A demonstrator wind turbine blade swaps its worn plant fiber leading edge instead of scrapping the whole structure, cutting ...

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 ...

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 ...

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 ...

Offshore wind turbines are becoming ever larger, and the transportation, installation, disassembly and disposal of their gigantic rotor blades are presenting operators with new challenges. Now ...

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 ...

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 ...

Specially shaped helicopter rotor blades with a kink at the outer part make it possible to reduce the radiating annoying rotor noise [1]. Against this background, the aeroelastic behaviour together ...
