The toroidal propeller allows a small multirotor unpiloted aircraft, or drone, to operate more quietly than current drones that use propeller forms unchanged since the beginning of aviation. [It] consists of two blades looping together so that the tip of one blade curves back into the other. This closed-form structure minimizes the drag effects of swirling air tunnels... created at the tips of blades and strengthens the overall stiffness of the propeller. These features reduce the propeller's acoustic signature. 2, record 1, English, - toroidal%20propeller

L'hélice toroïdale permet à un drone de fonctionner plus silencieusement que les drones possédant des hélices qui ont un profil n'ayant jamais été modifié depuis les tous débuts de l'aéronautique. [Elle] se compose de deux pales s'enroulant ensemble de sorte que l'extrémité d'une pale se recourbe dans l'autre. Cette structure de forme fermée minimise les effets de traînée des tunnels d'air tourbillonnants [...] créés au bout des pales et renforce la rigidité globale de l'hélice.

The term feathering refers to the operation of rotating the blades of a propeller to an edge-to-the-wind position for the purpose of stopping the rotation of the propeller whose blades are thus feathered and to reduce drag. Therefore, a feathered blade is an approximate in-line-of-flight position, streamlined with the line of flight. Some, but not all, propellers can be feathered. Feathering is necessary when an engine fails or when it is desirable to shut off an engine in flight. The pressure of the air on the face and back of the feathered blade is equal, and the propeller will stop rotating. If it is not feathered when its engine stops driving it, the propeller will "windmill" and cause drag. 3, record 6, English, - feathering

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 8, French, - h%C3%A9lice%20%C3%A0%20pas%20variable

A propeller the blades of which have been rotated so that the leading and trailing edges are nearly parallel with the aircraft flight path to stop or minimize drag and engine rotation. 2, record 17, English, - feathered%20propeller
Record number: 17, Textual support number: 1 CONT
The term "feathering" refers to the operation of rotating the blades of a propeller to an edge-to-the-wing position for the purpose of stopping the rotation of the propeller whose blades are thus feathered and to reduce drag. Therefore, a feathered blade is in an approximate in-line-of-flight position, streamlined with the line of flight. Some, but not all, propellers can be feathered. Feathering is necessary when an engine fails or when it is desirable to shut off an engine in flight. The pressure of the air on the face and back of the feathered blade is equal, and the propeller will stop rotating. If it is not feathered when its engine stops driving it, the propeller will "windmill" and cause drag. Another advantage of being able to feather a propeller is that a feathered propeller creates less resistance(drag) and disturbance to the flow of air over the wings and tail of the airplane. 3, record 17, English, - feathered%20propeller

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 23, English, - feather%20the%20propeller

[The Allison A6441FN-606 and 606A turbopropeller has the two following features :] Mechanical Low-Pitch Stop(MLPS). The mechanical low-pitch stop is designed to prevent the inadvertent entry of the blades into the beta range during flight in the event of propeller-control-system malfunction. The MLPS with a setting of 18. 25 to 18. 5 ° "backs up" the normal hydraulic low-pitch stops. Hydraulic Low-Pitch Stop(HLPS). The hydraulic low-pitch stop is designed to prevent the propeller hydraulic governor from decreasing the blade angle into the beta range during governing operation. The HLPS has a setting of 20 ° blade angle from 30 to 68 ° coordinator. From 68 to 90 ° coordinator HLPS is scheduled from 20 to approximately 31. 5 ° blade angle. This scheduling is called beta follow-up and means that the propeller pitch cannot decrease below 20 or 30 ° during constant-speed operation controlled by the governor. 4, record 34, English, - flight%20fine%20pitch%20stop

A true pitch propeller is one that makes use of the blade-element theory. Each element(section) of the blade travels at a different rate of speed, that is, the tip sections travel faster than the sections close to the hub. When the elements(sections) are arranged so that each is set at the proper angle to the relative airstream, they all advance the same distance during any single revolution of the propeller. 1, record 44, English, - true%20pitch%20propeller

Si l'on veut avoir une hélice dont toutes les sections possèdent le même pas H, il suffit de réaliser la condition r tg[alpha]=constante=k (où alpha correspond à l'angle de calage] (...) L'hélice à pas constant ainsi définie n'est plus utilisée à l'heure actuelle; en effet, la présence du fuseau moteur réduit la vitesse de l'air au voisinage du moyeu, ce qui se traduit par la nécessité de réduire le pas dans cette région afin d'obtenir un rendement meilleur. Dès lors, il est nécessaire de définir un "profil de référence" afin de caractériser une telle hélice. 3, record 44, French, - h%C3%A9lice%20%C3%A0%20pas%20constant

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 45, 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 45, French, - m%C3%A9thode%20des%20sections%20%C3%A9l%C3%A9mentaires
