Title
(EN) COMPACT ACTUATION SYSTEM FOR A GAS TURBINE ENGINE EXHAUST NOZZLE
(FR) SYSTÈME D'ACTIONNEMENT COMPACT POUR TUYÈRE D'ÉCHAPPEMENT DE MOTEUR DE TURBINE À GAZ
Abstract
(EN)
Embodiments may include an actuation system for an exhaust nozzle of a gas turbine engine. The actuation system may comprise a plurality of flap assemblies including a plurality of convergent flaps movable between first and second convergent positions and a plurality of divergent flaps movable between first and second divergent positions. Each of the plurality of divergent flaps may extend from a respective one of the plurality of convergent flaps. The system may further include a first sync ring rotatably carried by an engine body and configured to synchronously move the divergent flaps between the first and second divergent positions and a second sync ring rotatably carried by the engine body and configured to synchronously move the convergent flaps between the first and second convergent positions. A method may translate rotation of the sync ring to movement of a vehicle surface between radially outward and inward positions.

Des modes de réalisation peuvent porter sur un système d'actionnement pour une tuyère d'échappement d'un moteur à turbine à gaz. Le système d'actionnement peut comprendre une pluralité d'ensembles volets comprenant une pluralité de volets convergents, mobiles entre des première et seconde positions convergentes, et une pluralité de volets divergents mobiles entre des première et seconde positions divergentes. Chacun de la pluralité de volets divergents peut s'étendre d'un volet respectif de la pluralité de volets convergents. Le système peut comprendre en outre un premier anneau de synchronisation porté de façon rotative par un carter de moteur et conçu pour déplacer de façon synchrone les volets divergents entre les première et seconde positions divergentes, et un second anneau de synchronisation porté de façon rotative par le carter de moteur et conçu pour déplacer de façon synchrone les volets convergents entre les première et seconde positions convergentes. Un procédé peut transformer la rotation de l'anneau de synchronisation en un mouvement d'une surface de véhicule entre des positions radialement extérieure et radialement intérieure.
