In the late 1940s and 1950s, the US military wanted an aircraft that could take off like a helicopter but fly fast enough to ...

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 ...

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 ...

For future NASA missions to Mars, this new helicopter vehicle will be key to surveying the planet's surface for all sorts of ...

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, ...

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 ...

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 ...

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 ...

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 ...

On June 18, 1986, tourists were flying over the Grand Canyon on two separate sightseeing tours: one in a Twin Otter plane and ...
