Twist. The tips of a WT [wind turbine] blade move through the air faster than the roots in the direction of rotation, but the oncoming wind speed is similar at all points along the blade. Hence, to achieve the optimal angle of attack along its length, a WT blade is twisted so that the pitch of the blade reduces from the root to the tip. 2, record 2, English, - twist

Two theories are recognized on the operation of a propeller in converting engine shaft torque to thrust. The momentum theory deals with the energy exchange to the air mass acted upon by the propeller. The other and most commonly used concept in determining propeller performance is the blade element theory. In this theory(known as the Drzewiecki theory), each propeller blade is considered as being composed of an infinite number of airfoils(called blade elements) joined end to end, forming a shape similar to a twisted airplane wing. 3, record 4, English, - blade%2Delement%20theory

Les explications théoriques sur le fonctionnement de l'hélice peuvent être présentées de deux façons différentes : une façon synthétique où l'on jette un regard d'ensemble sur les phénomènes auxquels donne lieu son action. Cette méthode a l'avantage de convenir aussi à la propulsion par réaction. (...) La seconde méthode, méthode analytique appelée aussi méthode des sections élémentaires, consiste à décomposer l'hélice en ses éléments et à étudier le mode d'action de chacun d'eux. 1, record 4, French, - m%C3%A9thode%20des%20sections%20%C3%A9l%C3%A9mentaires
