A semi-rigid rotorhead does not have individual flapping or drag hinges but provides for flapping and lag motion through gimbal mounting. [3] A common example of a semi-rigid rotor is a teetering rotorhead found on the Robinson family of helicopters.
An example of a wind turbine, this 3 bladed turbine is the classic design of modern wind turbines Wind turbine components : 1-Foundation, 2-Connection to the electric grid, 3-Tower, 4-Access ladder, 5-Wind orientation control (Yaw control), 6-Nacelle, 7-Generator, 8-Anemometer, 9-Electric or Mechanical Brake, 10-Gearbox, 11-Rotor blade, 12-Blade pitch control, 13-Rotor hub
A nacelle / n ə ˈ s ɛ l / is a cover housing that houses all of the generating components in a wind turbine, including the generator, gearbox, drive train, and brake assembly. [1]
Rotor hub and pitch bearing without mounted rotor blades. The pitch bearing, also named blade bearing, is a component of modern wind turbines which connect the rotor hub and the rotor blade. [1]

The swashplate was first tested in 1907 by brothers Jules and Paul Cornu.They obtained a patent for the device (French Patent No. 398,545, June 7, 1909). [1] Although its principle is also found in earlier patents by other screw inventors.
The helicopter rotor is powered by the engine, through the transmission, to the rotating mast. The mast is a cylindrical metal shaft that extends upward from—and is driven by—the transmission.
