Abstract
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.
