C. Nacelle The nacelle is the fiberglass housing around the main body of the machine. It contains the main structural “backbone” of the turbine (called the mainframe), the rectifier, the slip-ring assembly, the yaw bearings, and the tower mount. The yaw bearings allow the wind turbine to freely pivot around the top of the tower so that the rotor will face into the wind. - Page 6 AutoFurl was used in the very first wind sys- the aerodynamic forces acting on the blades tem produced by Bergey Windpower in 1980 and cause a thrust force pushing back on the rotor. in every unit produced since.
