ...

WASHINGTON — The U.S. Army is dealing with excessive rotor blade vibrations in its latest variant of the Boeing-manufactured Chinook cargo helicopter as it heads into a limited-user test during the ...
