Title
(EN) PROPULSIVE ANTI-TORQUE NOZZLE SYSTEM WITH EXTERNAL ROTATING SLEEVE FOR A ROTORCRAFT
(FR) SYSTÈME À TUYÈRE ANTI-COUPLE DE PROPULSION POURVU D'UN MANCHON ROTATIF EXTERNE POUR GIRAVION
Abstract
(EN)
The system of the present application includes a system duct in fluid communication with a tailboom duct, the system duct having a downstream portion with an anti-torque cutout and a pro-torque cutout. The system further includes an anti- torque nozzle exteriorly proximate to the anti-torque cutout and a pro-torque nozzle exteriorly proximate to the pro-torque cutout. A rotating sleeve is configured to selectively allow airflow into at least one of the anti-torque nozzle and the pro-torque nozzle. A thrust nozzle is in fluid communication with the system duct. An upper clamshell and a lower clamshell are each configured to selectively control airflow in the thrust nozzle.
(FR)
Le système de la présente demande comprend un conduit de système en communication fluidique avec un conduit de poutre de queue, le conduit de système comportant une partie aval ayant une découpe anti-couple et une découpe pro-couple. Le système comprend en outre une tuyère anti-couple extérieurement proximale par rapport à la découpe anti-couple et une tuyère pro-couple extérieurement proximale par rapport à la découpe pro-couple. Un manchon rotatif est conçu pour permettre sélectivement un écoulement d'air dans la tuyère anti-couple et/ou dans la tuyère pro-couple. Une tuyère de poussée est communication fluidique avec le conduit de système. Une coquille supérieure et une coquille inférieure sont chacune conçues pour commander sélectivement l'écoulement d'air dans la tuyère de poussée.
