The blades of a variable-pitch propeller are attached to a mechanism in the hub that rotates the entire blade about an axis that runs along the length of the blade … This allows the blade pitch to be varied continuously by the pilot to maintain optimum efficiency at any airspeed. 4, record 2, English, - variable%2Dpitch%20propeller

Variable-pitch propellers include propellers whose pitch can be set up automatically and propellers whose pitch can be set up manually (i.e. by pilot’s operation). Although "controllable-pitch propeller" can be a synonym of "variable-pitch propeller," most authors consider that controllable-pitch propellers only include propellers whose pitch can be changed manually. 5, record 2, English, - variable%2Dpitch%20propeller

Au début, les hélices étaient à pales fixes, réglées pour la vitesse maximale, et ayant un très mauvais rendement au décollage, où une grande puissance est nécessaire. Aujourd'hui, on n'emploie plus que des hélices à pas variable. Dans ces hélices, les pales peuvent tourner autour de leur axe longitudinal (perpendiculaire à l'arbre moteur) pour prendre une inclinaison variable; elles sont actionnées par un moteur électrique ou un piston hydraulique par l'intermédiaire d'un système de leviers ou d'engrenages et de crémaillères, le tout situé dans le carter de l'hélice. L'inclinaison peut être commandée soit à la main, soit automatiquement en fonction de la vitesse du moteur et de la résistance de l'air sur les pales, de manière que le rendement soit toujours optimal. 4, record 2, French, - h%C3%A9lice%20%C3%A0%20pas%20variable

In other small machines the centrifugal force on the blades as the rotational speed rises, is made to change their pitch. The blade fixing at the hub may have a spiral socket so that the blades changes pitch as i is pulled radially outwards by this force or, alternatively, the blade spindle may be bent near the hub so that the centre of gravity of the blade lies off the axis of rotation. Pitch changing with a fly-ball governor is used in the small Winpower machines. 1, record 3, English, - pitch%20changing

Sur le quart de tour suivant les deux pales reprennent leur incidence équivalente, un quart de tour de plus et de nouveau les incidences se différencient et ainsi de suite : c'est le pas cyclique.

The two principal means of limiting rotor power in high operational wind speeds-stall regulation and pitch regulation... Stall regulated machines require speed regulation. As wind speed increases, providing the rotor speed is held constant, flow angles over the blade sections... The blades become increasingly stalled and this limits power to acceptable levels without any additional active control. For this to work, the speed of the WT [wind turbine] rotor must be held essentially constant and this is achieved through the connection of the electric generator to the grid. 4, record 20, English, - stall%20regulation

The tail rotor assembly is made up of a mast, hub, two scissors assemblies, four pitch control rods, slider, spider, four dampers, four blades and control(extension) rod.... The variation of the collective pitch of the blades for the thrust control is possible due to a translational movement(inwards and outwards) of the four pitch control rods. The spider-slider assembly rotates together with the hub-blades system and translates together with the extension rod, which is moved by a servoactuator system. The two scissors assemblies keep the spider-slider assembly rotating together with the hub. The dampers have the function of damping the lag movement. 2, record 26, English, - spider

A feathering propeller can alter the pitch of the blades up to almost 90 degrees. That is, the blade pitch is changed so that they have their leading edge pointing right into the direction of flight, offering minimum resistance to the airflow. This mode allows the propeller rotation to be stopped, without adding excessive drag to the aircraft. Feather may be used to improve the performance of the aircraft after the failure of an engine, but more usually in light aircraft it is used in motor glider applications. 3, record 28, English, - feather%20the%20propeller

To achieve control of power captured above rated wind speed, the blades are carefully designed so that they progressively stall starting at the blade root and moving out towards the tip as the wind speed increases further.
