Downwind and upwind wind turbines
WebJul 10, 2014 · In addition, the upwind turbines need a yaw control mechanism to keep the rotor facing the wind. Downwind turbines, on the other hand, do not typically need a yaw control mechanism if the rotor and nacelle have a suitable design to make the nacelle passively align with the wind. WebAdj.1.downwind – towards the side away from the wind. A – leeward – on the side away from the wind; “on the leeward side of the island”. Adv.1.downwind- with the wind; in the …
