LOCK FOR NOZZLE CONTROL IN THE EVENT OF HYDRAULIC FAILURE

摘要

A method is provided for locking jet engine exhaust nozzle position in a hydraulic system having nozzle actuators (102) connected by a synchronization cable (116). The synchronization cable (116) engages with a conical brake locking mechanism (120) to prevent cable rotation in the event of a hydraulic failure. The nozzle (126) is locked in position at the time of the hydraulic failure. This prevents a significant decrease in usable thrust.
