Helicopters are set apart from other aircraft in a very big way: the rotors. There's the main rotor and the tail rotor. Ever ...

The pitch of a wind-turbine blade describes the angle of the blade chord to the plane of rotation. It is analogous to the way the pitch of a leadscrew determines how far its load moves with each ...

By actively managing the blade angle, operators can optimize the rotational energy from the wind, no matter the wind speed. Housed within the wind turbine pitch actuator, a hydraulic pitch ...

The pitch control monitors and adjusts the angle of the wind turbine’s rotor blades, which can measure up to 65 meters long, and thus controls the rotational speed of the turbine. Although pitch ...

By pitching the blade back and forth at different angles, speeds, and amplitudes, they generated series of 'pitch profiles'. Then, they used a computer to run a genetic algorithm, which performed ...

It doesn't require any expensive active blade-pitch control systems ... The blade is fixed to the mast at a slight upward angle. At low wind speeds, the mast tilts right over, and effectively ...
