Record 1 2018-03-14

English

Subject field(s)
  • Electric Rotary Machines - Types
  • Wind Energy
DEF

A vertical-axis wind turbine that uses a wind vane to mechanically orient a blade pitch change mechanism.

CONT

Vertical Axis Turbines. Vertical-axis wind turbines come in a variety of shapes and sizes: the most common type are the Darrieus or egg beater, the Savonius or S-rotor, and the cyclo-turbine. Some machines incorporate features of more than one design.

French

Domaine(s)
  • Machines tournantes électriques - types
  • Énergie éolienne
DEF

Éolienne à axe vertical qui utilise une girouette afin d'effectuer mécaniquement une modification du réglage de l'angle des pales.

CONT

G.F.M. Darrieus [...] prit un brevet américain en décembre 1931 concernant ses machines. Il est remarquable de voir qu'il n'a pas seulement inventé le batteur à œufs éolien mais aussi la machine à pales verticales droites et orientables [...]. Cette dernière [...] est maintenant commercialisée sous le nom de «gyromill».

Record 4 2009-03-23

English

Subject field(s)
  • Couplings (Mechanical Components)
  • Electric Rotary Machines - Types
  • Wind Energy
DEF

A blade pitch-control mechanism designed for 1930's battery-charging wind turbines that uses centrifugal force to act on the blades instead of heavy weights as on classic Watt governors, to change the blade pitch.

French

Domaine(s)
  • Accouplements (Composants mécaniques)
  • Machines tournantes électriques - types
  • Énergie éolienne
DEF

Mécanisme de régulation du pas de pale d'une éolienne pour la recharge de batteries qui fait appel à la force centrifuge pour actionner les pales elles-mêmes plutôt qu'à des contre-poids comme pour un régulateur de Watt classique.

Spanish

Record 5 2004-07-28

English

Subject field(s)
  • Helicopters (Military)
CONT

The purpose of the pitch horn is to give the feathering pitch change mechanism(cyclic/swashplate) a place to attach to the blade. By sticking out from the blade, the pitch horn works as a lever, decreasing the force it takes to change the angle of the blade.

OBS

pitch horn: term officialized by the Aeronautical Terms Standardization Committee (ATSC) - Helicopters.

PHR

Blade, rotor blade pitch horn.

French

Domaine(s)
  • Hélicoptères (Militaire)
OBS

Record 6 1987-08-06

English

Subject field(s)
  • Aircraft Propulsion Systems
CONT

Automatically controlled two-bladed propeller.... Designated the Variostat HO-V62A, it is designed for engines up to 100HP... It is automatically protected against overspeed in all flight conditions and maintains constant speed from take-off onwards. All adjustments within the variable-pitch range can be made without the use of a control lever or selector in the cockpit. The pitch change mechanism has its own oil system.... Four adjustments are possible on the ground : fine pitch, coarse pitch, maximum rpm and rpm for reversion to fine pitch.
