The Kellett XR-8 (later redesignated XH-8) was a helicopter built in the United States during World War II.It was a two-seat machine intended to demonstrate the feasibility of a twin-rotor system and, while it accomplished this, it also demonstrated a number of problems that prevented further development of this particular design.
The passive yaw systems utilize the wind force in order to adjust the orientation of the wind turbine rotor into the wind. In their simplest form these system comprise a simple roller bearing connection between the tower and the nacelle and a tail fin mounted on the nacelle and designed in such a way that it turns the wind turbine rotor into ...
The widespread use of their distinctive wind pumps on ranches throughout the arid plains and deserts of the United States has made their design a quintessential image of the American West. The company also manufactured galvanized steel fire lookout towers including a "7 x 7" model which supported a 7-by-7-foot (2.1 m × 2.1 m) steel cab at ...
Counter-rotating wind turbines Light pole wind turbine. Unconventional wind turbines are those that differ significantly from the most common types in use.. As of 2024, the most common type of wind turbine is the three-bladed upwind horizontal-axis wind turbine (HAWT), where the turbine rotor is at the front of the nacelle and facing the wind upstream of its supporting turbine tower.
λ is a characteristic of each specific windmill, and for a Savonius rotor λ is typically around unity. For example, an oil-barrel sized Savonius rotor with h= 1 m and r= 0.5 m under a wind of v= 10 m/s, will generate a maximum power of 120 W and a maximum angular speed of 20 rad/s (190 revolutions per minute).
Contrary to the old windmill concept, the modern yaw bearings support the nacelle also from the top [clarification needed] thus restraining the nacelle from being rotated by the Y-axis due to the moments induced by the upper half of the rotor sweep disk and the X-axis due to the torque of the drive train (i.e. rotor, shaft, generator, etc. ).

The yaw system is located between the wind turbine nacelle and tower. The yaw drive is an important component of the horizontal axis wind turbines ' yaw system . To ensure the wind turbine is producing the maximal amount of electric energy at all times, the yaw drive is used to keep the rotor facing into the wind as the wind direction changes.
