Abstract

La présente invention se rapporte, selon un aspect donné à titre d'exemple, à un moteur à turbine à gaz qui comprend une nacelle centrale définie autour d'un axe central de moteur, une nacelle de ventilateur montée au moins partiellement autour de la nacelle centrale pour définir un trajet d'écoulement de dérivation de ventilateur pour un flux d'air de dérivation de ventilateur, une buse de ventilateur à zone variable qui est axialement mobile par rapport à la nacelle de ventilateur afin de faire varier une zone de sortie de buse de ventilateur et de régler le rapport de pression du flux d'air de dérivation de ventilateur pendant le fonctionnement du moteur, et un système d'engrenages entraîné par un moteur central agencé dans la nacelle centrale afin d'entraîner un ventilateur agencé dans la nacelle de ventilateur, le système d'engrenages définissant un rapport de démultiplication supérieur ou égal à 2,3.
