Hill Helicopters engineered composite main rotor blades using a novel single-cure manufacturing process for stiffness and ...

It incorporates strips of fiber optic sensors that are mounted along the length of each rotor blade. As the helicopter flies, those sensors measure the strain being placed on the blade, along with any ...

Even the best helicopters are loud, rickety gas guzzlers, and a big reason for that is the rotors themselves. As each blade cuts the air, it creates a turbulent wake; the next blade passes through ...

A research team from the Kiel University of Applied Sciences (HAW Kiel) is developing a process together with Nuebold Yachtbau GmbH that can reduce the expensive production of rotor blades for small ...

Airbus Helicopters in the UK is exploring future activities to follow on from a four-year research project, in conjunction with Cranfield University, that has shown strong potential for advancing the ...

Wind turbines deliver environmentally friendly electricity. Yet the fiber-reinforced plastics often used in very large rotor blades are almost impossible to recycle. Not so with steel blades: since ...

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 ...

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 ...
