A vertical-axis wind turbine whose rotor runs through an aerodynamic lift exerted on its blades.  4, record 1, English, - lift%2Dtype%20wind%20turbine

Record number: 1, Textual support number: 1 OBS

Wind turbine blades are essentially airfoils. When air flows past the blade, a wind speed and pressure differential is created between the upper and lower blade surfaces. The pressure at the lower surface is greater and thus acts to "lift" the blade. When blades are attached to a central axis, like a wind turbine rotor, the lift is translated into rotational motion.  5, record 1, English, - lift%2Dtype%20wind%20turbine

Le capteur à portance est beaucoup plus efficace que le capteur à traînée [...]. La portance étant dirigée vers l'avant du profil, elle tend à faire tourner l'hélice normalement autour de son axe horizontal [...]. Les profils aérodynamiques ont des formes qui permettent d'obtenir des rendements élevés. Les éoliennes à portance utilisent ce type de profil : il est évident que l'inconvénient de ce type d'éolienne est leur plus grande difficulté de réalisation.  2, record 2, French, - capteur%20%C3%A0%20portance
