Title
(EN) A GEARED ROTARY POWER DISTRIBUTION UNIT WITH MECHANICAL DIFFERENTIAL GEARING FOR MULTIPLE ACTUATOR SYSTEMS
(FR) UNITÉ ROTATIVE DE DISTRIBUTION D'ÉNERGIE À RÉDUCTEUR, DOTÉE D'UN DIFFÉRENTIEL MÉCANIQUE POUR SYSTÈMES À ACTIONNEURS MULTIPLES
Abstract
(EN)
Methods and systems for nacelle door electromechanical actuation may include a power distribution unit comprising a motor and differential gears; and a plurality of electromechanical actuators, each coupled to an output of a corresponding one of the differential gears. Each of the electromechanical actuators may include a configurable brake and a mechanical output, where the power distribution unit may provide mechanical torque to one of the electromechanical actuators via the motor and the differential gears based on configuration of the configurable brakes in each of the electromechanical actuators. At least one of the configurable brakes may be an electrically configurable brake. At least one of the configurable brakes may be a mechanically configurable brake. The differential gears may include two or more differential gears for receiving an input torque and supplying an output torque to one of a plurality of outputs of the differential gears.

L'invention concerne des procédés et des systèmes permettant l'actionnement électromécanique d'une porte de nacelle et pouvant comprendre une unité de distribution d'énergie comportant un moteur et des différentiels ; et une pluralité d'actionneurs électromécaniques, accouplés chacun à une sortie d'un différentiel correspondant parmi les différentiels. Chaque actionneur électromécanique peut comprendre un frein configurable et une sortie mécanique, l'unité de distribution d'énergie pouvant fournir un couple mécanique à l'un des actionneurs électromécaniques par l'intermédiaire du moteur et des différentiels en fonction de la configuration des freins configurables dans chaque actionneur électromécanique. Au moins un frein configurable peut être un frein configurable électriquement. Au moins un frein configurable peut être un frein configurable mécaniquement. Les différentiels peuvent comprendre deux différentiels ou plus permettant de recevoir un couple d'entrée et de fournir un couple de sortie vers une sortie parmi une pluralité de sorties des différentiels.
