Abstract
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.
Claims8
A method for locking nozzle position in a hydraulic system having a plurality of nozzle actuators connected by a synchronization cable comprises the steps of:
- engaging the synchronization cable with a conical brake locking mechanism;
- preventing rotation of the synchronization cable during a hydraulic failure;
- locking the nozzle in position when a hydraulic failure occurs;
- and
- preventing a significant decrease in usable thrust.
