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 connected by a synchronization cable. The synchronization cable engages with a conical brake locking mechanism to prevent cable rotation in the event of a hydraulic failure. The nozzle is locked in position at the time of the hydraulic failure. This prevents a significant decrease in usable thrust.
