Siemens has created a special mechanism for mounting its 75-meter-long rotor blades for offshore wind farms. The lifting system makes assembly work safer and lets construction take place at higher ...

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 ...

New wind turbines installed across the United States in 2023 arrived with rotors averaging 133.8 meters in diameter, a span ...

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, ...

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 ...

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 ...

March 27, 2009 Can you imagine a world full of large, relatively quiet rotorcraft making short hops between cities such as New York and Washington, carrying as many as 100 passengers at a time in ...

DLR energy researchers have manufactured the first innovative rotor blade (Smartblade) that adapts to wind conditions using bending torsion coupling In the coming weeks, the rotor blade will undergo ...

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 ...
