Abstract
Un profil aérodynamique semi-annulaire est conçu conjointement avec une pale de rotor de turbine à fluide pour fournir une vitesse de pointe de rotor accrue, un coefficient de puissance accru, un cisaillement de vent réduit et un bruit réduit. Une pale de rotor à double ailette en combinaison avec un profil aérodynamique semi-annulaire augmente les avantages mentionnés ci-dessus en augmentant la surface de pointe de pale de rotor qui est en contact avec la zone de vitesse de fluide accrue sur le profil aérodynamique semi-annulaire.
